Spectrum Oxide Pens
Spectrum oxide pens in the same easy to use
applicator bottle as the RAC’s and SuperWriters. These oxide pens
contain various oxides, such as copper oxide, cobalt oxide, etc, suspended in
water with small quantities of additives such as frit which improves their
performance. The perfect solution for studios, schools, and community
centers that want to play with oxide decoration but have a “no dusts or
powders” rule. The liquid oxides can be used in the writer / applicator, or
can be
brushed on.
Spectrum oxide pens give particularly interesting results when used on
pieces that are raku fired, but they can also be used in a regular kiln.
They've been tested to cone 6 with good results. Although not tested, it
is expected that they will work up to cone 10. (Let us know :-)
