How should I protect vintage watercolours from light damage?

Watercolour pigments and paper substrates remain sensitive to ultraviolet radiation from direct sunlight, which causes fading and discoloration over time. Displaying them away from bright windows preserves the original colour intensity. Utilising conservation grade framing materials and UV-filtering glass provides an additional layer of protection against environmental deterioration.

Are these paintings executed on paper or card?

Most of these works utilise traditional rag paper as a flexible base for water-soluble pigments and ink applications. Some specific Asian examples employ stretched silk instead of paper surfaces. Heavier weight papers and boards offered artists adequate durability to support wet washes without excessive warping or structural failure.

How do I identify the period of the framing?

Original frames often display period construction methods, such as corner mitres joined with wooden slip blocks and aged backing boards secured with old nails. Gilt wood and ebonised finishes show authentic wear patterns consistent with age. Replacing historical frames risks removing part of the object's provenance, making original housing particularly desirable for collectors.
