## Questions & Answers

**Q: How long does it take to be hard enough for taking the mold off?**
A: In general, you should be able to remove the mold from the plaster in 20-30 minutes.  My experiences is with small, shallow casting between 1/2 to 1 inch thick. 
 The casting will remain wet for up to 24 hours, depending on room temperature, so be gentle in removing the mold.

**Q: Anyone know the difference between this and the high strength 20 plaster made by the same company?**
A: No

**Q: Can low temperature metals (pewter) be cast in this plaster?**
A: Probably not....

**Q: Can this be used for making molds for pouring porcelain? The molds would be placed in a kiln and fired at a high temperature for the porcelain to cure**
A: I don't see why not?  I made bats to dry out my recycled clay, so I haven't put them in the kiln, but it's just regular plaster used in ceramics as far as I can tell.  You might want to test one before you commit to putting your work at risk.  You could also buy plaster from a clay vendor whom you can ask to make sure it is kiln-worthy.
