Raku Firing is one of my favorite types of firings I have
learned because of the many different processes, glaze adjustments and
tinkering you can do to obtain a result that can be surprised by. Since the firing time is short, I fire my
Raku pieces multiple times.
This series was fired with a Copper Matte Stain (80/20).
Usually the firing temperature for copper Matte is lower than that of the average range; I fire the first firing to
the latter and quick cool it in a water bath,
Re-glaze the piece in a Copper based Boron fritted glaze and fire it for
a second time slightly hotter than the mean Raku range.
My base for the Copper Luster Base mainly consists of two
raw materials and a precise copper oxide measurement and variations of added
secondary oxides such as iron oxide or cobalt.
When the matured piece is reduced in combustibles, the initial ignition
creates degrees of reduction unique to each piece.
These pieces are beautifully flashed with a rainbow of rich
metallic lusters. I especially
appreciate the rich deep crimson and a range of blue to blue green hues. This series is rustic and the textures in
places and silky smooth in other rather organic.
These are purely decorative and are made to be admire to the
point you can’t help but to want to pick the piece up so you can feel and look
at the many different angles and faces as they change in different sources of
light.
