ROSEVILLE CEDAR HEIGHTS (ROSEV) Minimum order quantity is 10 lbs.

History:
In the mid 80's, Cedar Heights' Goldart was full of sulfur and iron. We
worked to improve that, which we did, but wanted to look at other options. We
looked at the #3 from Roseville, and found it to be very low sulfur, very low
iron, a bit shorter in plasticity, and lower firing temperature. It cost a bit
more because it was 90 miles away, but was a great clay. We ground it straight
to a 200 mesh. Steve
