Viewing windows, doors, and panels for laboratory and scientific equipment. Tight tolerance, low-iron clarity, and printed graduations or masks fired into the glass.
Tempered lites for instrument doors and enclosures, cut to tight tolerance.
Thicker lites where the panel sees pressure differential or impact.
Ceramic frit graduations, borders and blackout masks fired in permanently.
Hardware holes, standoffs and notches cut before tempering.

Need a spec not listed? We quote off your drawing. Colors we usually keep on hand.
DXF, DWG, PDF, a dimensioned sketch, or a photo of the part. We check holes and edge distances against the tempering limits before we price it, so the number is for a part we can actually make.

Yes. Ceramic frit, fired during tempering. Cleaners and repeated wiping do not take it off the way they take off pad printing or film.
± 1/32" on cut size is standard. If your seal needs tighter, tell us before quoting and we'll say honestly whether we can hold it.
It depends on the pressure and how you need the glass to fail. Send the application data. We would rather turn a part down than ship one that fails in the field.
A short note on the part is enough for a first number. Drawings and photos welcome.
