The patterning process begins with the design stenciled and masked onto the surface of the glass or acrylic. Our artisans then utilize a media or acid application to create a three-dimensional effect that will transform any glass or acrylic component.

Our Historic Glass Restoration Capabilities Include:


Grand Light artisans specialize in the cleaning of glass and acrylic diffusers by offering both hand cleaning and ultrasonic cleaning technology.
Ultrasonic cleaning is done using Brulin Aquavantage 815 GD industrial ultrasonic cleaning tanks with patented high performance generators followed with a delicate hand cleaning process. Additionally, our artisans utilize a proprietary cleaning solution before each component is rinsed and hand polished.


Grand Light artisans have decades of experience repairing broken glass and lead joints. Our restoration methods include lead came and UV Light Curing Adhesive repair. For UV repair, our proprietary resin must be injected into a crack or chip before being cured by our UV curing lamps.
As paneled or stained glass ages, the lead joints can become brittle or oxidizes, leading to broken or damaged joints and/or panels. Repairing this damage requires repurposing and cutting the existing material while soldering the existing lead.


Correct glass fitment is essential to providing a secure fit that prevents foreign material from entering the interior of fixture. Additionally, temperature exposure on exterior fixtures can vary greatly, and is taken in great consideration to ensure heating/cooling cycle does not create stresses in the glass or acrylic.
Fixtures that are UL wet-listed are designed to endure wet outdoor conditions and inhibit water on live parts or other electrical components for a safe and long lasting installation. Grand Light standard quality control involves testing and verifying the proper and secure fitment of all existing and/or new diffuser installations on all custom or restored lighting fixtures.


Some projects require the modification, fabrication, or addition of custom components, lenses, or frames to accommodate project goals.
In these scenarios Grand Light specialists will carefully modify existing or custom glass components without compromising the historical integrity of these glass components.
