cone 11, wood-fired
I-50 W Ditch— near Delta, UT — (39.31611, -112.57955)
date collected: 03/31/2025
I’ve yet to test this material, but it appears to be a vein of sediment with a high copper carbonate content!
I-191 W copper carb? — near Moab, UT — (38.71744, -109.70825)
date collected: 03/30/2025
I-50 W kaolin?— near Garrison, UT — (39.03637, -113.39110)
date collected: 03/31/2025
I’ve yet to test this material and am unfamiliar with wild kaolin, but the way it behaved when I dug it made me believe it has a high clay content. Stay tuned!
