How do I spot a real art deco flask?

Examine the vessel for characteristic geometric lines, stylised floral motifs, and period materials such as opalescent glass or guilloche enamel. Signatures or maker stamps etched into the glass base or stamped on the silver mounts provide further confirmation of origin.

Are these flasks meant for daily use?

While originally designed to hold and dispense perfume on a dressing table, many antique flasks are now appreciated primarily as display objects. Older stoppers and delicate atomizers may not seal perfectly, so contemporary collectors often keep them empty to preserve the interior.

How do I clean an old perfume bottle?

Dust gently with a soft, dry cloth and avoid submerging pieces with paper labels or glued metal mounts in water. If the interior requires cleaning, rinse carefully with warm water without using harsh chemical solvents that might damage coloured glass or enamel.

What is the difference between frosted and opalescent glass?

Frosted glass has a uniformly matte, acid-etched surface that diffuses light evenly across the vessel. Opalescent glass shifts in colour depending on the light source, displaying milky blue tones alongside warm amber highlights due to its chemical composition.
