Split view: sand lab clipboard showing seven parameters at 25°C versus molten metal pour at 1,300°C with thermal degradation, gas generation, and silica expansion physics

How many parameters does your lab test? Seven, probably. Now: how many do you change simultaneously when you adjust a recipe? One. Maybe two. But in your sand system, all seven change simultaneously every time you change one. This is what your lab data is hiding from you.
