Start with the clay entry. Open the original sheet when the details matter.
Each published entry pairs the studio’s clay label with a dated test record. The report number, testing unit, EDXRF method, instrument, testing basis and recorded result stay beside the original report sheet instead of being reduced to a marketing claim.
Use the report number or clay label to locate the record, then open the source sheet when you need the exact test document for a sourcing or review conversation.
