Recommended Method
1. Add water to mixer.
2. Agitate mixer as you add some of the clay. The slip will
gradually thicken.
Then add more clay.
Continue this process until all the clay is in the mixer and a
smooth creamy consistency is obtained.
3. Check the litre weight,
if litre weight is higher than the aim add water.
if litre weight is lower than the aim add clay.
For accurate litre weight measurement contact Walker Ceramics for a Litre
Weight Bottle and Calculation Chart.
4. Mix for 1 hour (more for multi bag mixes) then check if a
small adjustment * with Dispex mixture is
required for pouring fluidity.
* the powder already contains
deflocculents.
5. Allow slip to mature for 24 hours.
6. Reblend.
7. Sieve through an 80 mesh screen before use.
In all our slip recipes we recommend that the
maximum amount of Sodium Silicate is not exceeded.
Before making any adjustments make sure the litre weight is within the stated
limits for the body.
