BIO-CERAMICS (Calcium Carbonates)

• "Calcium in Pottery: The Good, the Bad, the Ugly" — Ceramic Technology Lab, Florida Museum of Natural History (2020) Explains how calcium carbonate from shells and limestone shaped pottery traditions across Native American and Caribbean cultures — including why it's chemically tricky and how ancient potters worked around it.  https://www.floridamuseum.ufl.edu/ceramiclab/blog/calcium-in-pottery/

• "Calcite (Chalk) — Types, History and Use in Oil Painting" — Natural Pigments A deep-dive into calcium carbonate as an art material: from prehistoric cave painters grinding chalk into pigment to Renaissance gesso grounds to modern paint making. https://www.naturalpigments.com/artist-materials/calcite-oil-painting-history-types

• "Conveying the Fragility of Coral Reefs: An Interview with Courtney Mattison" — Arts Help Mattison is a ceramic sculptor who hand-builds massive coral reef wall installations for NOAA, the U.S. Embassy in Jakarta, and museums worldwide.

• "Cracking the Case: The Art of Eggshells" — Yale Engineering A New Haven ceramist named Kiara Matos partnered with a Yale materials scientist to replace mined calcium carbonate in ceramic glaze with discarded eggshells.
