Review: Easy to mix and pour, makes great molds. - Mixed well, degased ok, had to vacuum it twice but made a really nice strong cast for my candle mold. It could be cheaper for the amount you get, but depending on your budget if it's worth it or not. The whole container made one 3" x 8inch candle mold, I use round shipping tubes to make my molds in.
Review: So easy to use - I can not be happier with this product. It worked like a dream. We didn't de-gas it, as is recommended, but after filling the mold, we did bang it on the counter like crazy. Seems to have worked well enough because there wasn't a bubble or imperfection to be found in the silicone mold. I sprayed the 3-D printed mold with non stick spray and that also worked just fine. It was a bit tough to remove the silicone from the 3-D mold, but only because, the way we designed the 3-D mold, there was no good place to grip and pull out the silicone. We were able to pry it out without any real trouble though. We used ours to make a Giant Sour Patch kid, and the gelatin mixer came right out of the silicone mold. It looks absolutely perfect! I can't wait to make up a whole army of Sour Patch kids for our daughter's birthday.

## Questions & Answers

**Q: does this need to be de-gassed?**
A: A good trick when not degassing your 2 part silicone is to pour very slowly, from a greater than normal height, and let the stream become extremely thin and stretched as it is poured.  Always pour at the lowest part of your mold to avoid unnecessarily trapping air bubbles.  Let the liquid "wash over" your model.

**Q: Can you make a dildo with it?**
A: Lol yes you could produce such a thing with the right mold.

**Q: Is this product microwave safe?**
A: Yes as long as temp does not go above 450f

**Q: how much product does this kit make? Like if you were to use it all up and make one big cube of silicone, how many square inches would it be?**
A: I filled up 3 6oz. yogurt containers and had enough for at least one more if not two.

### ⭐⭐⭐⭐⭐ Lego gummies
*by K***E on September 28, 2022*

Me and my siblings used this to make lego molds to use for making gummies. Watch the "The King of Random" video about this, and this amazing guy walks you step by step how to make it. The instructions on this too are clear and easy to follow. Just remember it is very sticky when making it so use something that's not precious to you. But it did it's job and can make perfect gummies!
