Hi!
There are several options available on the reasonable price - common fireclays, professional refractory mortar (28% - Al2O3) and ready-to-use waterglass-based mortars.
It seems now that I'll use Hendo?s Dome Gauge (http://www.fornobravo.com/forum/f28/...idea-2573.html)
and will cut bricks on two sides, so, "horizontal" seams on the outer side will be relatively thick and the "vertical" seams should be really thin.
I've heard that waterglass is suitable for thin seams only and (sound strange for me) that is not good from the health point of view.
What to choose - water based refractory mortar or waterglass-based mortar?
Thanks in advance,
Dimitry.
PS. Have no masonry skills at all, but seems to be well educable (and self educable).
