How to make custom furnace recipes

[bigbaddevil6]

I was wondering two things. 1 how do I make a furnace recipe that is only used in my furnace I specify? 2. How do I do the recipe for a furnace that has 2 input slots? example: coal & diamond are required to get the output

1) Create a new FurnaceRecipes for your custom furnace, and register it to that.

2) Create custom settings for your furnace if you want to change the inputs, look at the vanilla Furnace.
