I was looking for ways to stop water leaks, and I have found this interesting.
Sodium silicate has some uses that we could profit fo!

I just do not know if the temperature of 810 °C maxi is high enough, because then it will melt.

How great it would be, as it can bind vermiculite, any cement (clay??), stop leaks, repair metal leaks too.
It protects from fire and is waterproof.
It is natural, non toxic and cheap.

Xisca N: To answer your Question from your Header/Forum Thread - The various compounds that can be found under the category 'Water glass ' will seal off the pores in the cob , retaining water, Not what we want there, if used for repair due to the high rate of expansion , you will have the same problem that you have trying to use metal mass in the Rocket stove different expansion rates, where you probably have the best results will be where you make up individual parts like a separate Heat Riser that you bake in place and then use as part of a R.S.M.H. Build at a later date .

I to wish the temp could be just a little higher ! PYRO Allen L.
It's just a flesh wound! Or a tiny ad:
