Low Fire Clays

Low White
This is a smooth, all-purpose talc body which fires very white. It has been designed to accept most commercial low-fire glazes and to stand up to abuses of the classroom. Low White is also used a great deal by mold makers to make models because of it smooth texture and low shrinkage.

02-20 & 02-20G

This clay has been designed to feel more like a smooth stoneware than an earthenware body so it is used most often by throwers working in low fire. It does not contain any talc. The grogged version contains 5% 30-80 mesh grog and both clays fire quite white.

PHB & PHB-G

This body fires pink-brown at Cone 06 and a little darker at Cone 04. This smooth, slightly sticky body is for handbuilding and throwing and accepts commercial low-fire glazes. It is used extensively when plasticity must be retained over a long working period as in children's programs. PHB with grog contains 5% of 30-80 mesh grog and is used for larger pieces. Both versions are extremely good dryers.

Low Red

This body fires a darker red than PHB and has a smooth, clean surface. Low red is used more as a throwing clay although many of our customers use it for hand building. It is a much stronger body.

Red Majolica

This body has a strong red colour. When fired to Cone 04 it will be as durable as most stoneware clays. Originally designed to provide an excellent backdrop for majolica decoration, this body provides a solution to the dilemma for making truly functional ware at low-fire temperatures. It is formulated for higher expansion/contraction to counter crazing.

Mid Cal Grogless

Back to top

Mid Cal 5

This body is similar to Mid Cal Grogless with the addition of 5% of 30-80 mesh grog for those who like a clay with tooth. This aids in the production of large work and ease of drying.

Back to top

Dark Mid Cal 5

This body is very similar to Mid Cal 5 but fires to a darker brown colour at Cone 6 oxidation. The higher iron content helps some glazes to develop richer shades.

Back to top

Mid Red

This is a fairly smooth body with a 5% of 30-80 mesh grog for some tooth. Mid Red is a very responsive throwing clay which fires to a strong red colour.

This is a good compromise between stoneware and porcelain.

Raku Clays

White Sculpture/Raku

This is a coarse handbuilding clay which was originally designed for large sculptures. It contains 25% of 30-80 mesh grog so it is suitable for pieces with large cross sections. It does not contain any fireclays so it fires quite white at Cone 05 or in raku. At Cone 10 reduction it is a strong grey and in oxidation it is a grey-white.

Self-Hardening Clays

Mexo-Red WC-640 &
Mexo-White WC-641

Suitable for throwing, coiling and sculpting. Allow for some shrinkage. Uniform thickness is desirable and may be achieved by hollowing out sections of greatest mass. To maintain workability, store Mexo in an air-tight container until work is completed. Air dries quite well. Do not fire! Finish with acrylic paints.
