From Vintage Story Wiki
There are lots of blocks in Vintage Story to learn about. However many of them share similar characteristics that control how they behave in the environment and when you interact with them.
Common Block Behavior
Replaceable
A value usually between 0-9999 that indicates which blocks may be replaced with others. Any block with replaceable value above 5000 will be washed away by water. Any block with replaceable value above 6000 will replaced when the player tries to place a block. Examples: 0 = Bedrock, 6000 = Tallgrass, 9000 = Lava, 9500 = Water, 9999 = Air.
