## Questions & Answers

**Q: Is this a glue ?**
A: No, I used it in plain water in the radiator to seal a cracked cylinder head. It worked great for that purpose, but I’ve never heard of it used as any kind of glue. This is a bottle of liquid sodium silicate. It turns from a liquid to a solid when heated which is why it’s often used as a sealer in automotive engines to stop water leaks.

**Q: Is this a glue for glass ?**
A: I use it for ceramic glaze suspension.  It would not work for glass glue.
Perhaps the answer lies with glass fusion or copper enameling.
