New mirror can be aged chemically to look antique. My process is vastly superior to what I’ve seen thus far from other sources. You may sometimes order antiqued mirror from various commercial glass houses, but the result typically looks more like an evenly sponged wall than natural aging. It’s also a take-it-or leave it approach in which the customer chooses from a menu of options but is allowed no further input into the process or the final effect. I have a much grater degree of control and am able to create fairly specific effects – various degrees of distress, varying types of patterning, etcetera – all of which will look much more like naturally occurring aging. As always, I invite my customers into my studio for feedback as needed during the process.
