IMPORTANT: Please note, the crafting recipe for Industrial Diamonds now makes standard diamonds, not industrial diamonds.
To create an Industrial Diamond from scratch, you need
- 1 Obsidian, Brick (block) or Iron Block
- A stack of Coal
- Compressor, and power to run it for 9 items (8 Coal Balls, 1 Coal Chunk)
- Macerator , and power to run it for a stack of items (stack of coal)
- 8 Flint
Macerate the Coal into Coal Dust:
Combine the Coal Dust with Flint to create Coal Ball
Compress 8 Coal Balls into 8 Compressed Coal Balls:
Combine with Obsidian, Bricks, or an Iron Block to create a Coal Chunk:
Compress the Coal Chunk to get an Industrial Diamond:
This process now makes vanilla diamonds rather than industrial diamonds.
Since the ingredients alone have more EMC than one diamond, you lose 96 EMC and a lot of time using this method. Only do this if you lack the ability to make diamonds with Equivalent Exchange, such as disabled Energy Condensers, Energy Collectors or the lack of finding Diamond.
