Everything is recycled. It's only a question of defining the timescale.

Look for that, it is a recycling byproduct:

Tickle it. If it blushes and giggles, chances are it's virgin.

I am satisfied with the paper I have been using and won't even worry if it does contain some recycled material.

According to a recycle Fundy the process of cleaning the ink and traces of plaster of Paris is to costly to produce 100% recycled paper.

On one of the packs I have is a note that it contains material from a managed other source.

Classification of strings.

A-string = pure

B-string = not so pure

.

.

H -string = filthy

Quang Yo, In my experience, the length of fibers (fibres) will be shorter in recycled(reprocessed) materials due to the effects of processing. I won a very expensive ruthenium plated pen from Tiffany's once by selecting the recycled sample of newsprint out of a tablet of virgin newsprint. it was clear to see- the virgin newsprint had much larger "chunks" or grains /fiber structure of inclusion material. The recycled, having been processed additional times, had no large "goobers" they had been digested in the multiple steps.

This same reasoning should apply to paper string, look at fiber length. Virgin material should have longest fibers, recycled, on average, much shorter.

If you use 30 samples your average will be statistically valid use student -t test for significance between averages.
