Best clay for candle holders

Best clay for candle holders?

I want to make some candle holders,but I don't know what clay to use. I can get either white polymer clay or white air-dry clay.

Will the heat of the candle destroy the clay?
If I cover it with acrylic topping, will it catch on fire?

Thanks!

If you want to make votive candleholders I suggest you go to your local thrift store and buy small, clear glass votive holders, and cover them with polymer clay for a nice glowing effect. The glass protects the clay from getting burned, and nothing will catch on fire!
