With a dutch oven I was able to boil water in  20 min, then rolling boil in 30 min.

Having the cement pot skirt helps, but there seems to be a sweet spot for the space between the pot and the cement wall for most flow / heat getting on pot.

Those flames are impressive!

How the ceramic fiber and glass water feed holding up?

Got an idea about forming a blanket into a one piece J and coating it in water glass adding a 5 min riser?

You mentioned in another post you could see the ceramic fiber glowing from the outside?

So thicker than 3/4 inch is needed I'm guessing?

Edit sorry one more question!

Looks like you used cement sealer? Is that pure sodium silicate? Struggling to find tech  sheets for stuff over the pond

Thanks for all the posts!
