Doing some quick bleach tests to see if the gold fabric I bought two years ago actually is silk cause it didn’t feel like it, and there was some concern about the fancy blue “silk” I bought over the weekend. I used a scrap from my green poly 1927 day dress as the control subject. The green poly never discolored nor lost integrity. Meanwhile the gold broke down easily with some agitation, as did the blue plus it turned to an ugly yellow and brown after 20 minutes.
Friendly reminder kids, do not bleach your silks nor your wools unless you want to see if they’re true animal fibers and not fakes. If there’s a stain try brushing it off and taking it to a dry cleaners.
And yes I did do a burn test with the three of them prior, but I still had some doubt. Like “okay but what if the weave made a difference” or “what if this is just high quality poly???” Bleach tests shut those doubts down conclusively.
