Topic: glass lamps I bought in Italy that I believe are from the +/- 1930s

[jonspencer]

maybe some readers here can tell me what process was used to make this glass finish

from the wiring and original fitting, these lamps are quite old and obviously hand-made if you look closely + rub your hand over the surface

the exterior is similar to frosted and has a light matt texture but the interior is smooth

this is probably the most delicate piece of glass of any sort that I have bought

the other lamp is two-piece and sort of bee-hive shaped with this same matt + clear glass

[jonspencer]

below is the 2 piece lamp

the lamps are from different sources but the first lamp I posted is almost exactly the same weight and texture as the inner cylinder of this lamp

the glass is quite thin + delicate

[Lustrousstone]

It's frosting created either by acid etching or sand blasting

[jonspencer]

thank you for the reply

I forgot to ask is there an Italian name for this glass finishing process?

[jonspencer]

think I found the term

likely satinato or cristallo sabbiato

I was thinking pulegoso but that seems to be different process

[chopin-liszt]

Pulegoso is lots of varying sizes of smallish bubbles in the glass itself.
