N40 Dispex
In a 30 litre container place 11.4 litres of water.
Add Sodium Silicate mixed with 200 mls of water.
Agitate as you add the clay.
Check litre weight is 1750 grams/litre. If litre weight is higher than 1750, add water. If litre weight is lower than 1750, add clay.
Slowly add Dispex mixture (20 grams diluted with 40 mls of water), as required to maintain good mixing fluidity.
Mix for one hour then check if more dispex mixture is needed for pouring fluidity.
Allow slip to mature for 24 hours before remixing, sieving through an 80mesh screen before use.
Makes approximately 20 litres of slip at 1750 grams per litre.
