I'd like to thank Jabberwock, MrTsquare, and Sean_the_Nailer for their recent and informative posts. I'd like to make a couple of points re the recent comments.
Actual glasses, such as spun glass, don't have a fixed chemical composition (glass refers to a material's lack of crystallinity), but they are generally totally inorganic (vs organic like plants, animals and their by-products such as plastics and rubbers). Typical glasses are likely to be chemically stable for millions of years, since glass is extremely resistant to chemicals (which is why so many chemicals are stored in glass bottles). I would like to know, though, how easy it is to tie a small knot from a strand of angel hair? Knots always help when glue might fail to hold rigging in place.
The diameter of human hair is actually quite variable (by over a factor of ten). Ultrafine, at least to my mind, implies a diameter of not more than about 0.003 inches or 80 micrometers (microns). 80 microns is close to the "average" diameter of human hair, so average or finer hair would be ultrafine, but coarser hair would not be (with respect to this forum).
I have an "infinite" supply of 0.003 inch nylon monofilament thread (miles), and it is much finer than a stringed instrument string unless the string is woven of finer strands. The problem with unweaving strands is that sometimes the finer pieces are proper threads themselves, but more like thread fragments, and when you try to separate them out, you don't get particularly long pieces.
