Na2SiO3—comes as a liquid—used as a deflocculant in slips, as an air-setting binder for low-temperature refractories. Many clay artists use it in “magic water” in place of slurry for joining wet or soft leather-hard ceramic forms. Add 1.5% sodium silicate and 1.5% soda ash by weight to a measure of water. Toxic in ingestion. Skin irritant. Source: Clay: A Studio Handbook
