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.

If anyone has used sodium silicate for core production or knows where to get the right stuff I'd appreciate any advise.
Thanks
