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.

How Strong are Glass Countertops?

We are frequently asked about how strong are glass countertops? And for our 1.5″ thick glass countertops e.g. how many supports do we need?

The answer depends upon how much cantilevering or spanning between supports is needed, as well as how much ballast is provided.

We are continually amazed at the strength of our glass counter tops, and how far they can span gaps between, or beyond supports (cantilevering). In the picture below, we are using two supports that are 62″ apart. The glass is 96″ long. This strength has the effect of permitting support with only two brackets…and thus opening up the space between the kitchen and living room. “Floating” is the illusion thus created. The reverse would be having a cluttered support system consisting of eight vertical posts… and that would completely deflate the floating illusion. The countertop is attached to the supports with a large diameter, long continuous bead of crystal clear silicone and is allowed to cure before jostling the countertop. If the countertop is expected to receive heavy jostling, we can always attach two Low Profile Caps to secure it firmly to the brackets.

The custom brackets we suggest are simple, and can modified and fabricated to any design you desire. Frequently, our clients desire that we use these brackets to thrust the glass countertop over the edge of the lower surface…thus enhancing the width of the usable surface area, as well as making the counter more accessible for bar stools…and prevents your guests knees from hitting the lower surface. But be careful, the smaller the cabinet, the higher the risk of the whole cabinet and countertop tipping over. The cabinet itself should be firmly attached to the floor with “L” brackets or anchor bolts to eliminate that risk altogether.

Whatever you kitchen countertop need, we can advise you on counter top support options that will withstand the test of time.
