Raw Mats - Fall 2008 - Carlo Sammarco - NYSCC @ Alfred UniversityFor the third and final round of tests, I did a color run using point 7 from test 1 with a 1 percent additionof CMC. I added in increments of 1, 5, and 15 percent: Crocus Martis, Cobalt Carbonate, Dark Rutile,Copper Carbonate, Mason Dark Red stain, and Mason Sage stain. The tests for reduction yielded someinteresting results, but perhaps even more interesting were those for oxidation, as the kiln under firedand only reached cone 5. A few of the surfaces had the orange peel texture I was interested in. It isinteresting to note how some of the surfaces became a little glossier and smooth due to the colorantaddition acting as a flux, while others acted refractory and produced a more matte or pockmarkedsurface.Results from test 3:42
