This one’s for the thrill-seekers. Raku Glaze is your partner in crime for experimental firings—just be ready for unpredictable, yet stunning, results.
USAGE
The Chrysanthos Raku Glaze range are a series of glaze varieties aimed more at
the sophisticated user looking for unpredictable and exciting effects ranging
from very matt to glossy variable surface textures. These glazes produce more
striking results due to their compositions, the method of firing, and, finally,
reduction.
APPLICATION
Raku Glazes are available in liquid or powder form. For the liquid, generally, 2, 3, or
4 coats may be applied to bisque. For dipping, a glaze slurry with an SG of about
1.4 is sufficient. The number of coats applied or the length of time dipped will
affect the final result, as will the firing and the eventual reduction in foreign
matter like sawdust, leaves, etc.
Once applied and dry, the glazed piece is then fired in an electric or gas kiln. Once
the kiln reaches temperature and is off, the kiln is open while red hot, and the
piece is transferred to a metal container containing organic material like sawdust,
leaves, etc. The lid is then put on the container to create a reduced atmosphere.
Flames will develop in the metal container, and a lot of smoke will follow. The
flames will cease soon after the lid is put on the container, and the piece should
be allowed to rest there until it cools down.Once cool, it can be removed from the container, scraped with a soft metal brush
to remove any excess material from the firing, and washed in cold water.
PHYSICAL DATA
The Raku Glazes have been specifically formulated for application to bisque-fired
clays that are typically middle for or stone ware. The Raku Glaze should be fired
between cone 010 (894oC) and cone 06 (999oC).
SAFETY DATA
The Raku Glaze range is lead-free. However, caution should be exercised in using
the Raku Glaze as they all have warning labels due to the levels of copper or other
elements in high enough concentrations exceeding threshold limits to render
them harmful.
When working with the Raku Glaze, it is important to use personal protection like
fireproof gloves, face mask and overalls.
