"An unstable furnace that can only be reached with a raised conveyor. Processes ore with 75% extra value."
Raised Furnace is a Common-tier furnace that was added in the Ultimate Update and requires a Raised Mini Conveyor or higher to reach. The furnace itself processes ore with 75% extra value (1.75x multiplier) compared to the Basic Furnace's 1x multiplier. For every 80 ores processed in the furnace you will be rewarded 2 research points.
