Is your feature request related to a problem? Please describe.
In TFC, the stone blocks have a very high hardness index, which is why GT picks and GT mining hammers dig the TFC rock for too long. I would like to have a hardness setting for GT ore using Crafttweaker.

Describe the solution you'd like
Have a ore hardness setting via crafttweaker.

You can set block hardness already with crafttweaker https://docs.blamejared.com/1.12/en/Vanilla/Blocks/IBlockDefinition
