Top: A thin porcelain tile with etched design. Bottom: The same tile with a back light. By Stephanie Osser. L3778G is an example of a translucent porcelain that will work for this.
Made using porcelain fired to cone 11+. This is a splendid demonstration of translucency. Without a back-light it is just a white slab. But the varying thickness in the porcelain determine the amount of light that passes at any given spot, thus producing the design. An example of a recipe to produce a porcelain like this is L3778D.
