About ALBAVIT

A recipe-controlled oxide system, not a mineral source.

ALBAVIT is engineered from the ground up around a tight chemistry window — every oxide sized to a specific structural function, every batch certified to the same composition specification.

Unlike feldspar, recycled cullet, or other glass frits with broad tolerance bands, ALBAVIT is recipe-controlled. The product delivers identical Fe₂O₃, alkali, and silica values across every shipment, every fraction in the mesh ladder, and every production batch.

It is in commercial production today, available across the complete mesh range used in premium slab manufacturing, and certified by three independent accredited laboratories on three continents.

Industry Context

Premium slab manufacturing is transitioning away from crystalline silica.

A regulatory arc that began in Sydney is now arriving in California, with material substitution moving from optional to mandatory across premium product lines.

2024

Australia

Engineered quartz banned category-wide.

Australia became the first country to outlaw the highest-silica engineered stone segment. A US$2B+ product gap opened overnight, accelerating supplier realignment toward amorphous, low-silica filler systems.

2025

United States

OSHA enforcement intensifies.

Respirable crystalline silica enforcement is tightening. California — the largest US engineered-stone market — is studying category restrictions. LA County held public hearings on a ban. Other states are watching.

2026+

Global

Liability extends across the value chain.

Silicosis case law is evolving toward "knew or should have known" standards. Distributors, brand owners, and material suppliers face mounting exposure. Insurance carriers have already begun adjusting premiums.

Performance

Three properties define ALBAVIT against industry-typical glass frits.

Iron, alkali, and process precision distinguish the product from competing fillers and from mineral-sourced alternatives like double-floated sodic feldspar.

< 0.05%

Ultra-Low Iron

Color neutrality engineered in

Fe₂O₃ below the standard limit of reporting eliminates the black-spec defect at source. Double-floated sodic feldspar cannot match this — residual iron in flotation product is lattice-bound and structurally embedded in the mineral.

< 2.00 %

Controlled Alkali

Network modifiers minimized

Total alkali sits an order of magnitude below the typical 5–15% range of other glass frits. Lower alkali means reduced thermal expansion, less alkali leaching in service, and tighter color stability through firing.

2.5MT/hr

Process Precision

Industrial throughput at higher vitrification

Production at 1620°C, 120°C higher than competing glass frits with more than twice the throughput. The combination delivers cleaner melt behavior and tighter optical consistency in the finished material.

Comparison

How ALBAVIT compares to current filler categories.

Performance against double-floated sodic feldspar, recycled glass cullet, and other glass frits across the metrics that matter to slab manufacturers and brand owners.

Certifications

Independently verified across three accredited laboratories.

Three labs on three continents have certified ALBAVIT for zero crystalline silica content using three separate analytical methodologies. The chemistry is protected by a granted United States patent.

Applications

Two production-ready application paths.

ALBAVIT replaces crystalline-silica fillers in two distinct application categories. Both substitutions can begin within a single production quarter, with co-development support from our technical team.

Application 01 · Drop-in

Replace feldspar in white and light-tone slab bases.

ALBAVIT replaces double-floated sodic feldspar as the primary filler in white, off-white, and light-tone slab recipes. The substitution is drop-in compatible with existing polyester resin systems and current press-line equipment — no retooling, no chemistry redesign, no production downtime.

Eliminates lattice-bound iron and the black-spec defect at source
Removes residual quartz still present in flotation product
Identical whiteness batch-to-batch through recipe control
Thermal expansion engineered to reduce resin-matrix stress

Application 02 · Co-developed

Replace cristobalite in translucent and onyx surfaces.

ALBAVIT replaces β-cristobalite as the optical filler in translucent and onyx-aesthetic slab products. We formulate the amorphous oxide system for refractive index matching, preserving the translucent depth of the finished surface while removing the high-temperature crystalline silica polymorph that sits at the top of the next regulatory wave.

Translucent depth preserved through amorphous optical structure
Zero crystalline silica eliminates β-cristobalite exposure
Recipe expansion enables new color and depth options
Co-developed with customer R&D over 60–90 days
Existing manufacturing process retained without modification
