5 lbs. Color Slip Cone 6-10
Description: Color Slips are porcelain based slips that can be used under glazes in both reduction and oxidation firings. Color slips are great because you're able to get an amazing variety of different results using the same clay body and glazes. Just by spraying (or dipping) a color slip over your work gives you an entirely new palette of color to your finished work. We know this slip works over Coleman Porcelain. And, Coleman Porcelain has a wide range of firing capabilities including mid-range oxidation. One order equals 5 lbs. of dry slip. Makes approx one gallon of liquid slip.
Mixing: Add water and screen twice thru an 80 mesh screen. Have the slip at 48-50 on a hydrometer.
Application. Color slips can be dipped, brushed or sprayed. If you'd like to brush them on you can add about 1 teaspoon of liquid glycerin to about 2 ounces of slip or glaze. It makes it heavenly to brush on. To dip (or submerge a piece completely into the slip) you'll need to low-bisque fire the work before. (about cone 010-08). Then, have the slip at about 48 or thinner (46) on the hydrometer. After the slip is dry on the work check it and see if the slip has cracked on the surface. If not - it's a good application. To spray on have it at 50-52 on the hydrometer. Can spray onto bone dry greenware or bisque ware that's been bisque fired to cone 010 or 08. About 2 to 3 rotation sprays.
Firing: Ranges from cone 6- cone 10 in reduction or oxidation with a slight color variation.
Image info: The Weed Bottle has Blue Slip with revised Kline Crystal Reduction glaze. The Red Slip test tube has Multi-White Glaze and was fired to cone 10 reduction. The variety of color slip times has Ash Glaze and were fired to cone 10 reduction. Oxidation firings have only a slight color variation. Your finished color will depend mor upon what glaze is applied over the color slips.
Note: As with any unfamiliar slip or glaze you'll want to run some tests before you apply it to lots of important work.
