Finnish Bent Birch Furniture: Aalto, Korhonen and Identification

Finnish bent-birch furniture developed through experiments by Alvar and Aino Aalto with Otto Korhonen's production expertise. Laminated bends, moulded plywood and standard components allowed resilient modern forms, later produced in many editions.

Context before attribution

Begin with chronology, geography and intended setting. National and stylistic labels conceal regional differences, changing borders and later revivals. Printed designs, exhibitions, trade and migration spread forms beyond the workshop or country now most associated with them.

Material and construction evidence

Identify model, designer and authorised manufacturer.
Compare laminations, moulds, dimensions, hardware and labels.
Look for delamination, over-sanding and altered finishes.
Separate early manufacture from later genuine editions and copies.

Inspect the full object: structure, secondary woods, back, underside, drawers, hardware and surface. Record how veneers, paint, inlay, stone or metal relate to joints. Colour and ornament alone are weak evidence; finish, fading and restoration can radically change appearance.

Marks, makers and dating

A label, stamp, inscription or model number must be recorded exactly, including its position. Confirm its documented period of use and whether the marked component belongs to the whole. Design attribution, manufacture and later authorised production are separate questions.

Build a date range from design, materials, manufacturing method, hardware, surface and provenance. Contradictions often reveal replacement, remounting, a married base or later edition.

Reproductions and alterations

Look for redundant holes, cut panels, different oxidation, interrupted paint, modern boards, transferred labels and standardised later hardware. Revival makers can copy visible style convincingly; hidden construction usually gives a more balanced picture. Old restoration can itself acquire patina.

Condition and conservation

Map lifting veneers, paint loss, failing laminations, loose stone, corrosion and structural movement. Preserve original and significant historic surfaces. Never strip, sand, polish or dismantle an object to make identification easier. Regulated materials and important maker attributions require specialist advice before sale or treatment.

Examination checklist

Photograph every face and component.
Record dimensions, materials, marks and provenance.
Map repairs and replacement parts.
Compare with documented museum objects and primary sources.
Separate certainty, probability and unresolved questions.
Keep all findings with the object's permanent record.
