Rupture Disc (Flaxbeard's Steam Power)

The Rupture Disc is a block from Flaxbeard's Steam Power. It is used to prevent steam machines from exploding. It is meant to be placed onto a face of the machine. When the machine reaches critical pressure, instead of exploding, it will let the steam out of it. Though, it will continue to let steam out, even when it is no longer at risk of exploding, until it is either crafted with a Zinc Plate, or a Zinc Plate gets used on the block to repair it.
