FAQ
Q: What is Temperable Mirror Glass?
A: Temperable Mirror Glass is a vacuum-sputtered coated mirror that can be cut, edged, drilled and physically tempered after mirror coating.
Q: Is Temperable Mirror the same as Toughenable Mirror?
A: Yes. Toughenable Mirror is a supporting market term for the same temperable mirror route.
Q: How is it different from traditional silver mirror?
A: Traditional silver mirror uses silver or aluminum backing and paint, while Temperable Mirror uses a paint-free hard coating designed to survive physical tempering.
Q: Can it be cut before tempering?
A: Yes. Cutting, edge grinding, beveling, drilling, CNC shaping and other shape work should be completed before physical tempering.
Q: Can it be tempered after drilling?
A: Yes, holes and notches can be reviewed before tempering, but hole position, edge distance, size and furnace route must be checked.
Q: What is the standard optical range?
A: The standard range is T0-5/R70-75. The supplied text also gives common values around 1.4% visible transmission and 70.5% visible reflection.
Q: Can other reflection or transmission ratios be customized?
A: Yes. Other transmission and reflection combinations can be customized for one-way observation, mirror-TV facades, stage effects and other projects.
Q: What substrates are available?
A: Low-iron, clear, grey and bronze float glass can be used according to the project appearance and cost target.

Q: Can it be used outdoors?
A: Yes. It is positioned for wet, rainy, coastal, strong-UV, scenic-area and outdoor environments.
Q: Will the coating color change after tempering?
A: The supplied text states ΔE < 0.5 before and after tempering, with no visible color deviation.
Q: Will the coating peel during tempering?
A: The supplied text states no peeling, blistering, discoloration or edge chipping during the approved processing route.
Q: How is export packing handled?
A: Export packing uses heavy-duty fumigation-free seaworthy wooden crates, interleaving paper or anti-mildew powder, desiccant, cushioning and standardized container loading.
