How do I date an oil painting?

Examinations of the canvas weave, stretcher construction and pigment types offer reliable indicators of age. Stylistic clues within the clothing or landscape elements further narrow the decade of creation. Signatures, stamps on the reverse wood panels and framing techniques also provide chronological markers for verification.

Can I hang these in direct sunlight?

Ultraviolet rays degrade organic pigments, canvas fibres and paper over time, causing colours to fade significantly. Positioning works away from direct southern exposures preserves their structural integrity. Alternative placement on interior walls shielded from harsh light maintains the original vibrancy of the paints and papers.

What is the difference between an oil and a watercolour?

Oil paint utilises a drying oil binder, allowing for thick impasto textures and gradual blending over extended periods. Watercolour uses a water-soluble binder on paper, creating translucent washes. Oils generally require canvas or wood panel supports, whereas watercolours need paper protection under glass.
