Why did artists paint on board instead of canvas?

Rigid panels offered a solid, unyielding surface that required no tension adjustment and resisted punctures or tears. Painters often preferred them for outdoor sketching and smaller detailed compositions. Boards also provided an immediate, smooth tooth that accepted fine brushwork or heavy impasto without the bounce associated with woven textiles.

How do I know if the frame is original?

Original frames generally show matching age indicators, such as shrinkage cracks in the gesso, oxidised gilding, and appropriate backboards or fixings that align with the painting's period. The dimensions of the rebate should fit the panel snugly. Secondary indicators include framer stamps or labels adhered to the reverse wood or paper backing tape, connecting the mount directly to the era of creation.

How should I clean a painted board?

Surface dust should be removed gently with a very soft, dry brush, taking care around areas of thick impasto or flaking pigment. Moisture and domestic cleaning agents must be avoided entirely. Professional conservators should handle any deeper grime or discoloured varnish layers to prevent permanent damage to the underlying oil paint.

Can I hang these works in direct sunlight?

Ultraviolet light degrades organic pigments and accelerates the yellowing of old varnish layers over time. Wall placements should avoid prolonged daily exposure to direct rays. Stable room temperatures and moderate humidity also prevent the wooden panels and frames from warping or splitting along their grain.
