Marble lamps w/ sticker SG who made them?

Hello, Ive had quite a few of these lamps, but never had a manufacture sticker still on them. I've been looking around, but haven't found it yet. Anyone recognize company?

 

I think you could safely make something up without fear of contradiction, if they were not someone amazingly famous, they were just some blokes in an Italian shed.

Round about 1960 or 70 probably. Carrara marble comes in that veined type as well as dead white.

 

SG might be the export company.
They might have only dealt with lamps.

Is it marble for sure and not alabaster?

I believe they are marble. I always think of Alabaster as being somewhat opaque. I had a pair of really nice alabaster lamps once, and you just knew as soon as your looked at them that they were alabaster. I wouldn't mind some more input on that though.

 

Alabaster is the translucent one,marble is opaque. Alabaster inhales dirt that won't wipe off, marble wipes clean (unless you leave it outdoors for 400 years) Alabaster is soft enough to scratch with tough fingernail, marble takes steel to scratch it.

 

I think (therefore, I don't really know) marble is colder, because it is denser.
Alabaster melts with water, so more porous and often found with a shellac coating.

Personally, I can't tell from a picture, I was just asking.
I've just always thought those lamps were alabaster. I never considered they might be marble.

 

Hi,
Easy scienific way to tell if things are marble or alabaster. marble is calcium carbonate. Alabaster is calcium sulfate. make a tiny scratch on the bottom. Using a loupe to see put a drop of white vinegar on the scratch if tiny bubbles or fizz it is marble. No fizz it is alabaster. Besure to rinse off the scratch. Some people use lemon juice but that stains, the same with red vinegar.

Thanks, gonna try that. I let you's know what happens!

 

They look like marble to me too, from here. In fact, they look like the marble slabs they used by the bathroom doors in my house.(LOL)
