A full polishing range.
From cutting and one-step correction to final finishing.
Clear and identify the glass-coating station between products or batches so materials, tools and production records cannot be mixed accidentally.

A changeover can leave the previous product in a dispenser, an unlabelled working container or an applicator on the bench. A short line-clearance routine prevents that material from entering the next glass-coating run.
List product containers, working vessels, applicators, labels, travellers and rejected panes from the previous run. Resolve partial containers according to the approved storage and identification procedure. Do not pour unidentified leftovers back into stock.
| Check | Evidence |
|---|---|
| Product and batch | Matches the job instruction |
| Tools and cleaning state | Suitable for the next material |
| Labels and records | Correct job and revision |
| First pane | Identified and inspected before routine output |
Removing old labels and materials is not the same as validating a chemical cleaning procedure. Where products are incompatible or residues matter, use the supplier-approved equipment cleaning or dedicated tooling arrangement.
If the operator leaves halfway through clearance, mark the station as not released. The next operator should know what remains to be checked without reconstructing the process from memory.
A second-person check may be useful at critical changeovers, but it should verify specific items rather than add an unexplained signature. Small facilities can use a documented self-check with clear physical separation where appropriate.
Record the previous and next material, unresolved items, clearance completion and first-article result. A practical checklist should take less effort than investigating a run whose product identity cannot be established.
