Western Raku is black due to carbonization from the secondary reduction. Western Raku and the Japanses Red Raku ware are both porous. This gives poor thermal conductivity, ideal for holding tea; it also gives a strange quality to Western Raku because the objects often feel lighter than one expects, as the clay is not fused. Curiously neither Japanese nor Western Raku glazes are very well balanced from a chemist’s point of view; the decorative appearance and tactile qualities are considered to be more important (Jones
