Spectrum Hi Fire Glazes
 

Hi. Has anyone tried the Spectrum Hi Fire Glazes (1200 series)? What has
been your experience? I know that they are a little pricey, but I only plan
on using a small amount to decorate some pieces which will be fired in a gas
kiln with very light reduction. In particular, I am looking at the Ruby
(1215) and Purple (1241). Thanks. Rick
