Casting the Future in Stone
A new way to build. A new era of permanence.
What is Heirloom Stone?
Aggregate
This is the “body” of the stone. Any clean mineral material can serve as aggregate: crushed granite, basalt, quartz sand, desert sand, river sand, marble dust, even recycled Heirloom stone. For best results, aggregates with mixed grain sizes (from fine up to a few millimeters) create optimal density and a natural granite appearance. Whatever aggregate you choose becomes the visual and structural backbone of the finished block.
Waterglass
Potassium or lower-concentration sodium waterglass acts as the clear binder. When catalyzed, it transforms into silica gel — a glassy, glass-hard matrix that locks the aggregate grains together. This is the equivalent of natural quartz binding real granite, but formed at room temperature without heat, pressure, or machinery. Potassium waterglass usually performs best, forming a stronger, more water-resistant gel.
Catalyst
A tiny amount of slaked lime (around 2%) triggers the entire transformation. It destabilizes the waterglass just enough for silica gel to form instantly and evenly. The lime doesn’t become the binder — it just nudges the waterglass into solidifying. Wood ash can perform the same role if it contains enough calcium, making the process accessible even in remote or off-grid conditions.
What’s Possible with Heirloom Granite
Heirloom Granite unlocks a new era of building — one where anything you can imagine can be cast in permanent, non-toxic stone. Using simple molds and local earth, structures that once required massive budgets, specialized labor, or industrial equipment can now be created safely, affordably, and beautifully.
Below are just a few of the forms, structures, and creations that become possible with this material.
Homes & Architecture
Heirloom Granite allows anyone to build structures that are stronger than concrete, more beautiful than brick, and more durable than natural stone — for a fraction of the cost. Homes, cottages, cabins, and entire neighborhoods can be cast by hand or produced at scale.
What’s possible:
• Single-family homes
• Multi-unit dwellings
• Remodels & additions
• Garden walls & courtyards
• Fireproof, weatherproof shelters
Interior Features
Anything you can sculpt or mold can become a permanent part of your living space.
Examples:
• Countertops
• Tiles
• Sinks & basins
• Shelving
• Decorative panels & relief carvings
Outdoor & Landscape
Heirloom Granite thrives outdoors: it doesn’t rot, burn, rust, warp, or decay.
Examples:
• Walkways & stepping stones
• Fountains, pools, ponds
• Retaining walls
• Garden beds & planters
• Outdoor furniture
Art & Sculpture
Early-stage Heirloom Granite can be carved with hand tools; fully cured, it behaves like a fine-grained natural stone.
Examples:
• Statues
• Monuments
• Ornaments
• Architectural flourishes
• Custom engraved pieces
Structural & Industrial
With proper engineering, this material can replace conventional masonry or concrete in many applications.
Examples:
• Load-bearing blocks
• Pillars & beams
• Vaults and domes
• Acoustic-proof or thermal-mass walls
Modular Systems
With interlocking block molds, communities can build fast, strong, reusable structures with no specialized skill.
Examples:
• Modular construction blocks
• Modular tiny homes
• Emergency shelters
• Pop-up workspaces
• Workshops & garages
Urban Renewal
Materials can be recycled indefinitely. Entire districts could be rebuilt with permanent structures, zero waste, and minimal cost.
Examples:
• Housing projects
• Public buildings
• Transit stations
• Cultural landmarks
Extreme Environments
Heirloom Granite is resistant to heat, cold, radiation, pressure changes, and erosion.
Examples:
• Desert architecture
• Off-grid survival shelters
• Arctic facilities
• Planetary habitat components (Mars, Moon, etc.)
If You Can Mold It, You Can Make It
Every object shown here — from countertops to cathedrals — shares the same simple recipe: local aggregate, a mineral binder, and a catalyst. Heirloom Granite transforms the way we build by returning to the most ancient, durable, human technology: stone.
The Future is Ancient.

Heirloom didn’t start with a business plan. It started with a question that’s followed me most of my life:
Why accept anything at face value when you can go looking for the truth yourself?
My name is Jeff Haney, and I grew up in Wendover on the Utah–Nevada line. We didn’t have much, but curiosity was free, and that shaped me more than anything. I learned early that if something didn’t add up, you dig deeper. That instinct played into everything — the music I made, the ideas I chased, the strange corners of physics and philosophy I tried to understand — always looking for the simple truths hiding under complicated assumptions.
When I came across Marcell Foti’s work, something resonated immediately. It didn’t feel like a gimmick. It felt like a rediscovery — a reminder that powerful ideas can come from unlikely places and still be incredibly practical. When he released his work openly to the world, that generosity lit a spark. If a material can be clean, strong, durable, non-toxic, affordable, and simple enough for anyone to make… then it shouldn’t stay a curiosity. It should become a tool for everyone.
My dad, CJ Balch, joined me on this journey. He’s spent his whole life in Nevada’s music world, approaching everything with heart, grit, and curiosity — traits that fit this mission perfectly. Together, we created Heirloom not to “own” anything revolutionary, but to help people use something that already belongs to all of us.
Heirloom Granite is simple at its core — local earth, waterglass, a tiny bit of catalyst — and the result is a material that performs like natural stone while costing a fraction of traditional construction. It doesn’t burn. It doesn’t rot. It doesn’t warp. It cures into something meant to last generations, not decades. And unlike concrete or steel or lumber, it can be recycled endlessly, repaired easily, and cast into almost any shape people need or imagine.
Our goal is to take this idea to useful at scale.
That means producing high-quality waterglass.
Designing molds anyone can use.
Creating modular building systems.
Teaching families and builders how to adopt it.
And eventually helping cities rethink what safe, affordable, lasting architecture can be.
Nevada is where we’ll prove the concept.
Detroit is where we’ll build the engines of production.
And anywhere people need stability, dignity, and opportunity — that’s where Heirloom belongs.
The material is strong, but the idea behind it is stronger: People deserve structures that don’t fail them. Families deserve homes that endure. Communities deserve materials that don’t poison them or drain their budgets. Societies deserve strong, beautiful architecture that future generation can inherit with building practices that don’t leave a trail of waste behind.
Timeless. Timeproof. Heirloom.
