Compare the producer’s sample photographs and confirm the current range and finish.

Aqua Grantique is a Wisconsin hornblende gneiss from Krukowski Stone’s Aqua Quarry. Its dark blue to gray range can contain olive, white quartz and rust-colored veining. Commercial granite is a marketing classification; the producer identifies the quarry rock as gneiss.

Documented capabilities

Blocks

Yes

Quarry capability: the producer explicitly describes Aqua Quarry block extraction. Block dimensions and current mine record match remain unresolved.

Slabs

Yes

Producer product: cladding slabs/panels, not a quarry-gate service claim.

Source

Cut to size

Yes

Producer fabrication service.

Available finishes

Shot-blast; Brushed; Honed; Polished; Corduroy

Material-specific cladding finishes. The custom-cut page highlights brushed, honed and shot-blast.

available thicknesses

3 cm; 2 1/4 in; 3 1/2 in

Producer cladding-panel thicknesses; other products have separate dimensions.

Source

current recommended panel size

15 in × 30 in

Current producer guidance because natural seams restrict large-format yield; not a universal maximum for every product.

Source

thermal finish

Current material-specific text states that Aqua Grantique is no longer thermalled.

Source 1 · Source 2

rock faced finish

Current producer text says Aqua cannot be rock-faced because it fractures erratically. Existing photographs may illustrate earlier products.

Restoration and matching

Archival source notes: Previously classified under commercial granite in Quarried’s NSI-derived record; the producer now identifies the quarry rock as hornblende gneiss. This preserves the former classification without changing the canonical Aqua Grantique name.

Confirm before specifying

Ask the supplier about current availability, material range, fabrication and test data for your application. A listing or MSHA status does not establish supply readiness.

The producer links an Aqua Grantique ASTM and chemical-composition report. The original report has not been reviewed here, and no test values have been imported. Current finish and panel-size restrictions follow the material-specific producer pages.
