I was going through my list of usual blogs that I frequent when I came across a "recipe" if you will for Formaldehyde from 1936. I have to thank my blogger-bud MSW, author of Another Day in Paradise blog for supplying me with this information. I don't think that I'll be mixing this formula myself sometime soon however it is good to know that I don't have to rely on the corporations who manufacture this stuff if ever I'm in true need of it and they can't or won't supply it. The chemical composition of the 1936 Formaldehyde and the current Formalin is slightly different but I imagine with fine tuning the results could be similar. The only thing I have to consider is whether or not I want to keep the individual chemicals in the quantities necessary to brew it on hand. Once again, thanks MSW!
