Wood Finishing & Decorative Techniques (Medieval–Renaissance)

Overview

Finishing in the Middle Ages and Renaissance drew on materials available to painters and builders: oils, natural resins/varnishes, glues, pigments, waxes, and occasionally veneers, inlay/intarsia, and gilding. Evidence survives in workshop treatises, household/building accounts, surviving objects, and later technical histories.

Topics at a Glance

• Paint – protein- or oil-bound pigments on wood (often over gesso grounds for furniture or interior woodwork).
• Glue – hide and fish glues for sizing, grounds, and joinery.
• Oil – linseed, walnut; used as binders or wiping oils; sometimes combined with resins.
• Varnish – spirit or oil varnishes using amber, copal, sandarac, mastic, etc.
• Veneer – thin decorative facings; more common in later periods and specific regions.
• Inlay & Intarsia – wood and occasionally bone/ivory/metal inlays; hallmark of Italian workshops.
• Carving – low to high relief; often polychromed or glazed with translucent finishes.

Conservation & Materials Science

• Dorge, Valerie & F. Carey Howlett (eds.) – Painted Wood: History & Conservation
  Collected papers from conservators; strong on layer structures, binders, aging, and examination methods. Technical but invaluable background.
• Doerner, Max – The Materials of the Artist and Their Use in Painting
  Broad survey of artist materials and historical practice; a touchstones text for media properties and workability.
• Eastlake, Charles – Methods and Materials of Painting of the Great Schools and Masters
  Historical commentary on painting media with citations (varying depth). Useful for varnish and oil narratives.

Regional & Object Studies

• Chinnery, Victor – Oak Furniture: The British Tradition
  Documents paint on furniture (Tudor–Stuart) and discusses period color and finish expectations.
• Binski, Paul – Medieval Craftsmen: Painters
  Readable survey of craft practice, tools, and products; useful visual context for workshops and finishing scenarios.

Modern Technical Guides (for understanding processes; not endorsements)

• Flexner, Bob – Understanding Wood Finishing
  Clear explanation of finish chemistry and film formation—handy for translating historic names to modern behavior.
• Thompson, Daniel V. – The Materials and Techniques of Medieval Painting; The Practice of Tempera Painting
  Practical and historical explanations of gesso, tempera, and glazes relevant to painted furniture and interiors.

Varnish, Lacquer & Trade Histories

• Huth, Hans – Lacquer of the West
  Useful background on European lacquer/varnish traditions, guild structures (e.g., Venetian varnishers), and object types.
• Stalker & Parker – A Treatise of Japanning and Varnishing (1688)
  Post-medieval but influential in English practice; reference point for late 17th-century varnish and decorative recipes.
