Calcium carbonate is a central substance to the chemistry of Novogenesis. It is available from a large number of sources, relatively safe chemically and biologically, and provides routes to and from a large variety of other salts via metathesis and thermal decomposition. Its insolubility and nontoxic nature make it an ideal metathesis product.
- Pharmacopia: Antacid
- Source of carbon dioxide by thermal decomposition
- It occurrs naturally as the minerals calcite, limestone, and chalk, among others.
- Sea shells and egg shells are primarily calcium carbonate
- Some white sand is primarily calcium carbonate
- Chambliss Rock Collecting Area
- Marble Mountain Rock Collecting Area
Calcium carbonate exposure and ingestion are relatively safe. Its unreactive nature makes it fairly bio-inert. Inhalation of fine powder is safER than the inhalation of almost anything else.
- Gathering any of the naturally occurring versions
- from any soluble calcium salt (-hydroxide, -chloride, -acetate, etc)
- via bubbling carbon dioxide through the solution, causing the carbonate to precipitate.
- via metathesis with another carbonate compound
- from -oxide via exposure to air
