The Hydro-Bat is made of Hydro-Stone, a USG product containing cement and crystalline silica, that is 8 to 10 times stronger then pottery plaster. The surface is scratch resistant yet absorbs water like plaster eliminating the need to cut your pieces off the bat with a wire. The 8.5" Hydrobat is perfect for production of small cups and bowls. The smaller size make them light weight and easy to store away when not in use. The rubber grommets are spaced 6" apart allowing Hydrobat to fit perfectly on a 10" to 6" adapter. All Hydrobats are made from hydrostone plaster to absorb moisture like regular pottery plaster but with extra strength to prevent chips and cracks for those of us with butterfingers. This product needs a 10" to 6" adapter to fit on a standard wheelhead with bat pins spaced 10" apart.
