This Minecraft Fabric mod adds slab and stair variants for the following blocks:

iron block
gold block
diamond block
emerald block
coal block
netherite block
lapis lazuli block
obsidian
bedrock
calcite
quartz brick
end stone (not end stone bricks)
concrete (all colors)
terracotta (all colors)

Slabs and stairs from this can be crafted just like vanilla slabs using the crafting table, and with the exception of bedrock, they can also be crafted using the stonecutter.

Coal slabs and stairs can be used as furnace fuel. Each coal slab smelts 40 items, and each coal stair smelts 60 items.

In addition, this mod allows a quartz block to be crafted into 4 nether quartz, allowing quartz blocks to be used as storage blocks similar to other mineral blocks.

Both vanilla slabs and stairs can be crafted into their base blocks as follows:

Four slabs arranged in a square produce two full blocks.

The mod is available in the following languages:

English (US, UK, Canada, Australia, New Zealand)
Spanish (Argentina, Chile, Ecuador, Spain, Mexico, Uruguay, Venezuela)
Portuguese (Brazil, Portugal)
French (France, Canada)
German (Germany, Austria)
