We usually use water glass and chalk paint; are there any other options?

We generally apply a pre-coated heat treatment protective coating, then wrap it with heat-resistant material, and proceed with heat treatment.

What exactly are heat treatment protectants, and where can they be purchased?

You can visit http://china.guidechem.com/trade/pdetail6033.html; it shows substances of a similar type. Care should be taken when choosing a brand, as the product listed in that link is only similar, not the actual brand to be used.
