GROUND GREY GROG 0 TO 0.1 MM – 25 KG BAG

Ground fired clay with a very fine particle size (0 to 0.1 mm), grey in colour.

Added to clay bodies, it reduces shrinkage and the risk of cracking during drying and firing, improves the handling of pieces and their resistance to thermal shock, while maintaining a smooth surface.

Generally incorporated at 5 to 20% depending on the application.
