Plainsman H550 Cone 8-10 Grey-Buff Ceramic Clay Body, 10 kg

Plainsman H550 Cone 8-10 Grey-Buff Ceramic Clay Body, 10 kg

High temperature, slightly sandy, plastic, semi-vitreous, grey-buff burning, general purpose, native body for reduction and oxidation fired functional stoneware. H550 has a fairly plastic but slightly sandy texture and generates plenty of slip during throwing.

H550 is fairly vitreous at cone 10R (the most mature of Plainsman’s bodies made completely from their materials). H450 is slightly less mature and a little more stable in the kiln, it is also smoother, cleaner and lighter burning. In oxidation H550 burns to a much lighter grey buff than it does in reduction. Since H550 contains some free silica, normal care is required when heating and cooling it through quartz inversion temperatures, especially if ware is being refired.

Since H550 contains more than 70% SiO2 you can expect it to accept most typical cone 10 glazes without crazing them (glazes which craze on porcelain bodies will often fit well on H550).

Proudly Manufacturered in Canada by Plainsman Clays.

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.
