Chromium Burst

Chromium Burst puts you on the oxygen lance of a chromium converter. Carbon burns away second by second and the mouth flame tells the whole story: tall, white and furious while carbon is high, soft, swaying and spark-thin as the endpoint nears. Stop early and brittle high-carbon steel ruins the heat. Blow too long and iron loss plus violent splashing eats your profit. Between those two cliffs sits a narrow target window that shrinks with every new heat.

Read multiple flame cues at once, rock the vessel before the lance freezes solid, and punch STOP BLOW at the exact collapse moment. Bigger converters, thicker fume and tighter windows keep raising the pressure across twelve heats. Win coins, then gear up in the shop: a spectral visor that cuts smoke glare, a fuzzy carbon probe, a stick-resistant lance, forgiving lining, slow burn flux and a spark lens that reads spark density live.

Pure skill timing, no luck. How clean is your endpoint?
