 My dome's gone white - HELP!
I know your dome's supposed to go white with the right heat - but when I looked into my cool oven today and saw white mortar joints looking like cracks I nearly panicked!
I scraped at a few of the 'cracks' with my pointing trowel and fine white powder fell out. In some cases I could almost see the insulation blanket at the end of the empty joint :-)
Hendo, I believe, related a similar thing some time ago; have to search for the thread...
In the meantime, I worry about the entire structure: did the Airset mortar premix from Darley Refractories in Melbourne just turn into powder trickling out of the joints?
It's enought to cause a fella to turn to drink, so I opened a nice bottle of Tahbilk Marsanne to console myself - and contemplate the possibility of having to re-point the entire dome (from the inside, at least) with some seriously sticky hi-temp mortar...
Helpful suggestions welcome.
Cheers,
LMH
