A stoneware temperature body becoming very dark and highly speckled due to high content of dark burning trachyte dust as part of the grog content.  Remainder of grog is crushed firebrick.  All grog content is minus 16 mesh.  Like the Red Raku, the Buff Raku is plastic enough for throwing if a grogged clay can be handled.  Suitable for addition to stoneware clays for grog content, texture, specking and colour. Suits larger pieces, handbuilding, sculpture and Raku firing.  Fires buff at earthenware temperatures to deeper brown at 1300°C.

(NB beware trachyte particles fluxing onto kiln shelves at high temperatures - batt wash shelves well!)
