How do I identify genuine 18th century pieces?

Examine the paper quality, ink consistency, and plate marks on printed works. Hand-colouring should show subtle variations characteristic of period application. Check the reverse of panels or frames for signs of age, such as handmade nails, early fixings, or period inscriptions that corroborate the listed date.

Are these works suitable for direct sunlight?

Gouache, watercolours, and hand-coloured engravings are sensitive to ultraviolet light and fade over time. Display them away from direct sun to preserve the pigments. Utilise conservation-grade glass with UV-filtering properties when framing works on paper to protect the delicate media from environmental degradation.

What is the difference between an engraving and an oil painting?

Engravings are printed multiples derived from an incised metal plate, typically featuring fine lines beneath hand-applied watercolour washes. They offer precise botanical detail suited for scientific study. Oil paintings are unique compositions executed on canvas or wood panels with thick, blended pigments, providing richer textures and deeper tonal ranges.

How should I care for textile botanical art?

Textile panels and needlework require stable humidity and temperature conditions to prevent the degradation of wool, silk, and linen fibres. Keep them away from damp environments. Mount textiles behind glass with a spacer to prevent the surface from touching the glazing, ensuring adequate airflow through the enclosed frame.
