As soon as I read the stuff, as there are many pages on varnish, I will post
the info. If it is worth the article, I'll send a copy to you. However, my
bet is that after I plow thru the pages of formulae it will say something
like "this is similar to soehnee". Suffice it to say, varnish in the 1860's
was a biggie, because everyone was varnishing their glass plate negs, and
then experiencing problems with yellowing and bubbling and such. This is a
very cursory read, but when I hit upon the first varnish article thinking I
had come upon gold (1867), copied it, then a whole bunch more appeared in
those years 1867-8. I have 1860-1 on microfilm, and then the collection is
void in 1862-5, then picks up again every year thereafter. I do remember
that the problem of cracking was alleviated by the addition of some oil to
the original mix.
