Title: Brown/green lobed bowl with acid-etched (Corroso?) finish
Post by: rocco on October 01, 2011, 12:35:39 PM
Dear Murano experts,

bought this beautiful lobed bowl/ashtray today, diameter appr. 16 cm, brown cased in green (maybe clear glass as well, difficult to see).
The green may have Uranium content, but I cannot check before monday...

Underside with several circular indentations, base heavily worn.
Outside and inside with irregular acid-etched finish -- referred to as "Corroso" I guess.

Any ideas of age/maker? (This time I am very positive that this is a Murano piece ;D. If not -- my apologies to the mods)
I have seen some Seguso pieces with similar finish and colours on the net, but I guess this technique was used by several makers...

Thanks!
Michael

????

I have never seen a finish like that on Murano glass in my Internet travels -- so I await to hear replies on it too.   It is Neat!!  :thup:

Thanks a lot for your answer, Rose!!

Like you, I knew this technique only from pictures so far (for instance a great Flavio Poli "Corroso" vase depicted in Lesley Jackson's book), so I had to get this nice piece :)

Here are several links to Murano pieces I found on the web, with similar or almost identical finish:

It would be great if some of the Murano specialists could shed a light on this one!
Thanks,
Michael

Ok, one more thing to add: tested it under UV, and it glows green like crazy! (My very first piece of Uranium glass :))

So, any chance that at least my Murano attribution (and the Corroso technique) could be confirmed? Maker or date is a different matter I guess...

Thanks!
Michael

here is another  ONE with texture  (http://www.antiquehelper.com/item/307449)   and yours also Glows, now I am  :mrgreen: :mrgreen:

Good for you  :thup: and your first piece of Uranium Glass too  :chky:

My first thoughts when I saw the bowl was perhaps it was Seguso or Archimede Seguso. The bowl reminded me of some of their work. Wish i could say something more definite about it.

Thanks a lot Rose and Anita!

After doing quite a bit of internet research during the last days, it seems that "Corroso" pieces are much less common than items in other Murano techniques (and most are attributed to the major companies).
From what I have read, the use of the acids was strictly limited from the 1960s on due to anti-pollution regulation (don't know if this is true); I guess this would indicate my bowl was probably made before that date?

Interesting piece.  It's different from most (all?) corroso pieces that I've seen in that it's not a simple shape. As you point out, it has lobes, not unusual in Murano, but I've not seen in corroso.  I have three piece of corroso, as you point out in another thread. One is Seguso Vetri d'Arte (it has a label and it's typical of what SVd'A exported to North America). The other two I'm much less sure about about. The little bowl I was pretty sure was Murano when I bought it. However, when I later bought the vase in the same colours, I became less sure, as the finish on the vase isn't what I'd expect of Murano, especially around the mouth. I did some digging and it seems that companies outside Italy had made corroso since Murano stopped making it. So corroso can be non-Murano and post 1950's.

Having said that your piece looks very much like Murano to me with it's shape and colours. If Murano it's 1950's or earlier.  I couldn't suggest a maker, but I wouldn't be too surprised if it were SVd'A. I also wonder if Archimede Seguso did corroso.

David, thanks a lot for looking into this!
The bowl is by far my most interesting Murano item, so I am curious to learn more about it.

I have read a thread on the fossilfly forums where a Corroso piece was finally identified as French 1930s (I think you contributed there as well :)), so I am aware that there are other possibilities than Murano -- but this one just screams "Murano!" to me :D
Your green/blue Corroso vase is great, where ever it may have been made.

I did quite a lot of internet research on Corroso and Murano, and you are right that most pieces have a rather restraint shape.
After looking at hundreds of bowls and ashtrays I couldn't find anything similar to mine (not even shape-wise -- closest are some deeply lobed Barbini bowls). But none has the deep bumps to the underside.
And that I have seen Corroso pieces by all of the big companies doesn't help in attribution either...

Thanks again,
Michael

I'm not sure if this will help at all or lead anywhere, but I'm pretty sure I've seen a similar shaped bowl by Galliano Ferro, with uranium casing and large dimples, but without the Corroso finish.

Wayne, as soon as I saw your name, I also remembered a similar shape by GF. The company was formed before corroso was banned (or limited), so it is quite possible. I can't think of any corroso I've seen from GF, but it could be out there.

Thanks a lot, Wayne and Anita!
I searched a little for Galliano Ferro pieces, but didn't come across the one you refer to; the only one (attributed) with dimples I could find is in Christine's gallery: http://lustrousstone.co.uk/cpg/displayimage.php?pid=497 (http://lustrousstone.co.uk/cpg/displayimage.php?pid=497)
But the style of this one looks different I think...

Worst part is this piece reminds me of several companies/makers...Barbini, SVdA or Archimede Seguso. Definitely a high quality piece and I reckon not very common as well. The uranium casing throws me though. If it had a strong sommerso effect I could probably help more...

I have a "similar" piece like yours...still unindentified...

Thanks very much, Kane! I like the crackle effect in your bowl.

I'm not sure if one could refer to my bowl as Sommerso? -- Outer Uranium green layer, inner brown layer (the dark and light parts are due to strongly varying thickness of glass I guess). Why are you thrown by the Uranium casing?

At least the hotworked, slighly unusual shape does't look "generic" to me, which leaves some hope that it could be identified one day :)

I mean't i am better with sommerso pieces. Uranium is uncommon here in good glass, i see it mostly in Europe in the US so i don't have many pieces. Also, I own a few pieces but have never seen them glow!!!  :o They are all packed away.

And this piece is generic...it looks really good...a great find... :hiclp:
