How do I clean an antique glass vase?

Wash the vessel by hand using warm water and mild soap, avoiding harsh scrubbing tools that might scratch the surface. Dry it immediately with a soft cloth to prevent water spots on the clear glass. Take extra care with pieces featuring gilt bronze mounts, enamel work, or delicate etchings, keeping moisture away from metal joins and painted areas.

Were these vases meant for flowers or display?

Many of these vessels served dual purposes as functional flower holders and standalone decorative centrepieces for the home. Large urns and heavy crystal bowls were frequently placed on side tables to catch and reflect light. Smaller examples accommodated modest floral arrangements, while sculptural pieces by major designers were prized primarily as works of art.

What is the difference between lead crystal and standard glass?

Lead crystal contains lead oxide, which gives the material a heavier feel, greater durability for cutting, and a high refractive index that causes light to sparkle. Standard glass is lighter and lacks this high dispersion. Items made from lead crystal often produce a resonant chime when struck gently, whereas ordinary glass yields a duller sound.
