I am looking into a kiln for heat hardening silver. I have looked through the archives and have some tips. My needs are strictly for hardening at this time but I can foresee enameling as a possibility. My wonder is the economics of buying or building. What I see in the kilns at the sires I have visited is pretty basic technology. My biggest concern is temperature control. (Ventilation is handled already in the shop.)
Is there a minimum practical size for the chamber? Is there a limitation to efficiency based on cubic capacityof the chamber and the amount of pieces being treated?
Is there a best brand? The Durston of KIlns so to speak.
