What does kiln-carved mean on a glass bar top?

Kiln-carving is a process in which glass is fired in a kiln over a textured bed — in this case, a hand-worked sand surface — so the heat softens the glass and allows it to take on the precise contours of the texture beneath it. The result is a surface that is permanently part of the glass, not applied to it. The texture lives on the underside, meaning the top surface stays smooth and cleanable while the visual depth lives below, amplified by the LED light source behind it.

How is a glass bar top supported without drilling through the glass?

Three cantilevered steel brackets, anchored into the bar structure below, carry the full load of the glass surface. The glass rests on the bracket faces and is bonded with ultra-clear silicone — no hardware passes through the glass at any point. This eliminates stress concentration points, aesthetic intrusion, and future maintenance issues caused by through-drilling.

How does the LED lighting system work inside a kiln-carved glass bar top?

The Ambiance Machine™ RGB LED system mounts along the interior edge of the bar structure and fires light upward through the glass. The carved texture catches and scatters that light, creating a surface that appears to glow from within. The system operates across 8 million color combinations at 0–100% intensity, with programmable scenes and optional photocell trigger that activates the bar automatically at dusk.

What are the maintenance requirements for a kiln-carved glass bar top?

The surface requires no special treatment. The top surface is smooth polished glass — cleaning is the same as any glass surface, a damp cloth or standard glass cleaner. No sealing, no waxing, no periodic treatment required. Low-iron glass is non-porous, does not stain, and does not react with alcohol, citrus, or cleaning products.

How was the wave texture pattern developed for the Mantoloking glass bar top?

The texture was designed interactively — client and craftsman working from the bar's geometry and the room's flow to arrive at a pattern that felt native to the space. Once the bar base drawings were confirmed, multiple textural iterations were developed. The client selected the wave pattern, which was then scaled and anchor-pointed so the hand-worked sand bed in the kiln matched it as faithfully as the process allows.

Glass Counter atop Robern Vanity

Recently, we had the pleasure of installing a custom glass countertop to accessorize a 48″ Robern V14 vanity at Ferguson in Tampa, Florida. The result was a pleasing, colorful and modern combination. We love the way the Robern vanity is intelligently built to accommodate multiple power sources for your hair dryer, and in this case, our LED light strip attached to the back edge of the glass countertop. It is also solidly constructed in its framework, and we were impressed. The pictures below were captured under differing ambient conditions. You can see that this vanity will be very easy to see in the middle of the night, and beautiful by day as well.

Our LED is multi-color and can be adjusted to any of 1000 colors, an brightness settings.

The drawers are internally illuminated to allow you to visualize the drawer contents with out turning on the bath room light.
