Excalibur

"The legendary blade Excalibur stores the value of ores that are sacrificed to it and stacks it onto all new ores for a short time."

Overview
Excalibur is an Exotic tier furnace that was exclusive to May 2016 and was introduced in the Outdoors Update. Unlike other furnaces in Miner's Haven, this does not multiply orevalue by a specific number.

Excalibur has a unique effect where it stacks orevalue from ore previously processed by the furnace. Its effect is complicated and it actually isn't useful without the unique ability of adding one ore's value to another. However, this is widely considered to be the best furnace in the game, as it can make ores of low value become profitable if used correctly.
