Double Charge Dust Pressing

A dust pressing manufacturing process where one layer of porcelain powder is overlaid by another powder and the two are pressed into the mold together. This method is advantageous to produce a higher quality or more expensive surface using a less expensive base. It is also possible to fabricate and glaze ware (e.g. tableware) in one manufacturing step using this process. Manufacturers typically face challenges in matching the thermal expansions of the two materials, when the match is not right the tiles fire convex or concave.
