[LUTE] Re: How to distinguish carbon from nylon.

2012-11-03 Thread William Brohinsky
I am no expert on plastic strings, nor am I a degreed chemical engineer. I have had a six-month romp through carbon chemistry at work, and can suggest a few things. First, Nylon and 'Carbon' strings are both carbon, since carbon is the major constituent. Nylon used for strings, iden

I made a test: I put a piece of an old "rectified" Pyramid 0.70 nylon string to water, and it sank, slowly but sank anyhow. So it is heavier than water, and thus it must weight more than my 1000 Kg/m3. But I have always calculated with 1000, and shall do so in the future, too... ;-) Arto

Nylon tends to be a bit more opaque than carbon but this really only shows with thicker strings. Best advice is: put it on your lute see what note you get with a certain tension. Compare to other strings of same note and tension and the thinner string will be the carbon. BTW there seem to be ma

Is is possible to distinguish reliably between carbon and nylon if the string's packaging is not available? I've seen a knowledgeable person rub the string, but I don't know whether he was listening to the sound, feeling the texture, or judging some other aspect. To get on or off this list se
