## 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.
