The Cone 4/6 Shino glazes are all lead-free and dinnerware safe. 
Some have a Health Label due to the presence of zinc or copper. 
They require 2-3 coats for full coverage. 
At Cone 5 the shinos produce a satiny matte finish. 
When fired to Cone 6 they become glossier and the breaking effect of the colors become more pronounce.
