@BluSunrize I was thinking about how best to improve the kiln's efficiency and a thought hit me: why not use the external heaters? Could it be possible that they could be used to improve the kiln's speed similar to the furnace and the preheaters for the improved blast furnace? If so, this would be a boon for the early-game alloy smelting enthusiast who needs tons of alloy for the wires needed to connect up machines.

While an idea, it would look kinda ugly, because the Alloy Kiln is 2x2 :V

may be prettier with the blast furnace preheaters:

i must say here from an esthetic (hope that's spelled right) standpoint that not all machines have to look symetrical at all, slapping on a single 1x1x3 on to an qubic 2x2x2 machine doesn't look bad at all

also malk's interpretation looks cool to be honest

I have no plans to implement this in the future
