Glazed Lava Stone
PyroArch™
Begin a CommissionColor that lives
in the surface.
Forever.
Downing Designs fabricates custom glazed lava stone countertops, bar tops, and tabletops for high-end residential kitchens, luxury bars, and commercial hospitality environments. Each surface is individually specified — color matched to any Pantone reference, paint chip, or fabric swatch — then kiln-fired at over 1,400°F until the enamel fuses permanently to the stone.
The result is not a coated surface. It is a glass surface, bonded at the molecular level to a volcanic substrate that has already survived 2,000°F. The color on installation day is the color in twenty years.
Unlimited Custom Color
Any Pantone reference. Any paint chip. Any client swatch. Metallic oxide colorants are mixed, fired, and permanent. No other countertop material category can make that statement.
Zero Maintenance. Ever.
The surface is fired glass enamel — inorganic, non-porous, chemically inert. No sealant schedule. No renewal cycle. No sensitivity to acids, pool chemicals, or UV exposure.
Domestically Fired
PyroArch™ is fired in Tampa. No European freight delays, no August factory closures, no customs complications. Text us in August — we answer.
Volcanic Substrate
Lava stone has survived 2,000°F. Our kiln fires at 1,400°F. The result is dimensional stability and thermal resistance that no engineered stone can replicate.
Architect-Specified
Full specification documentation available. Standard 30mm thickness, custom sizing, and Pantone-referenced color sampling for project submittals and FF&E schedules.
Personal Installation
Every installation is performed by Jeff Downing. White-glove delivery, precision fit, and a surface that arrives exactly as specified — every time.

One craftsman.
Every stage.
No substitutes.
Jeff Downing has personally designed, fabricated, delivered, and installed every piece since 2000. There is no factory, no production team, no outsourced fabrication. Kiln dimensions reach 130 inches — large enough to produce single pieces that European suppliers cannot air-freight. That is the difference between a seam and no seam.
About the StudioBefore You Call
What is a kiln-formed glass bar top?
A kiln-formed glass bar top is a single piece of glass heated and fused in a kiln to create texture, depth, and seamless spans up to 130 inches — as opposed to cast resin, laminated panels, or seamed sections. Every piece is fabricated by hand in Tampa, FL, with no outsourced production.
How large a single piece can Downing Designs pour?
Single continuous glass pieces up to 130 inches are produced in-house on Denver Glass Machinery kilns. Larger installations use engineered multi-panel layouts with Singularity™ seaming to preserve visual continuity across the full span.
Does Downing Designs install outside Florida?
Yes. Downing Designs has fabricated and personally delivered custom glass bar tops, countertops, and lava stone surfaces nationwide, handling design, fabrication, delivery, and installation directly — no subcontracted install crews.
How long has Downing Designs been fabricating glass?
Founder Jeff Downing has been the sole craftsman behind Downing Designs since 2000, personally handling every piece from initial design through final installation for over 25 years.
What's the difference between a glass bar top and glazed lava stone?
Glass bar tops are kiln-formed from a single piece of glass. Glazed lava stone (PyroArch™) is a fired-enamel surface applied to a volcanic stone substrate, offering a stone-textured alternative with different heat and outdoor performance characteristics.
