Terra Sigillata

Terra Sigillata, being the most ancient means of bringing color, enhancing and sealing a clay surface, is a remarkable technique. It is made with very fine grained clays, lots of water, and a small amount of deflocculant to disperse the fine particles. The slurry must settle for 12-24 hours and the super fine particles are then siphoned off. This is a low-production item. Please contact us for stock on hand. 4oz & Pints only Click on the image at left for a PDF that you can print!

Slip Additives

These components are the thinning and suspension agents that hold the clay particles in the liquid base, so they don't all sink to the bottom. When mixing your slip, over-thinning (aka overdeflocculation) is a major concern. If you use too much of these ingredients, your greenware may be grainy, fragile, and difficult to handle or work with. Over-thinning errors often can't be corrected -- meaning your entire batch of slip, and the money you spent on the raw materials, all goes to waste.

Use SODIUM SILICATE sparingly: do not add it all at once! Add it only as needed for your slip to perform according to the tests below, in our Slip Usage Guide. If you reach the maximum amount of sodium silicate for your batch size and the slip still does not flow at the desired rate, you can add DARVAN 811 at 35 grams (1.24 liquid ounces) per 100 dry pounds or 105 grams (3.7 liquid ounces) per 300 pounds of slip mix.
Remember: you can always add more, but you can't take it back out!
