It does, but I think I know kind of what you mean.

I'm sure these were complicated to make.  Added to which , some of them were cased in coloured glass and then silvered, then cut.  Imagine being the glass cutter on the final stage of the process - you wouldn't want to make a mistake and damage that glass.

I have one that has a gold interior.  I've still not worked out exactly what method was used to do that process.


 without a doubt many knew of this technique but mastering it was another story. as I recall there were some wine carafes that used a similar technique where there was a recessed reservoir where there was ice placed and then the wine was in the main container that allowed you to pour the wine and ice just cooled the wine and the wine was poured from a spout opposite the ice reservoir.
the more I think of this in making goblets, etc. the outer layer of glass may have had to be blown into lightly as the center section was formed with the wood jacks, otherwise the outer bubble might have collapsed as the inner portion was tooled inward. This probably required some selective heating of different portion of the bubble to allow parts of it to be formed as the outer bubble retained it's form.
I know this sounds cryptic and hard to understand without some visuals or drawings.
Glass / Re: Could this be Argos?

Argos 1 of my images would appear to be the underside of the butter dish. Not sure whether the ring motief was on the lid as well! (When will I find one!!!!??)

Here it is (if you didnt find it)

Also a pink cheese bell.

Is your list available somewhere?

Started to collect this pattern a year ago in Norway.
Thank you Tom!

So, perhaps Cyril was 'mislead' by the 'hardening of lungs' story.
It does perhaps mean then that these glasses were made like this, taking into account the Whitefriars experiment with Cyril there and also Malcolm's experiment recounted in British Glass.

ok, but ... just because a Whitefriars blower knew how to do it, this doesn't mean the technique was unique to Whitefriars and since many were made in a variety of Bohemian factories, in Germany and in Belgium, France and the USA (source Das Bohmische Glas Band III pp 130)  there must have been many places that knew about this technique.

This is a true description of what was accomplished.
One also sucks the air from one's blowpipe when using a "pineapple" mold that has undercuts and thus collapsing the bubble to allow it to be removed from the mold. Normally one does not suck air from the pipe but in special instances it is done. It is not easy and requires a good amount of practice to achieve this. By the way, the air is normally not hot by the time it reaches the glassblower's mouth or enters his or her body. Timing and knowing when the glass is at the exact temperature to achieve these techniques and how hard and long  to suck was a special talent and remains that way even today.
 I have taught many students and as hard as they may have tried to make mistakes and suck some hot air, they were never able to achieve getting any hot air to their mouth. The greatest problem was that the blowpipe would get extremely hot and would then have to be quenched with a pipe cooler or wet papers that would reduce the temperature of the pipe itself.
Glass Paperweights / Re: Peter Holmes Gnome Paperweight
« Last post by millarart on Yesterday at 02:49:22 PM »
 Noddy and Big Ears weight arrived today  its engraved on base Scottish Borders Art Glass Peter Holmes 2006 also has his signature cane on base and fully labelled, alright so maybe not the best detailed  weight ive seen Noddys face isn't great lol but unusual for Peters work and it had not been an easy item to make and I bet it took a lot of time and effort and I just love it cant believe I got it so cheap.   it makes a nice addition to a Scottish weights collection, Noddy and Big Ears are set on a mottled purple ground ,  the weight measures 3 1/4 inches across by 2 inches high , quite a heavy weight for its size weighing just over 1.1lbs /500gms,
3)  This is another photograph of the previous page in the Great Exhibition Catalogue.

It shows a company called R. W. Swinburne - pp125

it mentions silvered glass (though I have no idea if it was silvered using a similar process to the Varnish process)

Just a thought because Varnish mentions they showed 'Reflectors' in silvered glass so perhaps a company that could make industrial type equipment as well made their glass?
And if you read through Swinburne's production they look like a possible candidate for making Varnish silvered glass maybe?

Interestingly there was a link between Swinburne and Chance Glass (see link on GMB here),18417.msg106531.html#msg106531

Worth reading.  He seems to have gone out of circulation for a bit at some points? maybe at the point where the Varnish glass stopped being made?  Just assumptions and surmises by the way!  Don't want to see these surmises quoted as facts anywhere  ;D
1)  This is a photograph I took of part of the Exhibitor listings in the Great Exhibition catalogue

Interesting to note that as well as mentioning 'silvered glass' under 27. E.Varnish
it also mentions 'or-molu and silvered glass chandelier' under 32. Green, J.G.

Now,  who knows if the 'silvered' word description in both 27. and 32. means the same technique? 
But if it does, then that was two exhibitors showing 'silvered glass'.

2) under 27. E.Varnish is also says they were showing 'silvered glass reflectors, applicable for artificial illumination' (Chance glass sprang to mind for some reason on reading that). 

quote 'I have no problem with the idea of an assistant helping the final "easing in" of a partially collapsed upper section of the vessel by gently and slowly withdrawing air'

But exactly how would they gently and slowly withdraw air?

Charles is specific on his description - it's just weird.

I have spent a lot of my life in the manufacturing business.

I have also delved into patents.

Lets step back and look, as I think Keith or Paul wrote.

Two companies would HAVE to work in extremely close quarters. We are looking at the merger, albeit tenuous, of two companies. This was for THE GREAT EXHIBITION, this was not Wembley Market on a Sunday morning.

As pointed out by lustrous, just setting up a glass making venture was expensive, let alone one that combines two different mediums.
Not only that, but I don't think Thomson and Varnish just knocked on the door a week before the Exhibition and said "hey, we got some mercury we want you to play with.

Powells were obviously quite established at the time and would have recorded this major re-shuffle, surely?

I am still trying to find out more about Mellish and Lund, as I think they may be another avenue which may lead to an answer.

Whichever way you look at it, there is a company or was a company that had some significant changes to its working practice, a new influx of funds, possible relocation due to hazardous chemicals, and I don't think Powells fits the bill somehow?
