Please feel free to disseminate the formula as you see fit.
Notes:
1) Temperature is 68 deg. F
2) Quantities added are to 1 liter.
3) Sulfuric acid is listed as "concentrated". My recollection is battery acid
is about            16%. I always had acid in the lab anyway but now I buy it
at a lab supply house  (in Burbank, CA  "Tri-ess" Student Science Supply).
4) The addition of sulfIDE can be considered optional. With it you get a nice
sepia tone.
