Bronze Plated Blast Furnace

The Bronze Plated Blast Furnace is part of a GregTech multiblock structure with dimensions 3x3x4. This multiblock will allow you to manufacture your first steel.

This functions very similarly to the Railcraft Blast Furnace but is built slightly differently.

One Iron ingot and 4 Coal/Charcoal will yield 1 Steel ingot and 4 ashes when processed by the Bronze Plated Blast Furnace.

Building the Multiblock
The base of the Bronze Blast Furnace is 3x3 and the height is 4 blocks. The base consists of 9 Bronze Plated Bricks.

All layers apart from the base are hollow.

The second layer from the bottom is made from 7 Bronze Plated Bricks and 1 Bronze Plated Blast Furnace. The Bronze Plated Blast Furnace must not be in a corner.

The third and fourth layers from the bottom are made from 8 Bronze Plated Bricks.

In total you will need 32 Bronze Plated Bricks and 1 Bronze plated blast furnace (2 stacks of clay balls, 32 cobblestone, 6 stacks + 8 bronze ingots). You will also need some hammers and wrenches.

An easy way to know if you built the structure correctly is to place 1 iron ingot in the top slot and 4 Coal/Charcoal in the bottom slot of the Bronze Plated Blast Furnace. A lava source block should appear in the middle if the multiblock structure if you look from the top.
