Holiday Gift Guide 1kg Spodumene Substitute Set [4qfyA8C1]

A spodumene concentrate substitute from Laguna Clay, a mineral rich in lithium. Lithia is lighter in weight and contracts less on cooling than other alkali oxides making it an effective anti-craze agent when used in substitution. It also influences glaze colour, promoting blue from copper and pink from cobalt.

For more information on spodumene, see the Digitalfire.com Reference Library of ceramic materials.
