Topic: Any ideas on this trailed vase?

[selina]

Sorry for inundating the board but Im housebound atm and it leaves me pondering on my glass

I got this vase at a market stall...I'm unsure of the maker and how modern it may be. It's only a small vase, about a beaker size. The pictures tell the story I guess.

Very much in the style of Peter Goss - but I would expect it to be marked on the base.

I cant find much of his to compare with. I saw the one in the other thread that was similar. The irridescence doesn't really show in the photos well. The trailing is like metal lava almost, around the bowl. No signature that I can find.

I think your iridescent trailing is silver chloride.

Thanks, does the silver chloride, or rather can it, have a purple sheen to it. The whole bowl does, plus the trailing. I just had a real problem picking up the purple with the photos for some reason.

It's hard to tell exactly what's going on from pics, but "sort-of, yes" is my answer!

Silver chloride is a crystalline substance which melts when it comes into contact with the heat of the glass. This allows it to trail around the surface.

As it gets hotter and hotter, the silver and chlorine atoms seperate, giving silver ions and chlorine gas.

Silver reacts with clear glass to give a yellow-ochre (depending on the concentration of ions) colour in the glass, or the silver ions, (in a gaseous form) can give rise to a beautiful ethereal misty blue inside a clear casing, or be a blueish-silvery and yellowish-silvery deposit on the surface.

Your piece does seem to have a blueish ethereal tinge on the surface - but I can't tell if it's been fumed to give a different sort of iridescent surface before the silver chloride was added - which it might have been....

Silver Chloride and glass together do amazing things!

Wow Sue  ! I couldn't even try and repeat that to someone... LOL I'll try and take another shot in different light. See if that helps. Hardly anything I get seems to be signed!!

Close ups... Maybe will give a better idea ?

It's starting to look less and less like silver chloride and more and more like some sort of gilt or iridescent stuff on applied glass trails!

It looks most like silver chloride in pic 21. What pic does the vase resemble most?
Here are two pics of silver chloride effects.

The first is a vase by Jim Megura - the silver chloride effects are all inside the glass, which is basically cobalt blue cased in clear - the rest is silver chloride effects, although I'm sure he's done something Ariel to promote the great big regular long bubbles.

The second is an Isle of Wight Studio Glass gold aurene bell vase - with tons and tons of silver chloride iridesence on the surface.

When the piece is under construction and there is silver chloride doing it's things in the heat, in the glass - if the metal (hot glass) gets detached from the iron, silver gas escapes and depsits itself on the surface.

Neither? The trails are quite raised and embedded? in the glass.. I guess the colour in she second one maybe just a little...
