All,

I've been hearing how winding coils on discarded plastic pill bottles
is not suitable for RF tank circuits due to low Q, and that these would
not be safe for tube circuits anyway due to melting point.

I have access to kaolinite clay (white porcelain) and a kiln, and I was
wondering if I molded and fired this type of clay for coil forms, what
effect on a tank circuit Q this form would have.

Thanks in advance,
