[QUOTE="Affinity, post: 231291, member: 1246"] Make sure they are dry before you color. I use gloves to color.. We were always taught about the oils in our fingers contaminating metal, so why would they not affect a porous material like green zirconia? and not allow the color to penetrate on the surface. Probably not what is causing your spots.. Did you try using a new tray also, or just new beads? My amann oven says not to mix different zr in each trays, one for zolid and one for zi. Says that white spots can occur. [/QUOTE]
