Topic: Scramble maybe from Murano but how old?

[flying free]

Is the way the base is finished on these Murano weights any indicator of age at all please?
Was there a 'timeframe' when they switched to polished flat bases I suppose is what I mean, rather than the snapped off pontil scar?

Some of the canes.

All I can add to the base finish question is that anything post 1950 (ish) seems to have had the base finished, nearly always by flat polishing, but just occasionally by gently concave polishing: I think I have seen half a dozen of the latter over the years.  I have not seen any information about when that treatment actually started.

From what I can find looking online and in books this is what I have gleaned so far.

An uneven and low dome would be expected in a 19th century weight from Murano, likewise the snapped pontil mark.

Some of the canes in this weight match many in items made for Salviati from around 1870 to 1910, no doubt give or take the odd year.

For a cane with green threads twisted with aventurine on the outside see page 67 Venetian Glass of the 1890s: Salviati at Stanford University: Ewer a Retorti. The same or very similar cane can be seen in my photo 6 - on the right hand side.

For the matching blue and aventurine twist cane, page 83 Venetian Glass  Confections in Glass. The same or very similar cane cane be seen in the centre of photo 6. The previous page also has several goblets made with the white thread and aventurine twist cane which were very widely used in Salviati's wares. For the same or very similar see photo 7.

For the matching pink thread and aventurine twist cane, page 51 Exquisite Glass Ornaments, item 114. Again photo 7 - at the bottom.

I have yet to find any examples of the matching yellow and aventurine cane, or the cane with threads of yellow, pink and green twisted around aventurine (very top photo 6). There is also a similar style cane in the weight but made of white threads wrapped around aventurine, quite like canes in the 'green' glass here: http://www.xupes.com/Antiques-Fine-Art/Product-Details/2722/SALVIATI-CO/Four-Italian-A-Penne-Glasses-19th-C.html

So for the time being my working assumption is this is a late 19th century weight containing the type of canes often used in items made for Salviati.
