WebJun 30, 2024 · Mix up a couple hundred grams of base glaze with enough water to get it to 1.5 sg. dip a test tile once (count the seconds off) then when the sheen is gone dip the top half of the test tile a second time. Add a small amount of water and measure the sg again and dip another tile. WebSpecific gravity is controlled only by the ratio of water to dry material and is independent of viscosity, which is a measure of how fluid a material is. ... However, since ceramic materials vary in viscosity, a hydrometer will not sink consistently. Also, they are a combination of expensive and fragile. SG is a ratio of the density of the ... drum backtracks for guitar
