Results indicated the following.1.No color differences were found among specimens of individual batches.2.Discerning color changes were observed among three batches of one brand of porcelain.3.The porcelain fired in the laboratory may not match the manufacturer's standard shade guide.4.Batch to batch variation of porcelain may necessitate the fabrication of customized shade tabs with fresh batches of porcelain.
