Friends,
The halo effect was first produced by Soldner in his early experiments with
raku. It is achieved by painting a 50%/50% copper/iron wash over a white
slip
background. The ware is fired and removed at about cone 010-09 (you will
have
to experiment). Place the ware in your reduction container, allow the
material to flame and then cover to smoke. After 30 seconds to a minute
remove the cover and reoxidise allowing the flames to lick the piece a bit.
Cover and allow to cool. The technique is laden with nuance so be patient in
your experiments.
The white slip is applied over the bisque ware. You can use most any slip
formulated for bisque application but here's one from my friends at Dakota
Potters Supply in Sioux Falls SD:
Gerstley Borate-227g
EPK-454g
Flint-681g
Incidentally, Tom Clarke owner of Dakota Potters Supply builds the most
beautiful fiber raku kilns I have ever seen!
