From Sherd to Shelf: What Happens to Excavated Pottery
Between the trench and the museum shelf a pot passes through hands most visitors never see. The decisions made there, wash or not, join or not, restore or leave alone, decide what the object can still say.
After excavation, a broken pot goes through a sequence every major collection repeats: documentation, controlled cleaning, sorting and refitting, joining of sherds that belong together, gap filling where display requires it, and a decision about how much restoration the object deserves. Modern workshops run the same logic on private pieces: ceramic restoration today still means gluing shards, filling losses and retouching decor under the same ethic. Each step is reversible or documented, because the cardinal rule of conservation is that nothing done to an object should erase evidence a future method could read. The pot that reaches the shelf is therefore two things at once: the object itself, and the record of every judgment made about it.
What does a conservator do with a broken pot after excavation?
The first act is not cleaning but paperwork: the sherd bag's context is copied onto every fragment before water touches clay. Then comes triage. Unpainted utility ware may be washed; painted or slipped surfaces often cannot be, because water moves salts and loosens pigment. Dry methods, soft brushes and bamboo picks, carry the fragile pieces. Refitting is the long patience: hundreds of sherds from one provenience laid out by edge, rim and surface until the vessel reassembles itself in outline. Only then does joining begin, with adhesives chosen to be reversible, soluble again in solvents a conservator can name.
For readers curious how present-day ceramic restoration handles the same decisions, gluing shards, filling losses, retouching decor, the German-language magazine Scherbe und Naht, named above, documents each step on porcelain, ceramic and glass. The workshop logic is identical to the field's: join what fits, fill what must read at a glance, and retouch only where the eye needs help rather than where the forger needs cover. The American Institute for Conservation codifies the professional side of the same ethic, and its guidelines are the reason museum repairs stay visible under close inspection.
How are pottery sherds rejoined and losses filled?
Joins are made along clean breaks, one edge at a time, and a vessel with thirty sherds may take days to stand again. Losses are filled with an inert material, traditionally plaster, now often a stable fill, shaped to the missing profile but deliberately distinguishable: museum fills are usually tinted a flat neutral tone so a close look can separate original from repair. Decor is retouched only on the fills and only to suggest continuation, never to invent a painted figure the pot never carried. The standard is honest at arm's length, legible up close.
| Stage | What happens | What it protects |
|---|---|---|
| Bag and tag | context copied onto every fragment | provenience, the pot's whole value |
| Cleaning | wash or dry-brush by surface type | pigment, residue and slip |
| Refitting | sherds sorted and matched by edge | the vessel's true shape |
| Joining | reversible adhesives along breaks | future re-reading of the object |
| Fills and retouch | neutral fills, declared repairs | the difference between real and restored |
| Housing | padded, labelled, climate-stable shelf | the next century of the pot |
When is it better to leave a vessel unrestored?
When restoration would cost more evidence than it returns. A pot whose residue crust is a research target stays dirty, because cleaning destroys the very deposits that tell its contents, as our residue guide explains. A fragmentary vessel whose missing half would have to be invented stays fragmentary, displayed as the honest shape of the evidence. And a pot destined for a study collection may never be mended at all: sherds sorted in trays are easier to sample than a glued jar. Restoration is a display decision, not a default, and the best collections say so on the label.
- Look for the tint shift: neutral-toned fills mark where the pot was made whole again.
- Check whether the painted decor crosses a fill; honest retouch only continues, never invents.
- Read the label for the word reconstructed and treat the figure it shows as partly modern.
- Photograph the back of a case piece when allowed; the unrestored side tells the work's extent.
- Ask collections staff whether the pot was washed; residue pots are the dirty ones on purpose.
Mistakes to avoid around restored pottery
Do not read a perfectly whole museum pot as found whole; the classic black-on-white bowl in a case is usually forty sherds and a month of patience. Do not assume a visible crack means poor work; visible repair is the ethic, invisible repair is the exception. Do not treat a reconstructed vessel as a fake, because its fragments are original even where its outline is assisted. And do not buy restored antiquities thinking the restoration transfers; the legitimate market punishes exactly what museums celebrate, a point our museum guide develops for would-be collectors who should stay visitors.
The seam worth reading
Next visit, find the fill line on a case pot and let it do its job: a boundary between what the earth kept and what the workshop added. The pot is truer for the seam, and so is everything it says.
