Tempered Mirrors

Beautiful safety mirrors done right.

Wait, you can do that?

Yes. Tempered mirrors are not just possible, they’re beautiful and essential for spaces where impact with the mirrors is likely and where laminated mirrors are not required.

To get a tempered mirror, first glass is fabricated (if desired), then tempered, and finally silvered. Choosing a vendor that can do all of this in-house minimizes potential for quality issues and delivery delays that could arise when using multiple vendors.

We’ve been perfecting mirror manufacturing for over 60 years. AND we just installed a brand new, state-of-the-art tempering oven. All on-site, in-house. Kiss your frustrations with tempered mirrors goodbye. We got you. 👊

Glass Break Comparison

When broken, tempered mirror crumbles into small granular chunks instead of splintering into jagged shards like annealed (non-tempered) mirrors. These chunks are less likely to cause injury, which is why tempered mirrors are considered a type of safety mirror.

Tempered glass is used in manufacturing mirrors where safety is the paramount concern. Due to anomalies that are inherent in the tempering process, tempered mirror can not be held to the same quality standards of annealed mirror.

Surface blemishes that should be anticipated include scratches and rubs.
Because the glass must be tempered prior to silvering, these blemishes can be encountered on both the face and silvered surfaces.

Silver overspray on the edges of tempered, polished edge mirrors is something that is unavoidable. This is the result of the process to produce this product. The glass must be edged prior to tempering. Silvering is the last step in the production process. Overspray on the edges is typical for this product.

Also inherent in tempered glass is an increased level of distortion. This distortion is due to the energy trapped in the glass by the tempering process. This creates a certain amount of bow or warp. The visual effect is further amplified by the application of the silver reflective coating in the mirroring process.

Alternative options include annealed mirror with safety backing or annealed mirror laminated to tempered clear or low-iron glass.
