## Questions & Answers

**Q: How large of a mold will this usually make? One large one? a few small ones? or is there a specified size reccommended?**
A: I molded an object with a volume of 37 ounces but it took a set and 1/4 of another set of these bottles. Safe bet that if you have a model with a displacement greater than the one I did, you need two sets. Some find the simplest way is to pour rice around your model then pour the rice into measuring cups to get a better idea of how much. The hollow mold that I made was about 11.5 inches high and 4 inches in diameter with a width of 1 inch on the sides and bottom of the mold. So.. to encapsulate a volume of 37 ounces with enough material so that the mold was free standing it was a set and 1/4 of silicone at the least. My mold did not have a top though, with a top, it would have been a set and a half, no question about it.

**Q: is this heat resistant?**
A: Not positive but aren't all silicones heat resistant. Great product.

**Q: How many ounces is each bottle?**
A: It is sold and labeled in Lbs.Part A is 1.2lbs and Part B is 1.6lbs and I can't find any label that provides info regarding ounces.  The dimensions are almost the same size as a 16 oz bottle so it's close to 16oz per bottle but that it an estimate.  Sorry I can't provide more info.

**Q: Is it enough liquid to make a 12" vinyl record mold?**
A: One would probably be enough, but it would be a thin coat. If you want the mold to be more durable, might go for a second just to hold the shape better.
