NMEC: separate fragment, fill and mounting system
A field sequence for controlled displays where modern support and ancient material can form a clean silhouette.
This independent observation route is not a condition survey, official map, ticket service or photography permission.
Record the full installation
Photograph object, mount, plinth, backing and light before any detail. Controlled presentation can hide support and make reconstructed orientation seem inevitable. Date the display.
Trace visible boundaries
Follow seams, breaks and fills from whole view to detail. Use alternate angle to test depth and reflection. Do not assign technical categories from color alone.
Separate pose from support
Record where the mount carries or positions the fragment. Describe current orientation and cite the museum or publication for reconstruction. A visitor image cannot reveal internal attachment.
Protect surface uncertainty
Case lighting and dark backing change contrast. Retain the master and avoid diagnosing condition. Seek technical sources for material, treatment and stability.
Create a three-layer diagram
Mark observed edges, source-supported interventions and unresolved areas on a derivative. Publish the unmarked source beside it and version later corrections.
Test responsive release
At phone width, ensure crops retain the boundary or mount named in prose. Attach credits, object record, edits and missing views.
Use clean presentation cautiously
A visually seamless installation can make ancient fragment, fill and support difficult to separate. Seek documented categories and use an oblique view where permitted. Do not treat visual integration as evidence that the object survives complete.
Record background and light
Dark backing and controlled spotlights sharpen some boundaries and erase others. Keep a context frame and original exposure. A dramatic contrast is a display condition, not an independent measure of fracture depth or surface stability.
Compare modules consistently
When reviewing several reconstructions, use the same camera-height category and preserve dimensions from responsible records. Do not rank certainty by how complete or polished a display appears. Each reconstruction needs its own source history.
Publish correction paths
Attach versioned overlays and structured notes rather than flattening annotations into source images. Readers should be able to remove the interpretation, recover the original and see which source supported each intervention category.
Use the responsible museum for access, photography, object availability and professional collection information.
