0.6.1 — Pressure Chambers

Build a sealed room, set a Chamber Valve in one of its walls, and it becomes a pressure vessel. No multiblock pattern to memorise — the valve finds the room by flooding it.

The walls are the difficulty curve. A chamber holds only as much as its weakest block: glass 4 bar, stone 12, iron and obsidian 45, voidsteel 150. Fences and slabs aren't airtight and the room won't close around them.

• The valve has no ceiling. It pumps until the walls start leaking — that equilibrium is the real limit of your chamber.
• Chamber Regulator holds the room at a pressure you dial in, bleeding the excess back into your pipes.
• Recipes run on items thrown on the floor: sponge dried under vacuum, moss in ammonia, leather in ozone, blue ice in cryomist, crying obsidian in voidbreath at 90 bar.
• Dry ice and pressure glass: two new blocks, one condensed from CO₂, one a window that doesn't cost you the whole pressure range.
• Vacuum boils water into steam, and 25 bar turns it back. A vacuum chamber with a water supply is a steam plant.
• Break a pressurised pipe or chamber wall and it goes off. Drain your lines before you cut them.
