Where should I hang these works?

Position paintings away from direct sunlight and sudden temperature fluctuations caused by radiators or fireplaces. Stable indoor humidity prevents the canvas and wooden stretcher frames from warping or cracking. Mount the piece securely using appropriate hardware suited to the weight of the frame and the wall construction. Avoid damp spaces such as unventilated bathrooms where moisture can degrade the organic materials.

How do I identify the period?

Examine the construction of the stretcher frame, the weave of the canvas, and the style of the clothing or sitter's hair. Old canvas often exhibits characteristic oxidation, craquelure, and stable shrinkage patterns unique to aged oil paint. Compare the handling of pigment and framing styles against documented examples from specific centuries. Expert consultation can assist in dating ambiguous provincial works where signatures are absent.

Craquelure is the fine network of microscopic cracks that forms across the surface of aged oil paint as the medium hardens over centuries. This natural process occurs as the paint film loses elasticity and responds to environmental shifts. The presence of stable craquelure often serves as an indicator of genuine age in historic paintings. It distinguishes authentic older works from modern reproductions that lack natural pigment degradation.
