KILN - Fumes

ca: FORN - Fums

es: HORNO - Humos

Kiln fumes appear during the early stages of firing while the kiln is heating up. The evolution of the clays and glaze forms vapors which can be inhaled and some are toxic. Make sure you know what you are playing with, that your ventilating systems are good and if necessary wear a mask. When firing transfers, the smell is awful. The first time I fired them I did not warn my neighbors and they all came down to tell me that the sewage pipe that went under my patio must be obstructed or blocked. In large kilns, ventilators or chimneys are usually installed but not in small ones.
