Topic: How was this vase made?

[kwqd]

This pink vase is about 12" high x 8" wide at the widest point. The bottom is ground flat and maybe slightly polished. Guessing it is probably Chinese. Wondering if anyone knows how it was made? At first, I thought the design was etched, but when I magnified it, it looked like some sort of mesh was laid over it and maybe sealed with another layer of glass or some other material. Then I looked at the bottom and it appears that something more complicated took place. the mesh seems to have been applied earlier in the process and stretched? Not sure. Does anyone know how this was done? The vase not signed or marked, so guessing the maker will remain a mystery. Thanks!

The technique's called 'filigrana' (this specific lattice design, if I recall correctly, 'filigrana a retortoli') - essentially, it's (usually) made by arranging decorative glass canes on a table, picking them up on a bubble of molten glass, working them until they're flat to the surface, then blowing the vase.

20th Century Murano would be a good bet.

Thanks for the explanation and information Pinkspoons. Very interesting.

There are some nice videos on YouTube, really worth watching.

Thanks Anne! I will take a look at YouTube. I am very interested to see how this was done.

Here are a couple of good videos:

I found another vase that is nearly identical to my vase, on ebay. After looking at my original post, I see that I forgot to mention the color, which is the same faint lavender color mentioned by the seller. Unfortunately, the seller is away, but I will try to contact him/her. Here is their description of what they know about the vase:

VINTAGE 12" TALL MURANO, ITALY VENETIAN LATTICINO FILIGRANA HAND BLOWN VASE

"I'm Selling a Unique & Beautiful 12" Tall, Hand Blown Vase with Tapering Spiral Lattice Ribbons running from the pontil on the bottom up to the hand crimped top edge.  The Vase is a very faint lavender overall color, measures 12" tall, is about 5 1/2" across the top and 7" at it's widest diameter - the glass is about 1/4" thick.

Description: I've enjoyed the hand blown Art Glass from the Island of Murano, Italy for forty years, and I've never seen a vase with this wonderful, intricate lattice ribbons pattern on it.  The faint lavender color is also unusual!  The vase was purchased at a Wealthy Estate Sale in Northwestern Wisconsin many years ago (from a large collection of Murano Glass (much of which was marked with the usual paper sticker)."

Update: Contacted the seller (Ed) and got a "out of office message" which says he is unavailable until 2/14/2019.

I missed part of the seller's description which involves the pontil treatment:

"“The Vase is very lightly used. As with all art glass, there is no such thing as perfect! You will find a small manufacturing mark, bubble or line in the glass. There aren't any cracks or chips. As usual, the pontil on the bottom is ground smooth and even."

Seller responded that he has no further information and is pretty firm about identifying it as Murano but no proof.
