SIO-2 PRAF White Sculpture & Raku Ceramic Pottery Clay | 4 lb, Cone 6-10 | High Fire Kiln-Fired Clay for Wheel-Throwing, Hand Building, Modelling - Create Pottery and Sculpted Artwork, Ready-to-Use

I purchased this small package of raku clay for a summer “art teacher camp” I will be attending. We have to bring a piece to raku fire and I did not have any appropriate clay at school. While the price point and size was great for what I needed (I threw three small sized bowls/cylinders) to trim, the clay itself is EXTREMELY course and not fit for throwing, in my opinion. Before I had even finished throwing the first bowl, it had acted like sand paper and I ended up bleeding all over the place from my hand. I forced myself to throw the last two pieces so I wouldn’t have to endure it again, but I also ended up with micro abrasions on my fingertips. I switched to using a sponge as I attempted to pull the clay up, but it was not very flexible or fluid on the wheel. It has been a while since I’ve thrown, but I never had issues like this when I was learning or when I used a hand-made raku clay in college. I have not trimmed these yet, but I am worried that the grog is so big, that I may take chunks out as I trim. I plan to fire at 05 as per the instructions. I highly suggest using this raku clay for hand building only.
