I use Duncan CC on greenware. I glaze with Gare or Mayco. Often after final firing, the red, purple or orange areas look as though the clear glaze "skipped" or just didn't take. Is my underglaze old? Is there an expiration date for underglaze? Is my underglaze somehow contaminated or something? Why only red? Please help!!!
