The question I have is how to tell if this is made from cotton or rayon? I did a burn test and the threads burned quickly, left some ash and did not appear to melt. I was under the impression that rayon burns like this as well so I am no farther ahead after the test, except that I know it isn't polyester or some other newer synthetic.
Yes the material is soft and floppy so my guess is cotton but that is not the big problem as I see it. I was checking out a new postcard that I just got in the mail with a black light and was happy that the pc didnt glow at all, BUT when I looked over across the room this eagle was lit up like it was christmas.
So now I really have my doubts, if it is cotton there is NO reason at all for it to glow but I am unsure if white rayon will or should glow.
Here is a poor pic but you get the idea. The blacklight was held about 3 feet away and the eagle is in a ryker mount behind glass.

Will Rayon glow? Not a light or a reflection type glow, but a bright blue glow.
Sorry for not replying sooner but I have to pay for this stuff somehow and working seems to be the only way.
I know about how phosphates in detergents can make an item glow, but I always thought that it would be more of a subdued glow. This eagle glows almost as bright as a piece of paper and as bright as a 'new' white t-shirt (both used for comparison when I tested it). It is very bright and IMHO too bright to be just from detergents, unless it was washed numerous times which does not make much sense.< assuming the glow would increase with subsequent washings.
This brings me to the rayon issue and the question if white rayon from this period glowed under a black light? Someone out there has the answer.
I doubt I can be happy with this in my collection now either way, but I would like to know about the rayon glow question for future reference.
Hi Al,
sorry but when i collected cloth (stopped about 5 years ago) i never blacklighted any of my items just did not belive the test stood much ground, (my personal oppinion) and relied soley on touch ,smell and gut feeling,so sorry i cannot comment on your blacklight test results.
