This machine is used for testing whether ceramic utensils happens any changes in gloss or color due to detergent attack, that is mechanical dish-washing resistance of utensils.
During the test, it mainly adopts that unused specimens are immersed in a static solution of a specified alkaline dish-washing detergent at(75 ± 1) °C for a total of 32 hours test principle to measuring the dish-washing resistance of utensils. After test, the specimens are then examined visually and compared with similar, untested pieces to determine any changes in gloss or color resulting from detergent attack.
