Q:Question about micaceous clay

 I have been asked if items made from micaceous clay can be used in the 

microwave and haven't been able to find an answer.

Can you tell me?

A: The problem is that the microwaves heat up water, micaceous clay will have a lot of water in it as it is soft fired and not waterproof. This water will get very hot, making the pot very hot, as hot as the food. If the water turns to steam and can't get out the pot may explode.

 

I put a very dry, fired, test tile in the microwave for 30 seconds and it was unaffected.

A: We recommend a maximum temp of cone 08, higher than that and the shine fades.
