You're probably thinking of Fireworking.com  I still find the projects and compostion database on passfire better, but the forum community has largely migrated over to fireworking.

The term NC lint really refers more to a purity than anything.  It's meant to describe NC in it's pure, unprocessed state.  This is opposed to NC already processed into smokeless powders with additives and such, which would interfere with colors.  One good source tends to be nitrated microcrystalline cellulose.  It burns hotter than normal NC.  It's also much easier to work with.  I don't know if you've ever tried to screen short fibers, but it's a pain.  There are a few patents on these type of compositions.  Typically you can find them by searching for low smoke stars.  I included a couple.

Getting real, authentic Saran (made from saran resin) is important for this to work right.  Using plastic wrap made from polyethylene doesn't work as well.  Maybe it's easier for you guys in Europe, but real saran wrap is getting more difficult to find in the US.

Somewhat related, but there is a book by the Japanese artist Bunpei Yorifuji on the elements.  It's a little weird and quirky, but it's an interesting item.  He has personified all the elements.

I think this quote from Davis sums things up nicely.

"The products of the burning of black powder have been studied by a number of investigators, particularly by Noble and Abel, who showed that the burning does not correspond to any simple chemical reaction between stoichiometrical proportions of the ingredients."

If you look at the analysis of the burning mixture in Davis, something sort of interesting is noticed.  Of the solid products (55.91% of all combustion products), 8.74% is sulfur.  This means approximately 50% of the sulfur in the formula is ultimately unutilized. 

If anyone in charge here would like to check, I'd be happy to provide my collection of known IP addresses used by Anyka, Ushie, etc.
