raku

Raku is truly exciting, slightly dangerous and spontaneous.  The bisque ware is glazed and then placed in the cold  kiln.  Within an hour it is heated up to 1000c  and then removed from the kiln, as if from an open volcano.

 

Heavily grogged clay fired to 1000c. Snatched from the kiln in a molten state. Plunged into an oxygen starved bin and covered in sawdust. The sawdust burns in the intense heat generated by the piece. As the sawdust burns it extracts oxygen from the oxides in the glaze (process of reduction) which then leaves  amazing metallic colouration. You can therefore influence the glaze effect, though you can't always control or predict the outcome entirely. . . .  and that is why it is such fun!
