How many spoonfuls of kilnwash powder do I use per litre

The mixing ratio is 4-5 parts water to 1 part dry powder so if you are using 1litre of water you will need 200-250g of primer.

Can this be used on stainless steel for fusing?

We recommend using our Boron Nitride Spray with stainless steel moulds for an easy release
