Topic: Ferro & Lazzarini ?

[rosieposie]

Absolutely no offence taken Sue,    unless you are 'into' Crystal Therapy you couldn't be expected to know why we who are, dismiss goldstone as having 'healing' properties.
Goldstone is produced in much the same way as Sach has so clearly described... the 'Lump' of glass and copper mix is placed in the furnace and the outer parts that become overheated are written of as waste, it is the inner core that  is not overheated which is used to make the 'gemstones' that are sold as goldstone.
It is very pretty and quite costly due to the wasteage, but it has none of the Piezo-Electric properties of Quartz, and as the colour is artificially produced, neither will it work in Chakra Balancing.
I feel much as m does, that this paperweight has lumps of something unattractive within, and one thought was... could it be that we are all correct, and that these lumps are pieces of the overheated waste goldstone...??  Just a though?

So:-
That's me, Flying-free and you, Rosieposie, all think, no matter what the accuracy or not of the writing on it, or what it says, that the weight itself is a bit of total tat which would strongly suggest that whatever is written on it is designed to decieve.

[rosieposie]

I suppose that unless you get to see the piece 'in the flesh' as it were, then that would be a difficult statement to make.  It could be that it was the best that artist could produce... the only thing I feel certain about is that it most likely is not Ferro & Lazzarini.

I was being overly harsh using a word like "tat" - I certainly couldn't make it! 

I've seen things of this type and quality, mostly in boxes which are labelled Royal Crest or Leonardo Collection or in heart foundation shops.
I do think it is a good few years since I've seen ones with goldstone lumps in them.
I do have significant memory problems, but I know I have seen weights like these before, en masse.

These weights have been discussed before but I can not find the topic now. Here is one with a label, sorry the photos are not the best.

 that has the pink stuff in as well.  Is it just the pictures?  but that doesn't look how I think aventurine would look in lumps.  It certainly doesn't look like the aventurine in my Nason pieces.

Sorry about that, no pink but probably a result of the white balance setting chosen at the time by the camera (and my lack of photographic know how). There is a green/blue blob visible though. This photo may be a little clearer:

Yes, the batch mix for melting contains a good deal of copper bearing materials along with the usual slica and flux ingredients.

[chopin-liszt]

Dropping off to sleep I was suddenly startled into wakefulness by the thought...

"Why does the copper metal not react with the glass to colour it when it is at a high enough temerature to melt the glass?"
Silver metal ions do - and copper is morre reactive than silver......
And I know Ed Iglehart uses old copper wiring to colour his lampwork glass.

When the aventurine is used there is no oxygen in the molten glass to cause it to oxidise. Presumably you have to keep it within glass
