How do I clean an old glass bowl safely?

Wash the glass by hand in warm, soapy water using a soft cloth, avoiding abrasive pads that can scratch the surface. Ensure you line the sink with a towel to prevent accidental impacts against the hard porcelain. Dry the piece immediately with a lint-free cloth to maintain its clarity and prevent water spots from forming on the moulded relief details.

Where should I display an opalescent bowl?

Place the vessel near a natural light source, such as a window ledge or a well-lit cabinet, to activate the milky and iridescent qualities within the glass. Direct sunlight highlights the contrasting tones of the moulded design. Ensure the surface is stable and protected from heavy traffic to prevent accidental knocks against the substantial weight of the crystal.

What is the difference between crystal and clear glass?

Crystal contains added lead oxide, which increases the weight, refractive index, and resonance of the material compared to standard clear glass. This composition allows for deeper, sharper cuts and moulding. In practical terms, crystal pieces feel heavier in the hand and produce a clear ring when gently tapped, whereas ordinary glass lacks this acoustic property.
