Matt will show you how to make white earthenware casting slip from a 25 kilo sack of dry pellets. How many items can you make from a single bag? www.hobbyceramicraft.co.uk/ea...
I find sodium silicate works more effectively. The dispex is a blend of sodium silicate and soda ash, which balances the deflocculation preventing a cast being too brittle with sodium silicate alone.
Are your moulds dry? A wet mould can cause air bubbles in cast items. Check your s.g. is low enough and don't be afraid to use deflocculant to dcrease the viscosity.
@@HobbyCeramicraftit’s in the slip unfortunately… i get the sg right but i can’t get rid of them. Even bought a few different attachments for my drill and tried mixed on the lowest..
hmm.. not sure.. we get them from colorobbia in Italy, you could ask them directly, I know they sell glaze to USA. Most likely you should be looking at a domestic clay supply, there is surely an alternative clay available a lot closer to you than Europe..
