01
Raw block reference
Large volcanic stone blocks establish the starting material visible in the owner-supplied photograph. Source identity and lot relationship still require written records.
MERAPIMaterial process
From volcanic blockto a buyer-defined module.
A transparent process story built only from the material stages visible in the supplied photographs—and explicit about what those photographs cannot prove.
01Observed stages
Material evidence, separated from commercial claims.
The images support a block-to-cut-stone narrative. Capacity, equipment ownership, tolerances, output rate and export history remain unverified unless current records are supplied.
02
Thin natural pieces
The stone is shown in thinner irregular pieces. Thickness range, structural soundness, usable yield and grading are not inferred from this image.
03
Rectangular cutting
Cut tiles are stacked after shaping. A purchase specification must still state nominal geometry, tolerance, edge, surface, sorting and acceptance rule.
04
Surface reference
Dry and wet visual references help discuss tone and texture. A photograph does not replace a buyer-approved sample or performance testing for the intended installation.
02Approval gates
Quality is a set of agreed decisions.
- Reference approval
- Approve stone identity, dry/wet appearance, texture and edge using named media or a physical sample.
- Dimension control
- Write nominal length, width, thickness, units, tolerances, sampling and the accept/hold/reject rule.
- Lot review
- Connect production and packing photographs to a named order or lot before shipment approval.
- Packing review
- Approve internal protection, crate configuration, marks and handling needs against the final format and route.
