Run the melt shop. Ship real alloys.
Catch the right atoms, keep slag out of the ladle, and pour coils of Cu-ETP, CuZn37, CuSn6 and CuNi18Zn20 — with real technical data on every coil you ship. Keyboard or touch, one screen, no signup.
The metallurgy is the game mechanic
Cu×3 pours Cu-ETP. Cu×2+Zn pours CuZn37 brass. Cu×2+Sn pours CuSn6 phosphor bronze. Cu+Ni+Zn pours CuNi18Zn20 nickel silver.
A wrong element or a chunk of slag adds an impurity. Two impurities and the ladle is scrapped — you only get three per shift.
When the melt is dirty, a green P atom appears now and then. Catch it and the melt is deoxidised — the same job P does in a real bronze shop.
Every three coils, quality control asks one real technical question from the coil data you just shipped. Right answer, +250.
