Elements such as colors, glaze materials and tile biscuit are in second grade of quality. Drawing objects is normally print and coloring objects in the design done by hand in professional way, so in the output from the oven, you can find more dots or spots (compare to first grade quality) in Sq meter and also you will find the colors not brilliant or sharp enough on the glaze also you may find some acceptable mistakes in its drawing. This type of seven color tile is also good and normally used in normal places or places with more than 3 to 4 meter height (far view) because of its price but for the royal and first class customers to have luxurious interior or exterior decoration, this option is normally not accepted.
