Starting on Vulcanus I've noticed, I need more stone than I get as byproduct. Instead of building a buffer or fixing my factory, I've made this mod as my first one.

This mod adds various stone-related recipes locked behind techs.

Lava to stone (tech)
- unlocks the recipes for stone, stone bricks and walls
- unlocks stone to lava recipe (optional in settings)
- unlocks next tech

Lava to concrete (tech)
- unlocks recipes for both normal and refined concrete
- unlocks next tech

Lava to foundation (tech, optional in settings)
- unlocks Vulcanus recipe for foundation
