Meaning and boundaries
Monolithic does not mean annealed. A single lite can be annealed, heat-strengthened, fully tempered, tinted, or coated.
Why it matters in glass restoration
A technician must distinguish a single lite from laminated or insulating constructions before choosing a procedure or interpreting surfaces.
