Modding Help Modifying Recipe's requirements

Heya,

I am creating a mod where I would like to add more recipes for "Artisan Equipments" and "Refining Equipment".
For example, I would like to :

1. change requirements for crafting "Cloth" with the "Loom" (not only depend on Wool)
   
   
2. add new objects to craft with the "Furnace"

I've been thought this guide : APIs Content, but I can not find what I need.

I understood how to alter objects with the StardewModdingAPI.IAssetEditor class, but which asset ?
So far, I have looked at these assert categories:

• Data\CraftingRecipes,
• Data\ObjectInformation,
• Data\BigCraftablesInformation.

But there is no information about the "crafting" requirements for "Artisan Equipments"or "Refining Equipment".

Any help?

Thank you so much,
Best,

Thomas
