Steve,

I have a recipe for a glaze called Kev's Copper Red Raku which produces the
most pleasant turquoise blue colour in an oxidised firing. I know you
really wanted a blue for reduction but I thought that you may be interested
in this one anyway.

Kev's Copper Red

Frit 4508............90%

Kaolin...............10%

Tin...................5%

Copper Carb...........1%

The recipe states that it is best oxidised but I have also had some
interesting results when used in combination with other glazes in a raku
firing.
