Here is the best source of info about making solar eclipse viewers

http://www.mreclipse.com/Totality/TotalityCh11.html

Note that there are two kinds of black and white film, and that only one of
these two kinds provides solar eclipse viewing protection. (One uses silver
dyes the other uses organic dyes.)
