Decopot
Soda Ash Dense (Sodium Carbonate)
$95.00
Commonly used as a soluble deflocculant in ceramic slips and glazes, soda ash works well in combination with sodium silicate to produce body slips that do not gel too quickly and whose rheology can be adjusted for changes in the hardness of the water. Higher soda ash proportions (vs sodium silicate) will produce a slip that gives a softer cast (stays wet longer). The total soda ash and sodium silicate amount should be tuned to create a slip that will eventually gel if left to stand. This thixotropic behaviour will prevent it from settling. Sodium carbonate is also the preferred deflocculant for thinning glaze slurries.
