Mix to a specific gravity of 1.47. This glaze needs some Epsom salt added to the wet glaze slurry to keep the slurry from hard panning and to create a gel-like consistency that is easy to apply to bisque ware.
Mix these glazes (Rutile Blue, Dolly Russian, Susie Yellow, and Tomato Red) to a thin, tomato-soup consistency in the bucket. Even the shino (Dolly Russian glaze) is mixed so the slurry is on the thin side. If you dip your index finger in the mixed glaze, you should clearly see the wrinkles on your knuckle and the outline of your fingernail, but you should not be able to see any skin through the glaze. The glazes were all applied via dipping the pots shown into the bucket. Each dip immersed the pot in the glaze for no longer than three seconds total, and excess glaze was shaken off as soon as the pot was pulled out of the bucket. The pots were fired to cone 10 in a Blaauw kiln with a light reduction. The clay was Standard 306.
