    Re: "Blinged Out" Conqueror

    I don't think it really shows in this pic, but this joseph's coat is loaded with aventurine in the green. I bought it on eBay - the seller called it a peewee and so I bid without questioning the size. When I received it it was a bit over 1/2", but the aventurine was so stunning (and how often do you see aventurine in handmades?) I decided not to fuss over the size discrepancy. Oh, but wouldn't I kill to have this in a peewee! It's a true Joseph's coat - there is no base color as on an onionskin - it is all closely packed opaque strands all around. When the seller told me it came from a solitaire board (he was breaking up the full set of matching marbles to sell one-by-one) my heart skipped a beat! Surely one is a peewee, but alas, no such luck

    Sweet marble though - had to make room for this one. Alays room for one more, right? :biggthump

    I have seen what i believe is intentional aventurine ribbons in handmades. Sold them for a good price!! Peace,Galen

    I've been puzzling over this conclusion.

    Aventurine can be accidental; this seems to be established. So the lack of it in CA marbles seems more of a clue that Fiedler knew how to avoid getting it, than a clue that it is not actually accidental after all.


    If the glass formulas Fiedler used were not ones which contained the elements which turn into aventurine, then that would explain the lack of it. For example, did he use chromium oxide?


    Or Fiedler's expertise at glass-making might have precluded the sort of accident or experimentation which might have resulted in unintentional aventurine. For example, if he did use chromium oxide, perhaps he always made sure to have high enough heat and/or enough fluxing agents to accomplish what he wanted without the issues described in the Libby-Owens-Ford patent.

    Pulled from another thread on a certain forum not so long ago on the subject of bricks the microcrystalline (copper) in bricks came up...

    "Oxblood - a red opaque glass containing copper particles of the same order of magnitude as the wavelength of light. Crystals of this size produce opacity, but are not large enough to produce metalic gloss, ie, aventurine."

    For Goldstone (Aventurine)...

    "The most common form of goldstone gives the illusion of being reddish-brown, although in fact that color comes from the copper crystals and the glass itself is colorless."

    Going by that, and the fact that modern marbles (J.O.K.E.R.) have been produced containing both types at once, they would seem to be pretty similar types of glass with crystal size being the main difference. Why don't we see any "accidental" MFC Aventurine or a lot more "accidental" Peltier oxblood? I know a certain lurker around here might know the answer and might shed some more light onto the original makers ability to control their results.

    I am no expert on this, but it seems to me that Briian Graham should get involved in this conversation since he makes oxblood using an old German formula. He often shows a piece of his oxblood cullet that has gone too far in the glass making process which has "aventurine in it. He explained it as part of the process.
