Sodium Silicate Supplier
Does anyone know of a source for sodium silicate (water glass) for producing co2 hardened sand cores.
It is readily available from most pottery supply stores but this doesn't appear to be the right product.
This site mentions the difference between pottery and foundry grades.
myfordboy blog and online resources: Core Making
If anyone has used sodium silicate for core production or knows where to get the right stuff I'd appreciate any advise.
Thanks
John

I ended up getting a 20 L drum of "Sodasil" from Cast Metal Services in Brisbane.
Much more qty than I needed but the price with freight was reasonable.
I haven't done much with it yet but early tests look promising.
