Therefore suitable for Dali stone fire board. Relatively compact, high compressive strength, low water absorption, soft texture, is a hard stone, easy polishing, good light, are often made of stone. Polishing plate is alkaline.
Granite, compact structure, high strength, high density, low water absorption, hard texture, abrasion resistance, acid stone, acid resistance, weathering resistance, good durability, long service life, which will occur with quartz crystal in high temperature, volume expansion and cracking, spalling, so do not fire,
