## Questions & Answers

**Q: Can this be used to mold body parts? Hands, face, feet, etc?**
A: I do not believe this is the intended use.  It gets pretty warm.   There are other products for molding body parts available.

by Smooth-On

**Q: can this be used for casting tin, which melts at 450 degrees?**
A: NO! You need to use Mold Max 60

**Q: Can I use this to make a mold from a clay ?**
A: Yes, works great.
However, use a clay that does not have sulphur. There are many clays available for this use. Sulphur can inhibit the curing of the silicone.
This silicone is really great; easy to use but be careful to follow directions and use the appropriate ratio.

**Q: Which smooth-ons do you recommend for making bracelet beads that are not so shiny, like glass or pearls, but rather look like neoprene or rubber?**
A: For this, I would only recommend an FDA resin. If one person has a reaction, it could be bad and you could get sued
