Smeltery
The Tinker's Construct Smeltery is a variably sized multiblock structure necessary to progress in the Stone Age. It's primary use is casting basic metal parts before the MV Extruder, mass-processing dusts or ingots, recycling metal items and solidifying glass blocks.
How to Build
The Smeltery can be built with any footprint from 1x1 up to 11x11. To be a valid structure the interior must be a square; same length and width, with any height of one or more. The bottom layer can be anything tagged as 'smeltery structure block' in NEI. The Controller must face outwards, its back touching the Smeltery's interior. At least one lava holding block (Seared Tank, Seared Glass or Seared Window) must be on the same y level as the Controller.
Usage
The speed of the Smeltery is constant based only on the type of material being melted. While melting anything, it consumes Lava at a rate of 30L/4s. Number of items being processed does not affect the Smeltery's fuel consumption, thus a larger Smeltery is more efficient as the number of simultaneous items is equal to one per interior block volume.
