Quartzite knowledge

Resolve identity before promoting quartzite.

Five of 8 live routes are quarantined because colour or appearance wording does not identify a stable material. ASTM C616 separates quartzite, quartzitic sandstone and sandstone; petrography, source and lot evidence must resolve the offered programme.

Discovery is retained; unsupported claims are blocked.

Quarantine preserves route lineage while stable identity, geological class, source, media and current supply are established.

3 routes

Differentiated trade programmes

Resolve named programme, geological quartzite identity, source, movement, mica/mineral content, fissures and lot continuity.

Retain trade discovery but require source-linked petrography and current slab/lot evidence before enhanced claims.

4 routes

Generic colour quarantine

Replace colour-only identities with a stable quarry/deposit or governed trade programme while retaining legacy search lineage.

Do not publish origin, performance or differentiated-product claims until identity, source, media and lot are approved.

Appearance descriptor quarantine

Separate a style word such as Rustic from a material identity, finish, source and geological class.

Define the actual stone programme and model Rustic as appearance/finish metadata if evidence supports it.

Rustic ⚠

Evidence matrix

Prove class, source, lot and fabrication controls.

Method-specific evidence stays linked to the specimen and offered lot.

Stable identity

stable-identity

Quarry/deposit or governed trade programme, accepted aliases and blocked generic substitutes.

Quartz-based class

quartz-based-class

Source-linked petrography/free-silica framework confirming quartzite rather than sandstone or quartzitic sandstone where required.

Source & lot

origin-and-lot

Country, state/region, quarry/program and block/bundle/lot chain at the precision claimed.

Fabric & orientation

fabric-orientation

Foliation/banding, cutting direction, test orientation, slab sequence and installation orientation.

Visual range

visual-range

Current slabs/tiles, movement, mica/minerals, fissures, repairs, translucency, finish and approval reference.

Processing disclosure

processing

Resin, mesh, fill, repairs, dye/enhancer, sealer and reinforcement.

Dimensions

dimensions

Finished size, thickness/tolerance, calibration, flatness, squareness, edge and cutting direction.

Absorption & density

absorption-density

Lot-linked ASTM C97 or agreed method with specimen, condition, lab, report and date.

Strength evidence

strength

ASTM C170, C99 and C880 kept distinct with wet/dry state and relevant orientation.

Abrasion & slip

abrasion-slip

Exact-finish, traffic- and wet/dry-specific evidence for floors, paving or wet areas.

Weathering exposure

weathering

Mineral stability, oxidation, freeze–thaw/deicing, wetting/drying and staining assessed for destination.

Fabrication safety

fabrication-safety

Supplier/fabricator crystalline-silica controls, wet methods, extraction, PPE, waste and applicable occupational rules.

Finish control

Finish must be approved on the exact lot.

Mineralogy, fabric, resin and fissures affect response.

Polished

Approve mineral reflectivity, resin, fissures, scratch response, wet slip and exterior stability.

Honed

Confirm shade, mica/mineral response, scratches, sealing and exact wet/dry performance.

Leather / Brushed

Approve mineral relief, cleanability, food-contact maintenance, edges and lot range.

Natural cleft

Control foliation/cleavage integrity, relief, thickness, loose flakes, lippage and wet slip.

Flamed / Textured

Confirm safe uniform response, thickness loss, surface integrity, edges, slip and weathering.

Application control

Hardness alone does not prove suitability.

Assembly, exposure and project evidence govern use.

Counters & worktops

Conditional

Exact slab, fissures/repairs, thickness/support, cut-outs, edge, resin/sealer, stain/thermal expectations and care.

Interior floors & walls

Conditional

Traffic, finish, calibration, lippage, abrasion/slip, substrate, joints and visual mix.

Exterior paving

Engineering review

Confirmed lithology, thickness, loads, drainage, finish, slip, abrasion, climate and mineral weathering.

Wet areas

Engineering review

Exact-finish wet slip, drainage, chemicals, absorption, fixing and maintenance.

Façades

Engineering review

Panel design, fabric orientation, flexure/anchors, wind/seismic loads, joints, drainage and weathering.

RFQ checklist

Turn a generic name into an auditable programme.

Require the same identity, source, evidence, inspection and safety fields from every supplier.

1.Stable trade/quarry identity and blocked substitutes
2.Quartzite versus sandstone/quartzitic sandstone evidence
3.Quarry/program, block/bundle/lot and origin chain
4.Application, destination, exposure and standard
5.Slab/tile size, thickness, tolerance, edge and direction
6.Finish plus current slab/range approval
7.Resin, mesh, fill, repair and treatment disclosure
8.Method-specific lot tests and acceptance criteria
9.Inspection, sequence/layout and replacement policy
10.Fabrication safety, packing, Incoterm and handling

Blocked shortcuts

Colour-only identity as a product programme.

Quartzite class inferred from catalogue family.

Shared name merged across families.

Hardness used as a complete suitability claim.

Fabrication without crystalline-silica controls.

Specify quartzite by stable identity, class and lot.
