great. Check out bulbius' stove, he gets 300C in the oven that is on top of firebox (6cm firebricks).

Thank you all for comments.
Orange: I checked the Bulbiu's white oven - interesting. I hope I can get some more out of it and push it to 200C. Now max was 170C. I will try some more modifications.

well your firebox is casted with perlite or some other insulative material? So no high temps, only if you put it near the top of the riser.

That looks beautiful! Nice build. I hope to learn to do much like this and many others here.

With the best ordinary tile glue I found in my area, it is a bit more elastic and tested up to 100C. But time will tell if it is good enough. A bit problematic can be big tiles of 60x30 cm size it would be safer to use smaller format. For now it seems fine... |

-you can lower the ISA by puting insulation on inside the bell If I'm using Geopolymer lining inside my bell, will this also lower the ISA? By how much? |

I’m not positive about how to calculate this, but I think it will depend on how insulative your mix is. Is it very heavy when it is dried? For example comparatively with a red brick and a similar size of your geo polymer.

For example comparatively with a red brick and a similar size of your geo polymer. Karl said this: The LTGS mixture has a relatively low thermal conductivity of about 0.3W/m*k similar to underfired bricks.

0,3W/mK and lower is considered insulation so I guess it will increase the ISA but not like vermiculite, calcium-silicate or ytong, they have lower thermal conductivity. Depends on the thickness of insulation too.
