COMMON QUESTIONS
HOW TO AVOID BUBBLES? WHY THERE ARE BUBBLES SOMETIMES?
SILICONE RUBBER IS A TEMPERATURE SENSITIVE MATERIAL! It is recommended to operate in an environment of 70°F-80°F.
• When it's too warm, it's thinner and sets faster. Silicone molds may set too quickly and become too hot, The self-defoaming ability becomes weak, causing bubble problems.
✔ It is recommended to put the MIXED liquid silicone rubber in the refrigerator for 1-2 hours and then take it out to cure at room temperature, which can effectively solve the bubble problem. (ESPECIALLY FOR SUMMER)
• When it’s too cold, it's thicker and sets slower. Silicone molds may become too viscous to properly release air and self defoam. Therefore there will be some bubbles.
✔ It is recommended to soak parts A and B into warm water SEPARATELY and use them when the low viscosity is restored. (ESPECIALLY FOR WINTER)

There was a problem filtering reviews right now. Please try again later.
There are a LOT of reviews in the 1 and 2-star range that say this stuff never cures. Lately, I discovered the same thing. My molds were less and less set and more and more sticky. This bothered me deeply because the first mold I ever made with MiracleKoo set perfectly and serves me well!
I read online that certain chemicals can inhibit the curing process, and sulphur is one of them. *ding* I was like, "Oh my Dog!" So, I got some non-sulphur plasticine clay, made a tiny little test piece with plenty of detail, and cast it. Perfection!
I am serious! The last mold I tried to make failed miserably! The product never cured completely and left a layer of sticky, sloppy silicone on the original (which was made with sulphured plasticine!) The outer surface of the mold was also tacky and sticky to the touch. This next test was made the exact same way, only with non-sulphur plasticine.
I want to write the manufacturer and tell them this so they can tell everyone! I want to go through every 1-star review and contact the customers to let them know what I learned!

Make sure to read the entire thing TWICE to make sure you fully understand each process.
Good price point for a small project , if you need more i would probably look for a more budget friendly option .
I would recommend to people trying to learn or dip into the art of silicone mold making.

On the great side, this liquid silicone makes beautiful molds. Very detailed and bubble free. I've made more than just the two I pictured, and have used them quite a few times before writing this review.
A lesson I have learned.
As much as you think it's better and less expensive, don't use cardboard. I did on my first few molds, and it leaked if I didn't seal it enough. I lost product that way. Use foam core board. It may not be free like cardboard, but it's worth it. One sheet makes a lot of mold holders.
A glue gun is a must. It seals all those crevices. I use 2 different types, depending on the mold I'm making.
Don't waste space. If you can get more than one piece in a single mold, do it. I should have added more to the one I had multiple pieces in. I had too much wasted space and product.
Because this is clear, it will be harder to judge where the material is on top of the piece you are molding. I use a pin to judge where it is, so I know if I need to add more product or not. If it has too thin and area in any spit, the mold will rip.
All in all, I really like the product. I've had so much fun with it, and it has given me many more ideas for my resin creations.
