and even bread dough

but if you are going to vent the kiln further than 60 ft

Sodium Silicate Pint Theme_Pets Cone 10 reduction (smaller image):Sodium silicate is the common name for a compound sodium metasilicate, Na2SiO3, and is also referred to as liquid glass. It is composed of sodium oxide and silica, and the ratio of these compounds in aqueous solution influences its fluidity. Sodium silicate is commonly used in ceramics as a deflocculant in slip preparation by neutralizing the charges of particles in the slip, allowing for more even suspension and thinning. It comes in a pint jar.
