the kolkon smelter 1: 1.5 items per second, 20 iron / furnace
includes fuel indicator light, and automated deposit/collection
this is one of six smelters i'm building. depending on how many items there are to be smelted, the number of smelters used can be adjusted to optimize lava bucket usage.
full capacity should smelt 2.5 large chests in < 17 minutes using 140 lava
and i'm building this because i get mad at the inefficiency every time i run around like a headless chicken while manually operating 92 furnaces
