Viva La Cake Uses ComposiMold for a Very Important Part of Her Carousel Cake

Our friend Joly Diaz of Viva La Cake ( had a problem! The pre-made mold she bought for her carousel cake was not going to work! 

"I got a mold specifically for this cake, but the horses faced the opposite direction to the turn table movement. I had to use a toy horse and use your product to get it done right. It was awesome and sooo helpful."

We were so happy to hear that having ComposiMold in her cake decorating tool box, empowered her to make her cake as she envisioned it...horses galloping forward, not backwards.

Then she did a little experimenting with making her own master object to mold:

"Then I made a horse in fondant, let it dry, poured your product over it and it also worked!"

With this technique, you can truly make one-of-a-kind cakes!

Thank you Viva La Cake for sharing your awesome project. We were very impressed with this work of art.

How to Make A Resin Bracelet

How to Duplicate a Resin Bracelet Using ComposiMold Reusable Mold Making Materials

I chose a bangle bracelet that was pretty complicated with holes throughout to demonstrate how you can make complex objects with a simple mold.

To start making your resin bracelet:

Hot glue the original bracelet, or master, to the bottom of the container. Melt the ComposiMold in your microwave or use a double boiler to heat. Pour the ComposiMold over and around the bracelet. Use a paperclip, piece of wire, or toothpick to pull away any bubbles from the crevices in the bracelet. We also recommend spraying the part with Bubble Buster to reduce bubbles from sticking to the part.
And let the mold cool to solidify. In the freezer, this mold would take a couple of hours to solidify into a nice rubber.

Now, cut out the original master object from the mold box. We do that by cutting away the plastic container as that’s typically easiest.

Cut along the bottom of the mold and cut the holes within the bracelet to pull out the original.
This hole between the mold makes this a pretty complicated shape, but still doable just by cutting.

Pouring the Resin into the Bracelet Mold

We’re using ComposiCast White resin with a little black colorant to make a gray bracelet. Mix in a few drops of colorant into the ComposiCast.Mix the two parts of resin together 50% of each. It’s extremely flexible so if you accidently use too much or too little of one, you should be fine. Try to err on the side of more resin and less hardener. More Part A and less Part B. Pour the resin into the mold cavity and let it cure overnight. 10 hours later, you are ready to pull out the duplicated casting.

Cleaning up the Casting 

Clean up the casting by cutting off any extra resin, sanding away any blemishes, and you are ready to go.
This is a challenging mold, probably about a level 4 out of 5, 5 being the hardest, so start simple and work to more complex molds. And you can do that all with the same ComposiMold, since it is re-usable. With ComposiMold, you can make dozens of great unique molds with the same molding material.

Thanks for watching, and let us know what questions you have.

Making Unique Molds for Polymer Clay with ImPRESSive Putty

Polymer Clay Molds That are Awesome

Polymer Clay Push molds are very easy using FIMO or Sculpey, Polymer Metal Clay (PMC), Plasticine clays, and other clays. You can even use the Formable Plastics.The ComposiMold and ImPRESSive Putty give you the ability to make, and re-make the clay molds using an original shape that you then re-cast in molds by taking the original to be molded and also to make the  castings. 

We recommend the ImPRESSive Putty or the ComposiMold-Firm for firm clays To use, just press the polymer clay into your molds and pull the clay out.  Do not bake the polymer clay in the molds. 

Using ImPRESSive Putty for Clay Molds

Clay Push molds are a simple and effective way of making 3-D objects super fast and easy. For example, buttons can be pushed into a mold in seconds flat using most types of polymer clays or doughy casting materials. It's a great way to make polymer clay charms for jewelry.
ImPRESSive Putty is a great way of using natural objects or making a large number of castings quickly. Soften the ImPRESSive Putty in the microwave. A 6 oz. size of ImPRESSive Putty softens in about 40 seconds in most microwaves.
The video below shows the re-melting of the ImPRESSive Putty from the leaf to make a candle and candle holder. This is a two part mold for polymer clay.

To Mold Clay in a ComposiMold Mold: 

Mold clay and polymer clay by using ComposiMold. Air dry clay and other modeling clays make excellent and simple casting materials to mold clay into the shapes you want. You can learn how to make clay molds with ComposiMold quickly and easily. Use an existing found object to create a clay mold or even sculpt your own master object and then make a mold out of it. You'll be creating duplicates of your sculpture in no time!
Follow the basic instructions on our How To Use ComposiMold Page to make a mold with ComposiMold. The tips below will set you up for success when creating a great push mold for polymer clay, FIMO, Sculpey, play dough, PaperClay, and even fondant or gum paste for edible shapes. 

The Keys to Making Clay Push Molds in a ComposiMold Mold: 

Think of a push mold as a negative space for you to press your casting material into to pick up the details of the original shape.

1. Soften your modeling clay or air dry clay per product instructions. Often this means working it in your hands until it has warmed slightly and becomes doughy in texture.
2. Apply Mold Release if you find that it helped your modeling clay release from the mold. 
3. Press your clay casting material into your mold. Be sure to press the clay into the lowest points of the negative space first. This will ensure that the clay casting material picks up all the details of the mold. 
4. Carefully remove your clay casting from the mold. This can be done by turning your mold upside down and letting it fall out. (You may have to slightly bend your mold away from the clay to release it.) 
5. If your modeling clay distorts when you pull it out of the mold, refrigerate the mold and clay. This will make the clay harder and firmer allowing you to pull it out of the mold more effectively with less distortion.

The 5 Levels of Mold Making Expertise

Mold making and casting is a craft and skill that requires practice to become better. Like learning to play music or sewing, there are certain skills that are easier than others. Here we look at the different skills and try to separate them into levels of proficiency.

Level 1: Simple Relief Sculpture Mold Making

A basic shape with no undercuts. Short sides so you can push in a casting material or it’s a simple pour.
Examples: one side of a button, a cookie shape, a pendant, or a stamp. This also includes large molds like concrete stamp pads or stepping stones.

Skills : Melting/using Reusable Molding Materials. Creating mold box (if used, ImPRESSive Putty doesn’t need a mold box). Understanding molding process. Creative design and use of casting materials. Almost anyone can do these types of molds and it’s a great way to explore mold making in classrooms.
Lots of our fast video examples are level 1 molds:

Examples include:
Custom soap molds:
Polymer Clay push mold decals:
Polymer clay leaf:
Lace in fondant:
Button molds with ImPRESSive Putty:
Soft bait fishing lures:
Restoring frames:

Level 2: Basic Undercuts with a flat bottom Mold making

Relief sculptures with undercuts that can still be removed by pushing out the shapes. Examples include
Chess piece, some figurines, many sculpture pieces.
Skills: Level 1 skills and a little more confidence to push and pull on the molds to get the castings out.
Big chocolate gnome:
ImPRESSive Putty Building Renovation project:
Resin Casting of Toy Stone Wall:

Level 3: Intermediate mold maker

Cut Block Molds and brush on molds would fit in with the intermediate mold maker.
Skills include: figuring out where to cut the mold to create a parting line, planning how you will get your part out of the mold. Here’s some video examples:
Big Plaster Duck is Level 3 because of the duck bill and head, but it’s still pretty simple with the a single pour mold:
Cut blog chocolate figurine:
Resin Casting Action Hero:
Chocolate high heel shoe:
This is a big concrete dog, but the basics are the same:

Here’s a brush on mold (now I’d just press on ImPRESSive Putty to do this)

Level 4: Advanced mold maker

Two Part Molds, deep undercuts, multiple parts, thin walls. The skills needed include creating parting lines, and designing sprues.

Combining ImPRESSive Putty and ComposiMold for a Thin Walled boat hull plug:

Two part mold action figure:

Just the size of the chocolate horse’s head makes it a challenge:

Level 5: Master Molder

Some things, no matter how simple the mold making material is to use is complex. It will take thinking, expertise, and experimenting to make the complex molds. We endlessly are asked how to make a 3 part casting of a giant (or microscopic) dragon with wings and horns with movable arms, head, and legs, plus the rider carrying swords, a backpack, and hallo. Our response typically is to start simple and expand your skills by moving to more complex. Because ComposiMold is re-usable, start with the dragon’s head or the sword and work up to the more complicated. You will make mistakes, and you will need to experiment. And that’s why ComposiMold exists. So you can learn, experiment, and create as you like.

Here’s some examples of some pretty complex parts. Each individual piece of a Lego person that can be used to make an entirely new usable Lego person. Full moving Lego person: (3 full length parts going through the entire process)
Making a hollow/movable parts Shopkin’s Toy:

The casting materials you use are somewhat immaterial of your molding level. You can use epoxy resin or plaster or chocolate for simple molds or complex mold making. Exceptions for ComposiMold include using ComposiMold for the lost wax process or high temperature sugars in ImPRESSive Putty.

While in many cases the casting material doesn’t matter, some molds ARE more complex because of the materials being molded or cast. For example, isomalt is challenging to work without practice. See it being used with the Food Safe ImPRESSive Putty here:
And higher temperature waxes can be a challenge with ComposiMold (but not an issue with ImPRESSive Putty)

And Bath Bombs are challenging, not because of the mold making but because the bath bomb mixture cannot have a lot of water in it, but it does need some:
Jell-O or Gummies can be a challenge initially typically when the gelatin mixture is poured too hot. So by letting it cool, the process becomes very simple. Here’s a gummy Lego example:

When making the mold, you can sometimes run into challenges that are more complex includimg the molding of low melt polymer clays like Plasticine or molding frozen object. This requires the ComposiMold to be poured after it has cooled a bit and keeping the objects cold.

Which level are you?

So what molds have you made? Are you an intermediate mold maker? Advanced?

We’d like to add on these descriptions, so any thoughts and suggestions from you would be helpful. We’ll be updating the information in our blog ( as well as our Learn to Mold section of our website.

Thank you and keep making awesome!

Chocolate Peas and Corn. For the next time someone asks you to eat your vegetables.

Fred asked about molding frozen peas to make Chocolate Peas and Chocolate Corn. He wanted to "mold pureed peas (and other foods) so that they look something like a "pile" (portion) of peas (or other). There are molds out there, but they look like a couple half rounded & melted peas when they are done (frozen food put in place)." You can see some great pro cooking tips on Fred's blog: . 

What a cool project! I have seen corn on the cob molded, broccoli, sliced tomatoes, and carrots, but I love the idea of a bowl of vegetables that's actually chocolate. It makes such a dichotomy to my senses between tasty chocolate and healthy vegetables :)
Chocolate Corn made with ComposiMold Mold

So it started when Fred asked us what he was doing wrong after his first attempt didn't work so well. The peas had melted and the ComposiMold was a bit guey and it wasn't a fun mold. I believe the reason for the not-so-healthy looking mold was there was too much ice with the peas so that when the water melted it damaged the ComposiMold. This was a great example of using ComposiMold for experimenting, making something very unique, and creating a challenging and fun chocolate mold.

My turn to see. I reached into the freezer and the first vegetable I pulled out was corn, so I used corn for my chocolate vegetable. I poured some frozen corn into a small bowl about a 1/4 to 1/2 inch thick. Enough to cover the bottom but not so much that the ComposiMold will run in and around all the corn pieces.

We debated whether the vegetables should be glued together or placed in jello or fondant so it would stay in place, but it was decided that we'd lose details that way. And since it's ComposiMold, I figured we could experiment. If just pouring it into a cup didn't work, we could try it again. So the frozen vegetables are in the cup, and they are not glued in position.  I could have also coated the corn with vegetable oil as a release agent, but it wasn't necessary.
Vegetable Mold with ComposiMold poured over the Corn

We melted the ComposiMold, but after it was melted we didn't pour right away. We let it cool so it was thicker before pouring. This way the vegetables wouldn't float, and the ComposiMold would cool faster before any water reacted with it. After we poured the ComposiMold over the corn, we placed it back in the freezer to finish cooling and to keep the corn and ice from melting.

Then I forgot about the mold. Whoops. Several days later Fred asks me..."so? What do you think?" Sorry! I hurried down to see. 

The mold was great. I pulled out the corn. The mold was ready.

I took a piece of tape and wrapped it around the mold to make a little mold box.

I melted chocolate...first  green chocolate to make it look like Peas. And then yellow chocolate for corn.

Cooled it in the freezer.
Chocolate Poured into ComposiMold Mold.

Pulled out the mold, carefully pulled the mold away from the chocolate. And voila, a chocolate vegetable.

Go eat your vegetables.

6 Alternatives to Fondant for Cool Cake Decorations

The joke about using fondant for cakes is you should Fon "don't". Ask 10 people if they like the taste of fondant, 6 will say the dislike the taste, 2 will like it, and 2 will not know what fondant is.

So what is Fondant?

Ingredients-wise fondant is a sugar and water paste that is used for making cake, cupcake and cookie decorations. It can sometimes have a little glycerin, corn syrup, and flavorings in it to make different flavors and colors and textures. 

Why do we use fondant for cake decorations?

So you can make beautiful and amazing cakes. The advantage of fondant is that it allows you to make unique decorations by shaping the paste either with molds, like we do with ComposiMold molds, or by hand. It looks beautiful and allows the cake decorator to make amazing creations. AND, you CAN have fondant look and taste amazing. Stay tuned, we'll talk about that below.

Why do so many people dislike the taste of Fondant?

My opinion on why people dislike the taste of fondant is that they have only tried the lousy brands. The typical fondant that people first try is the junk bought at the box store or chain art stores. The comparison would be to say you hate hamburgers because the only hamburger you've tasted came from McDonald's. There are so many incredible options out there or you can make it yourself to make extremely tasty fondant for your cakes. 

But sometimes you want other options.

Alternative to Fondant for Cake Decorating

1. Use better fondant. There's two options for using better fondant, either make it yourself or buy better brands. Making fondant is relatively easy. Many like the marshmallow flavored fondant, but other versions taste great too, if made well and with quality ingredients. The disadvantage to making your own is that it doesn't last a long time. So if you're making a cake, not only do you have to deal with the cake making, now you have the fondant making, before you even get to the cake decorating part. So it can be a huge time-saver to just use pre-made fondant, just don't use the junky fondant.
  • 1 (.25 ounce, 2 full teaspoons) package unflavored gelatin
  • ¼ cup cold water
  • ½ cup glucose syrup or corn syrup
  • 1 tablespoon glycerin
  • 2 tablespoons (1oz/30g) shortening or butter
  • 1 teaspoon vanilla extract
  • 8 cups sifted confectioners' sugar

Mix together. There's also tons of recipes out there for the marshmallow recipe. 

Alternatives to making your own fondant, there are many very good tasting brands out there. Of the large brands, Satin Ice  is probably on the better side. Choco-pan is nice. And Pettinance is a great taste. And they are great for mold making.

2. Use gum paste. It's very similar in texture to fondant, but is closer to the typical buttercream frosting. It's made with egg, shortening, and confectioner sugar. For the longest time, this was my go-to frosting recipe for sugar cookies and gingerbread cookies.

3. For decorations, use isomalt.  I couldn't imagine covering a cake with this, but it's great for decorations and is very popular in many cake decorating competitions. It's basically a hard candy that you can form by melting. The isomalt is not sugar based. You can find lots of isomalt options at simi-cakes

4. Use sugar candy. You know the candy apple material? It can be almost any flavor and like isomalt, you can make some amazing designs. The recipe is super easy. Check out the previous blog posting on how to make the sugar candy for mold making.

5. Chocolate! My favorite. I love chocolate. And you can make it act almost exactly like fondant by adding corn syrup. The chocolate comes in many variations. For molding decorations, you can use the chocolate as is. If you want to make it moldable, you can use modeling chocolate, or candy clay, or chocolate modeling clay as it's sometimes called. I've seen it also called chocolate plastic, which I think is a great description. Chocolate plastic is just chocolate melted and then corn syrup is added to it to give it some flexibility.

6. And if all those alternatives to fondant don't get you excited, you can use frosting. You know that's tasty, and works. 

Well, there are 6 alternatives to fondant for cake decorations. What did we forget? What alternatives do you use?

How to Make Your Own Isomalt and Hot Sugar Molds with a Food Safe Reusable Molding Putty

Isomalt is a nice sugar substitute that can be melted at relatively low temperatures.You can make some amazing shapes and designs using Isomalt for cake decorations, no-sugar candies, and cupcake toppers. You can also use pulled sugar. I'll give you the recipe we used for pouring or pressing sugar into the molds below. 

Start with the shapes that you want to make into sugar or isomalt candies. Clean these shapes well. Now prepare your molding material by softening the ImPRESSive Putty in the microwave for about 45 seconds for this 6 oz size. We also have 1.5 oz, 1 pound, and 5 pound sizes available.
Let the putty cool so it’s easy to handle without being too hot, but still moldable. You can actually let it cool to below 100 F and still form it as we do here.
And press, thus the name, the putty over your shapes. Here were using some tool shapes to emphasize that this is your tool for creative mold making.
After you have pressed it over your shapes, let the mold cool. In the freezer this takes about 20 minutes to solidify to a rubber. You know it’s ready when you press on the mold and it doesn’t leave an indentation.
Pull out your original shapes. First the adjustable wrench, and then the pliers. You will notice that the Putty is still flexible enough to bend around the shape, but firm enough for press molding.
Oh no, there’s a small hole in one of the molds.Luckily, you don’t have to worry.
Good thing this is a reusable molding material. With just a little heat, you can fix the mold or reshape it. Just take a piece of the Putty from somewhere else and reheat it. We do this with a hot air gun, but you can also use a hair dryer or other heating source. This is one of the big benefits of ImPRESSive Putty. You can re-melt and re-use any time you want. We place the pliers back into the mold to keep the shape while we reform the putty to fill the small void. Heat both parts of the mold so the parts will stick together. And just like that. In about 30 seconds we fixed this mold and we are ready to pour in the isomalt.
We melted the isomalt in the microwave.
When you pour the Isomalt into your mold, be sure it has cooled to around 200 F. For larger isomalt candies you may need to chill your mold a bit. However, you want to try not to chill it if you can so that the isomalt will flow into the crevices of your mold better, so experiment with your shape. At any time you can re-make or fix your mold, so don’t worry about breaking anything.
Now just pull out your casting and admire.
To keep a nice shiny finish, you should spray the candies with an edible glaze. 
And because this is reusable, you can re-melt or re-soften the putty Any Time You Want to make a new mold. In the video, we used a key chain of a volkswagon beetle car. Now it’s going to be a lollipop.
We used 1.5 ounces of putty for this small lollipop mold. This is the same size as our small trial size Molding Putty. Heat in the microwave for about 14 seconds, let cool so you can handle it easily, press over your shape, let cool. Cut a little slot for the lollipop stick.
Pour in your isomalt, add your lollipop stick, let cool, tada…admire.
You Can Use Sugar Candy Molds Also
Now we show this same mold with pulled sugar. Pulled sugar castings are more advanced. Let the Pulled sugar cool to about 200 F or below before pouring into your mold. Here we basically pressing the pulled sugar into the molds and use the mold as a press mold. Be careful both hot sugar and isomalt can burn. Gloves are recommended. Add in the lollipop stick and you have yourself a creative and unique lollipop and candy treat. So these are just a few things that you can make, let your creativity go wild. The ImPRESSive Putty is very easy to use, so experiment and let’s see what you make.   
The pulled sugar recipe included:
2 cups sugar
3/4 cup light corn syrup
We also added some red food colors. We could have also added some flavorings. We cooked this on the stove to above 310 F and held it there for 7 minutes.
We then let the sugar candy cool.  When the sugar candy cools to  below 200 F, you can pour or press the sugar into the sugar molds made with the Food Safe ImPRESSive Putty. You do have to be careful that you don't pour the sugar candy into the molds while it is too hot or you will melt the molds. 
This is a great way of making very cool looking lollipops.

Casting with Plaster of Paris and ComposiMold or ImPRESSive Putty

Casting with Plaster of Paris

ComposiMold Plaster of Paris Casting from a real seashell
Seashell in Plaster of Paris
Plaster of Paris is low cost, easy to use, and makes good castings. Plaster of Paris comes as an easy-to-mix formula that mixes with water and dries to a dense, durable, and smooth and bubble free finish. Plaster of Paris is a great material to use for basic castings and molds and art projects because it is simple to mix and use. The Plaster of Paris sets in a few minutes, although it takes an hour before it is ready to be removed from the mold. It takes 24-48 hours to fully cure. Using Plaster of Paris is easy, but there are procedures to follow that will make you successful in your plaster castings.

ComposiMold Plaster of Paris Casting of frogs for a garden
Plaster Casting of Frogs
Plaster of Paris is not a plastic. It is a hard white substance made by the addition of water to powdered and partly dehydrated gypsum. It is hard like a cement or concrete but white and not as strong. So don’t use plaster for very thin castings. Basic shapes or designs that have a solid backing to them will be more successful. If you need some flexibility or stiffness in the final castings, then move to a plastic.

Materials you will need:
·         Plaster of Paris powder. For ComposiMold or ImPRESSive Putty Molds, please use our ComposiMold plaster that has been formulated to cure to a strong solid casting in these molds. By creating cure more quickly, the water in the plaster does not react with the ComposiMold or ImPRESSive Putty to give strong, hard plaster castings. You can also purchase a powder additive to add into any plaster of paris to obtain a similar affect.
ComposiMold Plaster of Paris Casting
·         Water: Use cold water to cure slower and give you more control over the reaction and give more time to fill the molds.
·         Mixing container that is large enough to hold to water and plaster. Plastic containers are nice because you can deform them afterwards to break away the hard plaster and re-use the container.
·         Measuring cup or any cup that can be used to measure out 3 parts of plaster powder to 1 part water.

Make your Plaster Castings

The ideal ratio for a Plaster of Paris mixture is 3 parts Plaster of Paris powder to 1 part water. Measure out the water and pour it into your mixing container. Some recipes suggest 2 parts plaster to water, but this will create a much weaker plaster casting. The thicker you can be while still being able to pour the better. Start with a 3 to 1 ratio and if necessary add small amounts of water to make it easier to pour.

Break any clumps of plaster up with a spoon. If you use your hands to mix, be sure to wear gloves.

When mixing the water and plaster, you should mix the powder into the water.  Pour the plaster powder into the water spreading it out over the surface of the water. After it is poured all poured in, tap the sides of the mixing container and let the plaster powder fill with water to reduce bubble formation. The plaster powder will sink into the water. When you are finished adding the plaster, it will be slightly above the surface of the water and not easily absorbed by the water.

Gently stir the plaster and water to form a nice slurry similar to a thick pancake mix.  Gentle stirring of the plaster will reduce the chance of bubbles being mixed into the mixture.
Pour the plaster into your molds. If you want to learn how to make your own molds, check out our mold making videos and get your free mold making e-book.

A couple other tips for plaster casting:
Do not pour any extra plaster down your drain. It can harden and destroy your plumbing. You can dilute the plaster so it does not create a hard plaster or let it harden and throw it away.

To make colored plaster, you can add colorants to the plaster mix while it is still in liquid/paste form. Remember that you will be adding color to white, so you will need more colorant to make darker colors. Any types of paint will work.

To paint the plaster casting after it has cured, use a layer of gesso or primer first to seal the plaster, and then you can paint the plaster any way you want.
