sodium silicate core binder question - The Home Machinist!

 · Sand size has a lot to do with the bond, as does the amount of binder used. Silicate cores can be quite hard and non porous with enough binder and cure time. In other words a problem for venting if too 'tight'. Your core mold sand should respond to the hand squeeze test the same way as any casting sand, maybe less tight, but not WET.

Sodium Silicate for Making Foundry ... - Budget Casting Supply

Sand is mixed with a binder to form a solid "sand core". A core must porous enough to allow gas to escape from the casting, while still blocking the molten metal. It should also be easily removed from the finished casting. Sodium Silicate is used as the binder that "glues" the sand together in cores. For example, imagine making a cannon.
