Did you mention, Russ, if the crazing on these beads is a surface treatment or if it appears inside the bead, too? I was browsing through an older polymer clay techniques book, and found a recipe for faux turquoise I hadn't seen before. After conditioning the clay, it's broken down into smaller chunks and "crumbles". Each of these small pieces are coated in acrylic paint, THEN pressed gently back into a bead or slab. The excess paint on the outside is wiped off, leaving residue in the cracks and crannies. With this method, the "matrix" shows all the way through the bead (if you were to slice it open) rather than just on the outside of the "turquoise" bead (when the paint is applied after baking.) I'm wondering if the crazing on these magnesite beads might be produced in a similar matter? (The ones that show irregular matrix, as opposed to the regularly-patterned matrix that looks more like a heat treatment or crackling effect....?)
