Re: [Histonet] 4% paraformaldehyde all over again

From:John Kiernan

   There  is no such thing as 4% paraformaldehyde. Nobody can sell or
   us=  e  such  a  non-substance!
See Histonet archives passim ad nauseam.=   (That's how the ancient Romans said, in 3 words,= "on and on, until you want to vomit". Latin is concise= !)
4% formaldehyde is a real solution, and = one of the ways of making the solution is to heat 40 grammes of = paraformaldehyde in a litre of water, with an alkaline catalyst to sp= eed up the hydrolysis. Paraformaldehyde exists only as a solid substan= ce, which is insoluble in water.  All this has been in all the textbooks and manuals for 40+ years.
