Mandala #20 — Ca: Calcio (Calcium)
Element 20 · Ca · Calcio
Bone white, terracotta flame
The element of bones and shells — forming limestone, marble, concrete, and the skeleton of every vertebrate.
Calcium carbonate forms limestone, marble, chalk, and seashells. As hydroxyapatite, it makes bones and teeth rigid. Its brick-red flame test (622nm) identifies it in fireworks. Calcium ions trigger muscle contraction and release neurotransmitters.
