Official basis (Research): Specialist petrographic practice. Use a documented validated mineral-identification procedure; no universal official stain protocol is assigned.
Procurement note: No official universal procedure was authenticated. Confirm pretreatment chemistry before ordering; HF-based variants require specialised compatible containment and consumables.
