Undisolved Silica?
« on: October 30, 2005, 06:18:33 PM »
This 50p vase of mine looks old to me but probably not to anybody else.

The base has plenty of ware to it.

Did you see the dark green swirl in the second picture? I might be wrong but I think this is what they call undisolved silica. Or am I barking up the wrong tree? I read about this someware and it indicate's age (you know what books are like though).

Also, there are about 20 very small green lumps dotted around the vase which are the same colour as the swirls.

I previously had a victorian green cranberry glass (that's what my local auctioneer called it) with the same streaks of dark green. This vase had small white lumps?

Any information or comments welcome. Thank's.  :)

Hi Tigerchips   :D

What a great colour this vase it...peacock blue!  Kind of retro, eh?

I think this could be Spanish (recycled?) glass.  I was previously calling it Mexican (recycled) glass, but I think Ray corrected me.  I've got a piece very similar in content, which I bought thinking it was a Per Lutken piece (it was a BAD photo, ok??!) and now I use it for flowers.   :wink:

Thank's Max, Perhaps the vase is so cheaply made it is easily scratched (which would explain the ware on the base).

I've seen Murano vases shaped like this but they were much better quality.

Is this what they call Soda glass? It is light and looks very brittle, I think this is because there is no (or very little) lead or lime content in the glass. Or not.

I only paid 50p so I might make a penny profit.  :lol:

WF do have soda glass, but theirs is without random odd shaped bubbles (as far as I know - more than willing to be corrected!) and this one has a rough pontil, I've never seen any WF so badly finished.

I think I'll take a breather for a bit...don't think I'm thinking straight.

Agreed Max, I wasn't suggesting TC's was W/f - TC's piece hasn't the look of W/f at all, and you're spot on about the quality and the pontil, I was just adding to Frank's comment about Monart being soda glass. :) (BTW my one and only piece of W/f is an amethyst soda vase, which is the only reason I know anything at all about this Max!  :lol: I'm almost clueless about W/f.)

No one seems to have answered Tigerchips' question about what IS soda glass.  Strictly, there is no such thing.  The term is used (too often imho) as an abbreviation of "soda-lime", which is itself an abbreviation of the correct "soda-lime-silica", which describes accurately the main constituents.  The vast majority of everyday glass comes under this description.  Windows, bottles and all everyday household glass (apart from "Pyrex") of whatever colour are included.  Potash (usually) and lead replace the soda and lime at the upmarket end of things.

Tigerchips, there IS a glass which contains no lime or lead, just soda and silica.  Sadly, it dissolves in water.  Our grandmothers used it for preserving eggs under the name "waterglass".

Thank's Adam.  :)

A Dissolving Wine Glass? That would be a good party trick.

I think the wine would still end up on the floor though. :lol:

The only piece of Whitefriars soda range that I have is a carafe. I don't think I should've bought it without the beaker though.  

Carafes without beakers, decanter's without stoppers and vases without frogs. One of my little habits I'm afraid.
