    "data": {
        "note": "Metal shrinks as it cools from freezing to room temperature, so the pattern must be made oversize: pattern = casting dimension × (1 + shrinkage/100). The patternmaker's 'contraction rule' bakes this in — about 1.0–1.6 % for grey iron, ~2 % for steel and aluminium, ~1.5 % for brass. A 100 mm steel feature needs a 102 mm pattern. This is solid (linear) contraction only; liquid and freezing shrinkage are fed by the risers.",
