Yet Another Day at the Office . . .
Had the opportunity to spend another afternoon where it's hot as
Hades. This time it's in living color!
First two are of a glass casting operation. The following eight are of a
dramatic and skin scorching procedure to change out a ceramic pot inside
the 2,500F furnace! Molten glass is very corrosive to just about
everything it doesn't immediately ignite into flames. The replacement
ceramic pot is pre-heated for four-five days in another furnace to get it
up to 2,000F. Then, without shutting down the main furnace, its firebrick
wall is broken out and the two are switched, after which the wall is
bricked back up.

BTW, a 1/2-inch steel batten is lowered to block the hole as it's torn out
and while the forklifts are moving the pots around. I asked how many pot
changes the batten lasts before it must be replaced. Reply: six to eight
before the heat eats through it.
