Lava Furnaces
This mod completely transforms how furnaces operate by adding a completely new method for their functioning. Now the central element becomes lava placed directly beneath the furnace.

The creator was inspired by the "Use lava from underneath" setting from Purpur, but decided to take a different approach. The main feature of this implementation is that the lava is not consumed during operation - it remains in place, continuing to power the furnace indefinitely.
If the mod is installed on the server, the client-side is not required - the functionality will work for all players automatically. This simplifies the integration of the mod into multiplayer projects.
