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.

Lava Stone Countertops A Colorful Countertop Option

Glazed lava stone is a countertop category built for color. Cabinets, islands, and backsplashes in saturated, permanent hues are driving modern kitchen design right now, and glazed lava stone is the material making that possible — a fired vitreous enamel glaze fused onto a volcanic stone or nanoglass base at over 1,500°F. The result is stain-proof, hot-pan-proof, and UV-inert in a way granite, marble, and quartz simply are not.

Traditionally this category has meant quarried volcanic stone from France (Auvergne) or Italy (Mount Etna), shipped, glazed, and freighted to the U.S. — with the long lead times and cost structure that implies. Downing Designs developed PyroArch™, a fired-enamel-on-nanoglass alternative, built and fired domestically in our Ybor City studio, to bring the same category — full-color, fireproof, permanent — to American kitchens without the overseas supply chain.

Glazed Enamel colors:

See the attached pictures to get an idea of the vivid colors available in enamel glazed countertops. There are many standard colors to choose from and an infinite ability to color match your samples. No other countertop material we know of possesses the ability to have such a dazzling array of colors.

Matte or Glossy are the finishes available. Metallic finishes are also available.

FAQ Frequently Asked Questions

How much do glazed enamel lava stone / PyroArch™ countertops cost?

Quarried European lava stone typically runs from roughly $400/sq ft on up. PyroArch, fired domestically, is priced without the overseas freight and import lead time built into that number. Full color intensity isn’t required to make a statement — pairing a PyroArch accent (an island, a bar face) against White Glass Countertops for the perimeter is a common way clients get the color-pop effect at a lower blended cost, since white glass runs less than half the cost of full-color glazed surfaces.

Look at the picture below. Its a very smart use of white countertops with a brilliant light blue island countertop makes this kitchen exceptional.

Q: How do we Template for Glazed Enamel Countertops?

Templating is done the same as any other countertop material. Since this material is NOT adjustable in the field, templating is critical to make sure we get the overhangs, sink cutouts, faucet holes, angles, etc. correct. A good seam plan is also important. This is where a professional well-versed in kitchen design and implementation must be used. Be prepared to answer many questions concerning your decisions for the final layout. Once templated, you must freeze any added work that changes the layout.

How durable is glazed lava stone / PyroArch™?

The production method — fusing powdered glass enamel onto a stone or nanoglass base under kiln heat — is the same family of technology behind vitreous enamel signage that has survived 25–40+ years in outdoor, high-traffic environments like the London Underground since the late 1800s. It’s weatherproof, resistant to acids and alkalis, and graffiti-proof. Properly designed and installed, a glazed enamel countertop is a multi-decade surface, not a remodel-cycle surface.

Key Factors Driving Durability:

Production Process: The Lava Stone countertops are made by fusing layers of powdered glass onto the lava stone base material.
Environmental Resistance: They are completely weatherproof, resistant to acid, alkalis.
Maintenance: Vitreous enamel is graffiti-proof and easy to clean.
Performance vs. Alternatives: They last up to four times longer than standard powder-coated panels.

Why fire it domestically instead of importing quarried lava stone?

Import lead times on quarried French or Italian lava stone commonly run weeks with limited responsiveness once a quote is requested. PyroArch is fired in our own studio, which means faster turnaround, direct communication with the person doing the firing, and no ocean freight in the cost structure.

Using colorful Lava Stone in your kitchen or bath will set your design apart from others. Having an experienced design eye assist you is invaluable…especially one that offers a wide variety of materials to complement your Lava Stone selection. Properly designed kitchens can expect many decades of use from their lava stone countertops.
