Iron Oak
This mod aims to add several ore infused oak trees. This allows you to plant and farm ingot instead of mining them in the dark.
Processing
To create your first iron infused oak sapling you have to create iron infused bone meal.
Apply this to any oak sapling to magically infuse the sapling:
Once the sapling is infused, you will see it grow into an iron infused oak. Cutting this tree will give you iron infused logs which can be processed into ingot. But be careful if you cut this logs into planks all sparks of iron ore getting lost.
Next you have to craft a fire bowl
This allows you to safely burn the logs and collect the ashes. Burning iron infused logs inside a fire bowl will produce iron infused ash.
Now you can use water to wash the iron infused ash to receive iron shreds.
Once you have collected 9 shreds you can craft a raw iron.
Alternatively, you smelt the iron shred into nuggets.
