## About Gilbert Portanier

Gilbert Portanier (1926–2023) was a French ceramicist born in Cannes who died in Golfe-Juan. French authority records consistently identify him as a ceramist, while the available biographical source also describes activity in painting, design, engraving, and sculpture. He is associated with Vallauris and the postwar renewal of French art ceramics there, a context that places his work within both studio craft and fine-art collecting. Ceramics are the best-supported category through which collectors encounter Portanier. Works attributed to him in other media may also surface, although the supplied sources do not establish how frequently those categories appear at auction. Reliable identity matching should use his full name, 1926 birth year, 2023 death year, and stable authority identifiers, particularly Wikidata, VIAF, and IdRef. These identifiers help distinguish documented works and publications from records that merely contain a similar artist name.

## Common works and media

The current evidence most strongly supports ceramic works. Authority records call Portanier a French ceramist, and the biographical source connects him with Vallauris ceramics. The same source also lists painting, design, engraving, and sculpture, so objects in those categories may warrant identity review. The source pack does not establish their auction frequency or document specific recurring subjects, series, editions, or formats.

## Market and appraisal context

The supplied Appraisily dataset associates 302 auction records with this artist entry, but the source pack does not provide a lot-level breakdown. A responsible appraisal should first confirm that the catalogue record refers to the same Gilbert Portanier identified by the authority sources. Ceramic works should be separated from paintings, engravings, sculptures, or design objects before selecting comparables. Relevant records can then be reviewed by object type, sale date, realized price, attribution wording, dimensions, condition, provenance, and edition status when those details are available. The collected evidence does not support a general price prediction, scarcity claim, or market trend, so conclusions should remain specific to the object and the closest documented comparable sales.

## Appraisily data basis

This Appraisily profile combines artist identity research with associated auction records. When record details are available, appraisal research can also consider auction-house context, sale dates, realized prices, and comparable lots; the current source pack does not expose those lot-level details.
