Macfred, I've seen that sort of setup before!

Yes, I'm sure you did ...Macfred, I've seen that sort of setup before!

But I bet you never saw a Bunsen burning directly under the glassware like that.
I loved my school’s lab. I spent a lot of time there and I miss it.
That's interesting. I thought Ferrania claimed that, as a motion picture film, its intended developer was D96.My initial study DID reveal is that Ferrania at that time recommended their R 18/a Developer. with a time of 8-10 minutes for the still film, and 6 to 8 minutes for the 16mm film (both at 20C) I went to make a table of the formula of R18/a, (found in another book I bought, in Italian showing the 1958 range of Cine films) and smiled when I realized it is identical to D76.
d76 was originally a motion picture developer.That's interesting. I thought Ferrania claimed that, as a motion picture film, its intended developer was D96.
Real developing laboratory? You mean a darkroom?
I managed to obtain from an ABE-Books bookseller a copy of a Ferrania catalogue from 1965, which does have some real data sheets on P30 both still and 16mm size from that time.....
I was employed as an analytical chemist in the early 90's by Amana Refrigeration. Before they hired the "Chemist" they had a bunch of mechanical engineers with a half a million dollars to spend on laboratory instruments. The FTIR guys were in the "golden era" they sold management a really amazing unit must have set them back 250 grand, the rest was spent on gas chromatographs, auto titration stuff etc.Well, I have a good cartoon of "How Kodak Makes Film". It was posted elsewhere and I can't locate it right now, but it is in the book. It was posted all over Kodak Park by an anonymous artist.
We only used Bunsen Burners for heating Melting Point Tubes. We were past using them by my time, but I did learn.

Needless to say I shook my head and said great! Management thought you could put any matter in the universe into the FTIR it would search it's "library " and spit out an exact identification. The most reported answer when analyzing esters was Nutmeg oil!
We had a problem with contamination in compressors . I bought 1 piece of equipment, a Mel-temp melting point heater, thermometer, and magnifier glass $200. That's what I used to confirm what the suspect compound was. It was a type of ester wax, dissolved in ester oil for the compressor. Trying to identify it with melting point was the only practical way to do it.
Needless to say Amana was bought and sold 3 times, it's now the last refrigerator factory Whirlpool runs in the USA.
I loved gravimetric assays. I worked as a bench, analytical chemist for about 12 years in 70's and 80's. The most fun was the classic wet chemistry assays. I was lucky, we had a single pan Sartorius balance. My Dad used an Ainsworth Chain-O-Matic twin pan. That was pretty nice right after WWII. I still have the Ainsworth, nice set of weights, Ivory tipped tweezers so you didn't harm the weights . I'm contemplating a mid-twentieth century lab in a spare room. Drives me crazy now that I'm retired that I don't have access to equipment. Does anyone run Kjeldahl nitrogen assays anymore? I bet I ran 5,000 over the years. Now days people stand in front of machines all day, boring.These days we are in the mass spectrometry golden era.
By the way, your story reminds me of a story my dissertation advisor once told me. There was an older faculty member. (I don't recall the name of the school where he worked.) Part of the PhD requirement was that the student had to present a proposal that was unrelated to their PhD project. Many students would come in with very elaborate proposals. This old faculty member would then say "just show me something you can do with a Mettler balance."
I never ran the Kjeldahl method. I ran some atomic absorption spectroscopy, a little UV/Vis spectroscopy, a little gravimetric analysis, and a lot of mass spectrometry. (I currently edit a journal in the field of mass spectrometry) I did a short stint in a routine analytical chemistry lab before I went to grad school. In grad school I specialized in physical chemistry, and stayed in that field for a few years. Then I drifted into analytical chemistry and instrumentation design. For the last sixteen years of my career I specialized in clinical chemistry, which is essentially analytical chemistry applied to the analysis of medical samples. I became board certified in that field during the final six years of my career. Interestingly, Richard J. Henry, who is known here mainly for writing a book on photography (Controls in Black and White Photography) was also a very prominent clinical chemist who wrote a very influential textbook in the field of clinical chemistry.I loved gravimetric assays.

before the winter solstice... ->What is the definiton of "This fall" anyways? Before 23 Dec?

Well, the definition of fall/autumn has stopped being relevant as, unfortunately, the shop page now says "Returning Early 2019".
