Lowfire Liquid Slip
Georgies Blanco Cast ^04 Liquid Slip CL130CT
| This is our go-to slip body - it is similar to the original white cast but uses a different clay body. This new slip body casts faster - so watch your timing! It fits the standard clear glazes clear IN1001, & S2101, but our favorite clear to use is Duncan's Pure Brilliance.
(CL130CTG) One-Gallon jugs (or in cases of 4) of slip can be shipped by UPS. Each gallon weighs about 15 pounds.
(CL130CT) Boxes of 2½ gallons can be shipped on pallets by freight, but cannot be shipped UPS. Each box weighs about 35 pounds.

Georgies 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.

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!

CH304
Barium Carbonate
Toxic in its powder form. You don't have to use it in mixing your own slip, but it may be useful because it neutralizes sulfates that may be present in the clay or leached from molds. |

Darvan 811
Darvan is a dispersal agent, effectively used as a deflocculant in liquid clays and glazes. It helps hold solid particles in suspension in the liquid base. |

Soda Ash (Sodium Carbonate)
Acts as a deflocculant in reducing the water of plasticity in slip bodies. Increases workability and strength and reduces shrinkage. |

Sodium silicate is used as a major deflocculant in preparing liquid slip. It can also be used as an adhesive (ie, for securing insulation to the side of a raku kiln). Also known as "Waterglass." |
