Plainsman L212 Cone 06-6 Cream Ceramic Clay Body, 20 kg

Low temperature, smooth, medium plastic, light cream to grey buff burning, refined talc earthenware. L212 is a mix of Plainsman's native stoneware clay, A3, with talc, ball clay and bentonite. It is a popular body for use in schools.
To retain plasticity (to tolerate the talc addition) about 10% of a ball clay bentonite is added to the mix. These additions give the body a very pleasant, smooth feel for throwing and modelling forms of all shapes and sizes.
L212 dries fairly quickly with minimal cracking. However, it is fine-grained grained so good joining practice is still important.

L212 is almost always used at cone 06-04 with commercial bottled glazes. The body color darkens to a yellow buff by cone 2, then to a grey buff by cone 4 and above. If glazes can tolerate it, denser stronger ware can be made at cone 03 or even 02 (while the ware is stronger, like any earthenware body, it does not vitrify at low temperatures).

L212 contains 30% talc. This significantly increases the thermal expansion of the ware (when heated) and thermal contraction during cooling. That contraction squeezes the glaze onto the ware and helps prevent crazing. The percentage is tuned so that most glazes fit.

Storage: Protect ceramic clay bodies from direct sunlight, avoiding excessive temperature changes and protect from frost.

Use: It is recommended to test clay body prior to large scale use in order to verify suitability in both the ceramic process (shaping, drying, firing and decoration) and the final application that is expected to be obtained.
