Notes
(Richard Willis)
The gaseous oxide of carbon, of the ideal form CO2, making up and, with heat, releasable from the solid carbonate form, CO3: one of the causes of blistering and resultant cratering/pinholing of glazes, thus making it advisable to calcinate carbonates before use in recipes; or to fire slowly through the calcinating temperature range (usually 500-1000ºC) to allow gas to escape before the melt seals it in. It is present and potentially releasab
le in both inorganic carbonates — sodium carbonate, calcium carbonate, etc., and in organic materials such as flora and fauna “ash” or “oil”.
