I have been processing limestone for my upcoming class on Natural Glaze Materials . I found some limestone and put it in this bowl/saggar/container and bisque fired it. When it came out, it looked about the same so I added some water and it proceeded to decompose into this powder.
The bisque is driving off the carbon dioxide and so you have CaO. When you add water it is an exothermic reaction which turns the CaO back into cacium carbonate.
Clay Club meets at artist studios and other locations throughout Western North Carolina, usually on the second Wednesday of the month. All potters and ceramic artists are welcome! Look for details about the meetings here on the blog or contact Amy Waller at email@example.com for more info.
