Cochineal Extract
A mobile-first interactive natural-dye chemistry toy. Drag pH and swipe through six mordants to shift a live cochineal (carminic acid) dye bath's colour, computed from real anthraquinone chemistry, and match twelve target swatches. Dye-bath exhaustion makes successive baths paler. Share the finished dyed plate to the Eazo community.
