Protocol
Every conclusion travels with its evidence.
EGP™ holds no inventory and represents no seller. Services are undertaken only where an honest answer is possible, and the boundaries of that answer are always written down.
01
Enquiry
Describe the material, the question to be answered, and any prior reports. We confirm whether the question can be answered responsibly.
02
Examination
Observation is conducted in a controlled setting, beginning with non-destructive methods and escalating only where necessary and agreed.
03
Documentation
Findings, images, instrument readings, and the limits of the conclusion are recorded together — never a verdict without its evidence.

Report
A written statement is issued in plain scientific language, suitable for citation, insurance, appraisal, or academic reference.
