How to Test Viscosity of Duncan Pure Brilliance Clear Glaze Be sure to test the viscosity of your clear glaze before when opening a new batch and before each dipping session. Since some areas are more arid than others, you may find that checking the viscosity periodically during a dipping session is necessary for your environment. 1. Thoroughly mix the glaze. 2. Let bubbles rest before testing viscosity. 3. Submerge the Viscosity Cup (#TL497) into the dipping tank and fill with glaze. 4. As you lift cup from glaze, begin timing with a stopwatch. A stopwatch provides a more accurate count than a second hand on a clock. 5. Hold cup approximately 6" to 8" over the glaze 6. Stop timing when the steady stream of glaze begins to break. 7. Pure Brilliance viscosity range is 19-24 seconds with 20-23 seconds being ideal. A viscosity of 18-23 seconds is normal with other Duncan clear glazes. 8. Add small amounts of water 2-4 ounces of distilled water at a time, as needed. | To buy a Viscosity Cup, click here. To buy Duncan's Pure Brilliance Dipping Glaze, click here. | |
