Glass / Re: Harrach? Frosted Blue Vase.
« Last post by NevB on September 21, 2022, 01:52:26 PM »
I found this vase which is very similar but much more ornate, the foot design looks identical.

There are also several other pieces on this site with a similar rim design and assuming the attribution is correct I think mine is by Harrach and around the same date.
British & Irish Glass / Machine etched comport stamped with pattern number 16
« Last post by neilh on September 21, 2022, 12:08:53 PM »
I picked up this machine etched comport recently, Height 6in, Width 7in
Density 2.89g/cc which is decent lead content and rules out the northeast of England for what I think is a late Victorian piece.

I suspect it is not from the northwest either as the glass is very thin.

The chief oddity about this one is that there is a pattern number 16 stamped on the top plate belly button.
As you can see it's in a little circle of its own. This is not proud to the surface, you can't feel either the number or the ring around it.
Not sure how that would have been added.
I'm guessing with these features it might be closer to 1900 than 1880.

Has anyone ever seen a machine etched set with a number, or an idea how it was applied?

Are any manufacturers known to number their pieces like this?

Nice. Like the Romanesque piece. I’m fairly confident that the colour, described earlier as ‘Nordic Green’ is pretty close. Rather hoping mine is a piece by either Poli or Barovier!
Glass / Frosted Uranium Vase.

This relates to the blue vase I recently posted. The rim is not the same shape but is a similar style and the base is roughly smoothed. The gilding on the bowl has worn off leaving a pale purple base layer. Height is 27cm.

Thanks m, the pink vase looks to be the same, there is also a large vase in the middle cabinet in the same blue glass. I'll keep looking for a maker unless someone can give a positive ID. I think you are right about the date as the ones I saw on Ebay had the earlier date of 1850-70. I found this in a local antique centre and the dealer obviously didn't put any value on it as it was priced at £1.  ;D. I've got another uranium vase with a similar rim which I'll post.

Yes, I’m sure the goblet in the Harrach book has been mechanically ground, especially given what is said in Farbenglas. It’s a shame though that they don’t seem to say anything in the Harrach book to indicate when they might have started to also use acid matting, they just say ‘matte treated’. It would be useful to know when acid matting became available as an option.

For those without the Farbenglas book, page 127 showing the mechanically ground goblet can be seen here:

Not sure how much use there two photos are but the items have a similar colour and iridescence, I am somewhat hazy on who made them but probably had them down as Salviati when I sold them. Have since seen another attribution for the bowl but unfortunately don't recall what that was.

Farbenglas II shows a matt ground (agatised? -) superb goblet  on page 127 from Neuwelt.  It dates to 1837.  I think the description she gives on page 274 indicates this was mechanical ground (agatised? - ).  It's incredibly smooth and silky in the photograph and looks acid etched but it isn't.  She doesn't mention acid etching at all as far as I can see.  Her description of the surface being ground and the people who did the work is interesting.

Thanks, the effect looks similar to the decanter that started this thread but hard to see from the photo. They don’t seem to differentiate between types of matte treatment though, for example on page 188 plate 224 is an 1885 vase that is also ‘matte treated’, but perhaps by then it was matte treated by acid rather than abrasion.

Just noticed that MacConnell The Decanter page 281 says “The [acid etch] technique was bolstered from 1860 by the invention in France of white acid, a hydrofluoric acid/alkali solution that left a matt-white effect similar to engraving. Pellatt and others exhibited white acid decoration in London in 1862 and Paris in 1867”.

So according to McConnell white acid frosting was invented (first?) in France in 1860 so presumably it was just mechanical abrasion before then. White acid from Pellat isn’t mentioned by Hajdamach or Northwood II that seem to say in the U.K. white acid was invented by John Northwood I in around 1867. Hajdamach also says white acid “was known on the Continent well before the 1867 date of Northwood’s use”. That sounds earlier than McConnell’s 1860.
