<p>Many years ago I glazed a large pot with a white matte glaze in wide alternating stripes with a chrome green. It was reduction fired to cone 10. I believe some of the chrome fumed off and was absorbed onto the white, turning it to a beautiful pastel pink. Fume effects have been widely reported over the years with many effects possible.</p>

<p>My brightest Pink is produced by a glaze with Tin, but has not even trace amounts of elements which are reported to create pink when combined with tin, such as chrome or manganese. The glaze does have a very high concentration of Boron, from the 3134 Frit which could be reacting with the tin to make pink? Typically high Boron levels are reported to inhibit pink colors.</p>
