What is a chrystoleum portrait?

A chrystoleum is a photograph placed under curved glass, rendered translucent with oils or watercolours before the paper backing is removed. The technique was popular during the Victorian era for adding depth to standard prints. Artisans applied pigments by hand to the reverse side, creating a vibrant finish that mimics a genuine painting when sealed inside its frame.

How do reverse glass prints work?

Reverse glass painting involves applying pigment directly onto the back of a glass pane in reverse order, starting with fine details and finishing with backgrounds. When turned over, the final composition appears correctly oriented through the glass. This method preserves the colours from environmental wear and gives the surface a distinct glossy sheen characteristic of Georgian and nineteenth-century domestic art.

How should I clean glass portrait frames?

Cleaning antique frames requires care to avoid damaging delicate gilding, gesso, or aged wood surrounds. Use a dry, soft brush to remove dust from crevices without applying moisture to vulnerable surfaces. For the glass itself, apply a small amount of neutral cleaner to a cloth rather than spraying directly, ensuring liquid does not seep behind the pane.
