# Salt
Salt is a consumable type of material used to oxidise copper block types.
By using salt on a:
* Copper Block
* Cut Copper Block
* Cut Copper Stairs
* Cut Copper Slab
It will accelerate the oxidisation process, making the block progress to the next weathered state. It performs the opposite function of axe scraping. This process will consume 1 salt.
Salt
You can obtain salt by filling a glass bottle with water and using it on a lava cauldron. You will only sometimes get salt from this process.
