How do I clean a crystal bowl?

Wash the glass by hand in lukewarm water using a mild detergent, placing a towel at the bottom of the sink to cushion the heavy material. Avoid sudden temperature changes to prevent thermal shock. Dry the surface immediately with a lint-free cloth to maintain the clarity and brilliance of the lead crystal.

How do I tell an 18th-century piece apart?

Examine the base for a pontil mark, where the glassblower snapped the rod away from the vessel, leaving a rough, ground circle. Eighteenth-century pieces also display hand-blown irregularities and distinct stem formations like air twists. Later Victorian and twentieth-century items often show more uniform machine moulding, sharper machine-cut edges, and heavier lead content.

A tazza is an ornamental shallow bowl or cup raised on a high foot or central stem. Historically used for serving small sweetmeats or fruit, they functioned as display pieces on dining tables. On this page, they appear in moulded crystal with decorative elements like coloured glass canes.

Can I use these bowls daily?

Many of these vessels serve practical purposes as serving dishes, trinket holders, or centrepieces, though older and more delicate pieces require gentle handling. Their sturdy lead construction withstands careful everyday use for food and display. Keep them away from dishwashers, microwaves, and extreme heat to preserve their historical surface finish and metal mounts.
