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.

We love clients that bring us their creative ideas and engage us to bring their custom Custom Glass Countertop for a Kitchen Island high bar to life.

Freida was one such client. She had a very defined idea about an organic shape and the way the textural flow should flow inside the piece. We digitized her sketch and waterjetted her outline exactly as she wanted…in cardboard first. This cutout was placed in our kiln sand bed where we scribed the outline. The texture for this piece was done in her presence, and after much give and take we were satisfied with the texture for this unusual piece.

The 1.5” thick glass top was fused and annealed in our oven for 5 days. We then took the template and placed it atop the oversized fused glass, and scribed exactly where the waterjet would cut. We then hand-polished the curvaceous edge to perfect optical clarity with a soft roundover all around. No CNC machine can equal the quality of hand-polishing…especially with textured glass. The resulting edge allows the client to peer inside the glass…it is magnified, and an exceptionally interesting view to behold.

The plan called for a three-legged support system, partially atop her kitchen island to a height of 42”.

We had our stainless steel fabricator create (2) 3.5” diameter steel tubes that were 40” tall, and (1) that is 4” tall. Upon these the glass would be secured. Three holes were waterjetted in the glass high bar for the Low-Profile Stainless Caps. The long posts were ruggedly secured to the floor, and the short leg through the island countertop.

Carefully shooting the floor with our laser-level made short work of a complex 3-D siting.

The glass was set in place. The result was magnificent. Soon after it was set, the sunshine beamed through her window and illuminated the glass in an exceptionally beautiful and unexpected way. Quite a stirring moment indeed.

We have attached a few pictures of this dramatic piece.
