What is Salt Firing?

Soda Firing

Soda Firing
The soda or vapor firing is similar to the salt firing, except that the salt is substituted with sodium carbonate (soda ash) or sodium bicarbonate (baking soda). The sodium (bi)carbonate delivers the necessary sodium for glazing, but the effect is much weaker. Often the interiors of pots do not glaze well, so extra glaze may need to be applied. But as carbon is additionally generated, instead of hydrochloric acid, this is an evironmentally friendly alternative.
