The people I've bought it from call it glazed brick. The people who make it call it glazed brick. The masons I've hired to lay it call it brick. It comes in 4X8X2 (ish) blocks. It's structural. I'm pretty sure it's brick. > Brick to me is typically thick blocks of coarse processed clay - occasionally > with holes in it. > > Tile is a finer quality clay which can be also made into brick-like objects > (usually thinner) and is glazed on from 1 to 6 sides.

Except bricks are burnt in tunnel kilns these days, and not in piles. Faster, cheaper, better. What's not to like? (And the Romans had permanent brick kilns. They substantially more efficient, having lower heat losses. If there's demand for enough brick, they're well worth building even at low TL.) > > Since potteries have almost universally have moved to electric kilns - > because you have much more (and finer) control of the heating and cooling > cycles salt firings have become almost non-existant. As far as I know, brick kilns are almost universally gas[1] fired. It's a whole lot cheaper to operate a gas kiln instead of an electric one. I'd expect industrial scale pottery to be done the same way, for the same reasons. It's much more efficient to burn something for heat than it is to burn it for heat, make steam, make electricity from the steam, transmit electricity to where you want it, and then make heat. [1] there are probably coal and oil fired ones, too. -- David Scheidt [email protected] _______________________________________________ GurpsNet-L mailing list <[email protected]> http://mail.sjgames.com/mailman/listinfo/gurpsnet-l
