OK everyone, as promised, here are the two assay results I received on the Twag v1, one dated 05/25/11 and one 06/03/11.
On the assay dated 06/03/11, the Eclipse and Twag v2 are also listed under the v1 results, as I wanted triple confirmation (and from a different lab I originally used) that Twag v2, is, in fact, what was promised to me.
As everyone can see, there does seem to be a problem with
some of the Twag v1, as the purity came back on the 05/25/11 assay as 91% pure and 93% pure, while the assay of 06/03/11 came back as 99% pure. So,
some, but not all TWag v1 seems to be not as pure as was promised to me by my vendor.
The assay performed on 05/25/11 was done on a piece that Craig sent me that had exhibited the odd “green striping” issue. As one can see from the image of the assay above, the wire was tested twice via ICPE and the results were 91.149% silver and 93.196% purity respectively. Due to the results not quite lining up with the other assay from the UK that was posted earlier in this thread, I opted to send some of v1 I have left here that had not turned green for a test, so I could try and get a handle on what is going on here; I needed to determine if this is/was a batch issue, or an issue with all of the v1.
The second assay is the one that is dated today, 06/03/11. As one can see, this sample of the v1 is 99% pure. One can see the methodology used as fire assay, or “fire assay with an ICP finish”, as the assayer explained to me.
So, my statement on the matter is this:
It appears, at this point, that
some, but not all, Twag v1 has a lower purity than I was promised by my vendor. So,
some, but not all, Twag v1 may exhibit the “green striping” issue. If your cable is exhibiting the “green striping” issue, please contact Craig for replacement. But, again,
not all of v1 appears to have the purity problem, and so therefore should not exhibit the “green striping” issue. So, if your cable looks fine now, it should stay that way for a long time to come, and continue to serve you well long into the future.
I apologize that I let a batch get through that apparently has some problems. This will never happen again, as every new batch of cable I get made,
that I state a purity percentage for, will have an assay performed on it before it is released to anyone. If I state a purity percentage, I will have the documentation readily available for anyone who wants to see it. Not all my wire will have a stated percentage of purity, but for that wire that does, feel free to ask for a copy of the assay.
From the very start, both Craig and I have stressed that we will take care of anyone who is having a problem with their v1. This is still the case. If your v1 exhibits any “green striping” issues, please contact Craig, and he will work with you to ensure that you are happy.
