Hi /diy/,
I'm thinking of making an electric incense heater/burner for resins (like pine, myrrh, frankincense) by embedding a length of kanthal wire in some kind of thermally conductive, but electrically insulating material. I expect the max temp of the heater will be less than 500F. Would plaster of paris be a good material for this? Or should I use some kind of castable refractory? Thanks.

put some rock wool in it and it should be fine

A relatively cheap way is a 50/50 mix (by volume not weight) of perlite and plaster of paris.
