Remaining thickness

The measured or defensibly estimated glass thickness that remains at the thinnest part of a treated area after material removal.

Meaning and boundaries

Nominal original thickness minus an assumed abrasive depth is not a reliable value unless both inputs and their uncertainties are established.

Why it matters in glass restoration

Remaining thickness affects geometry, distortion, strength questions, and whether further material removal should stop.
