Two Birds

I was busy cleaning up the yard yesterday, trying to figure out ways to reduce clutter around the studio, and had an epiphany.  I could take all of the old electric kiln back up brick that I’d gotten hold of 7 years ago and lay it over the fiber layer on the wood kiln before covering it all up with more mud.

It was a quick, easy decision to make, and actually a quick, easy job. Finished it up in about one half day, and it should add a lot of insulating power to the kiln shell. Best of all, I no longer have a huge stack of orange crates filled with brick, covered with corrugated steel sheeting, sitting at the entrance to the property!

After all, and this is the eerie part, I finished the whole chamber with only a few bricks to spare, plus some unusable fragments. So, the left over brick pile, formerly home to numerous leeches and centipedes, and a few snakes, is now a nice extra layer of insulating brick on the kiln. In truth, the kiln looks like crap now with all of those different bricks sort of jigsaw puzzled on there, but once it has its nice mud jacket on, it will be spiffy and clean looking once more.

The first ‘test’ section.

 Continuing to the other side…

 All the way to the front, both sides, and the bricks are pretty much gone.

 You can see here the mix of bricks, B-1 and C-1 backing brick, and a few inner hot face brick with element grooves. Door lintel areas have some mud/rotten granite/straw mixture to support the bricks. Lots of room left around doors and peepholes to allow a nice thick edge of mud later. The mud mixture is really great, only shrinks 3% from wet to dry, and holds together like cement. Best of all the company will deliver it for about $80 for one ton, or $120 for two tons. It is originally made to be the under layer for roof tiles on old style tile roofed houses and temples/shrines.
