If you are mixing your own pottery glazes one of the challenges to get the right mix between dry materials and water - and to end up with a glaze that have the right viscosity so the perfect layer of glaze materials is left on your pottery.
There are several ways you can measure pottery glazes. In this video I will show the 3 most common ways to do this.
The most accurate way to measure pottery glazes is using Specific Gravity. Many think this is too geeky and difficult. But it does not have to be.
In this video I will show you are very sime, easy and cheap way to measure Specific Gravity for your pottery glazes and how you can adjust them to get the right viscosity using fluctuation or de-fluctuation materials.
