I got some materials from someone, one of them being labelled neph sye. It sure looks like Gerstley to me in color and feel. The bag is from Laguna. My neph sye is and has been white. Has anyone ever gotten any that looks like a ball clay or gerstley? Donna
do a button test of both side by side, that'll tell you Steve
Yes I will definitely do that before going any further with it. Mostly I was curious if it possibly could be some odd form of Neph Sye (a white/gray material not buff brown as far as I know).
My last firing I did a canvas button test of all my materials. It was fun to get that out of the kiln. In fact I liked it so much that I'm going to do it again but the next time something a bit more fancy.
I would not use any new material without testing it but I won't even trust this in a test glaze. I trust the unopened bags that have the labeling by the manufacture but this made me realize I should not trust any self labeled bag even if it did have something written a dozen times on the bag. I can't imagine why the Laguna (Californa supply company) did not have the bag labelled.
