KNO__ZnO

This flux combination has KNO decreasing and ZnO increasing from A-B.
Generally this combination has produced shiny viscous glazes moving towards a matt opaque surface which has cracked and likely to peel off caused by the excess of Zinc Oxide which has a a low COE..It has also suppressed the Cobalt Carbonate allowing the Rutile to be more active.creating a more yellowish colour moving to a pale green as it has become matt. In the earlier samples the glaze has a very strong durable shiny quality Tile 5 is still shiny but has started to crawl
