groups

{
    "groups": [
        "fabric",
        "metal",
        "my_custom_group"
    ]

Modules check for groups to see what materials are allowed to be used for crafting

icon

{
    "icon": {
        "type": "item",
        "item": "minecraft:sculk"
    }
}

Icons are rendered in the ui as a short-hand for the material. we heavily recommend the usage of the item type Alternatively, direct texture can be used too

    "icon": "textures/item/kelp.png"
