Sami's Simply More Lava

The heating cauldron is crafted from four nether bricks and three iron blocks. Each cobblestone placed inside produces 1,000 mB of lava, and the block can hold the equivalent of two buckets. The heat source sets the rate: a magma block below it drops pieces of an item and plays a sizzle, and lava is generated whether the heat comes from magma or from solar heat. Its processing time has a base of five seconds, shortened by hotter heat. The block outputs a redstone signal that tracks how full it is, so it can feed other machines.

The solar heater is crafted from three glass blocks, four nether bricks and one amethyst shard. Under peak sunlight hours it produces a concentrated laser. The solar reflector, made from one amethyst block, two glass blocks and six nether bricks, redirects the heater's laser sideways, so the cauldron can be heated from one more side. Lasers reach only four blocks, and the mod notes that a reflector can expose a player to laser hazards. Items that the cauldron can smelt can be processed under the laser instead of magma.

The mod works with Forge fluid pipes, so lava can be moved away from the cauldron. Players should be careful around the cauldron: it stays hot after lava is generated, and a full cauldron that receives more cobblestone overflows. The 1.5.5 update changed the heat system.
