This will add recipes to turn the 3 trash stones (Diorite, Granite, and andesite) into cobblestone. It also allows you to craft those 3 trash stones on a crafting table using the recipes below.

cobblestone = andesite

stone + beetroot = granite

stone + bonemeal = diorite

I made this after seeing a mod that did something similar (it only let you convert the useless stones to cobble and the recipe to craft the stones back if needed was my idea) but the mod was only for fabric and so I made this data pack to bypass any of those restrictions. I also let the mod author know I made a data pack that does it for private use along with the site that helped me do it and as a result, they removed the mod (I guess they realized the data pack route was better since it can be used regardless what mod loader you prefer to use (if any) but because they removed the mod I am unable to post there name here (the mod page is gone and did not remember to make a note of the name of the author beforehand).

Note: I tried to make the recipes cheap but usable and done is a way that makes some sense (diorite is white and thus bonemeal) but I may change the recipes later if it feels like the price is still too high (possibly make it so you craft 10 blocks at a time to use fewer resources or something). I used the website linked below to help with the creation of this data pack.

Feel free to let me know if you think the crafting price is too high for you.
