Smelting arrays for ore and bricks. Includes a few variants, ranging from easiest to construct to most compact. I created all of these designs based on other people's early game books.
In each case I:
- downgraded to the cheapest materials (red belts to yellow belts, blue inserters to yellow inserters, medium power poles to wood poles)
- added or removed furnaces to consume all the inputs or saturate the output
- made the blueprints tileable
- straightened out the wires
