 Before Firing |  After firing to Cone 5 |
I normally fire to Cone 6 (around 2,300 degrees F) or Cone 04 (around 1,900 degrees F) if it's a bisque/low-fire glaze. We use glazes that range from Cone 06-6 - those formulated for that full temperature range typically lose some of the color brightness/intensity achieved at 06, when fired to cone 6.
With this in mind, we tried firing to cone 5 (with specific cone 5-6 glaze) to see if we would retain more of the "published" glaze color - and while some did not show much difference, others did not impress at all.
As a result, we're re-glazing and re-firing to cone 6 today. Some will have additional glaze added to achieve a truer color, some will have different glaze added (because the original result was "ick"), and others will just be put back in to fire again - hopefully to achieve the color desired in the first place.
While Pete is convinced that "reglazing doesn't work", we have had some success in the past. I'll show before and after pictures either way!
