Specific gravity pottery

WebSpecific gravity is a measure of the density of a liquid measured in grams per cubic centimeter. Water has SG=1.0, which means that 1 cc of water weighs 1 gram. To calculate the SG of a glaze divide the weight of the glaze by the weight of an equal volume of water (i.e. weigh 100 cc of glaze and divide by 100 to obtain the SG of the glaze). WebTo be a little more exact, specific gravity (s.g.) is expressed as the ratio of grams (weight) per milliliter (volume). Water has a specific gravity of 1 because 100 grams of water has a volume of 100 milliliters. Since glaze contains not only water but solids as well, it will always have a specific gravity of more than one.

WebSpecific Gravity can be tested after the mixing time indicated in the table above. Viscosity should be tested no sooner than 12-24 hours after the batch is mixed. This allows the clay particles time to hydrolyze, or become wet on all surfaces. WebJun 29, 2024 · Today we are showing how you can experiment with specific gravity. I have on three sets of mugs, my base, my normal Matt white base glaze. So I have it at 1.56, 1.46 and 1.36 specific gravity. On top of that, we're going to cover it with this cover glaze right here at a high, medium, and low specific gravity. jeffrey neal https://fchca.org

Example Glaze weight = 125.4 grams Water weight = 75.3 grams (glaze weight 125.4 ) ÷ (water weight 75.3 ) = (specific gravity 1.66 ) Mayco glazes should have a specific gravity between 1.47 and 1.51. If your glaze is high, we recommend adding ¼ cup of water at the time and mix until the right specific gravity is ... WebYou can also weight test the glaze. 500ml should weigh about 720 grams = 1.44 specific gravity. At proper specific gravity, hold the pot under for about 20-25 seconds. This should give you a coat of about 2/100 of an inch if the pot is bisqued to proper temperature (around 1000 degrees centigrade in oxidation depending on your clay body). oya psychotherapie
