Hammer Registry

[Saphirius]

I added a recipe in the Hammer Registry: Granite to Red Sand.
But when i start MC and open the world is doesnt work.
In JEI all Recipes are shown, and other recipes work.
Just Granite to sand not.
So the recipes is shown and all the others work, what have i done wrong?
I tried every hammer through but it doesnt work
here the line i added:

"minecraft:stone:1":
[
{"stack": {"name": "minecraft:sand","amount": 1,"meta": 1},"miningLevel": 1,"chance": 1.0,"fortuneChance": 0.0}
]
}
