What about Sodium Silicate?

So I'm going to rebuild my RMH this off-season. Was going to substitute the firebricks with either castable refractory cement or maybe even try ceramic sheet.
Then two weeks ago I watched several YT videos where people made forges using a mixture of perlite/aluminum oxide/sodium silicate.
Here's one: https://www.youtube.com/watch?v=vQN7EqGMTuo
That mixture looks to be even more insulative than our standard perlite/fire clay/furnace cement mixture. And it appears to be harder as well. Anyone tried this sodium silicate as a binder for a core or a heat riser?
