M2 vs. Redart
Tuesday 22nd April 2014
Plainsman insight-live.com/material/2249">M2 (left) vs. Redart (right). These bars are fired cone 04, 02, 2, 3, 4 (top to bottom). Fired color is almost identical. M2 has a little more soluble salts (however M2 has no chemical additions to precipitate them, it is ground as the pure mined material). M2 is more plastic (although still not as plastic as a typical pottery clay). However, Redart will make a good casting slip while M2 does not respond to deflocculants.
