No test was done for chemicals, either in my first tests or in the ones that David and I later did together. We outlined the tests we did. The results did not prove that nothing was done to the card, but they showed that nothing was revealed by the tests we conducted. Personally, I have a hard time believing that 104-yr old ink could be removed by chemicals without leaving any trace of the lettering, but if someone wants to show evidence that it's possible, I look forward to seeing it.
There are additional tests that can be done to cards or to mounted photos, but for most of them expense and possible damage to the item has to be considered. A good example is the infamous cdv that Saco auctioned, that was discussed here extensively. I was able to show that an albumen photo could be soaked off of a period mount and then reapplied to another, using the same glue from the original print, and leaving no evidence of tampering....other than water content in the item. Such a test would be worth conducting for a high-value item such as the aforementioned cdv, but not for less expensive items. Chemical testing for T206's is probably less-expensive of a test, but not worth doing for low-value items, unless someone knows something I don't, and that's very likely.
