you did things correctly. i used to do this for 5 years at gossner foods in Utah in the whey and cream prepossessing. we took these samples every 20 minutes of production. while this is a very old cast item we used a less fancy more modern from the 90's one but the process is identical. we are supposed to do 2 of them at a time and thus why yours has 3 areas with 2x in them. 2 for redundancy to get a more accurate average (hence your discrepancy form the store milk) and if you do the math. every 20 minutes, takes 20 minutes to do the job, you are doing 3 every hour. this tool would have been in constant use while the cream fat separator is in production from the milk / cheese was in production. some person was probably turning that thing for 12 hours at a time. most plants never shut down. if this was a single vial or dual then i would say that it was for a small farm but a 2x3 unit like this would be in use for at least 12 hours every day non stop.

On their farm, my grandparents had a milk fat tester (pretty sure the same model), a hand-cranked skimmer, a motorized butter churn, and a staggering collection of glass bottles and oddments, but when I saw them, they were all covered in ages of dust and barn grime, so no idea if any of them were cobalt blue. I never knew how the milk fat tester worked and my grandfather only ever said it used sulphuric acid in a kind of tone to warn me off it. That was 50+ years ago.

A Two-Fer! A tool restoration and a science lesson from a different era. This was Old School Cool! Thanks for the great video!

I was born and raised on a dairy farm and operate the same dairy farm today, I'm 64 years old and can remember the DHIA, (dairy herd improvement association)tester arriving on our farm and after milking set up a similar centrifuge in our milkhouse and doing the same test for each cow. Her centrifuge held at least 50+ bottles. The testers were usually retired dairy farmers or their wives and they handled everything without gloves using open ended pipettes and they sure weren't shaking like that. Shortly after that DHIA started sending the samples off to remote labs where the samples were run by newer single step machines and much faster. Now it just consists of a probe, don't ask how it works I haven't got the foggiest.

My grandfather ran a "cream station" on Saturdays in Paragould, Arkansas in the 1950's. Farmers would bring their cream to us and we'd use this test to determine butterfat content and then pay the farmer according to total volume times a factor based on the test result. They'd usually bring in about a 10 gallon can. My grandfather was an agent for a dairy in St. Louis. I was about 10 years old and developed an interest in chemistry from those Saturday adventures.

My dad's first job, back in the 40's, was helping to test milk from local farms for fat content. They found some farmers were boosting the fat content by adding used motor oil.

It's a banger. Got pulled over playing it by the police cause my stereo was too loud. I said, "Hey copper, whatya zinc?"

The black part is carbon. When you add sulphuric acid to such organic materials everything that contains water molecules like the sugars in the milk gets dehydrated and the carbon is left behind. For example is you add sulphuric acid to pure sugar (sucrose C12H22O11) you'll get an exothermic reaction that will leave behind a sort of carbon sponge

As usual I love all your videos. I'm sure you made the original makers of this tester proud making sure to keep it the same color as you lovingly restored it. You always respect each item you restore and make it shine.

Socially distant garbage on the floor becoming emotionally distant. Extremely relatable.

I paint and I'm a bit of a history nerd - There where basically 5 common blue pigments available at that time. In order of age they would be Indigo Prussian blue Cobalt blue (cobalt(II) oxide sintered with aluminum oxide) Synthetic ultramarine Cerulean blue (cobalt(II) stannate) While I doubt that looking at this video, I'm getting a perfectly accurate recreation of the actual color, that *really* looks like synthetic ultramarine to me. Because of risk of the colors not being reproduced on my screen 100% perfectly, I would hedge my bets and say it *could* be a variant of cerulean though but unlikely. Natural indigo has a much greener hue and was not common for this sort of application. Smalt was still around but had largely fallen out of use. It has a very pale desaturated look to it. Prussian blue is *very* dark on it's own. Since you found no lead, it's very unlikely to have been cut with white to brighten it. Cobalt blue was very expensive. Not as expensive as *natural* ultramarine but still pretty costly. It was largely reserved for fine art and luxury goods. Cerulean blue would have been pretty new at the time. Basically, once synthetic ultramarine became available, it was *the* blue of choice for paint for quite a long time. That boils down to a mix of cultural and economic factors. It was cheap but it was still viewed as the color of royalty.

I worked for a distributor to the milk-testing industry and centrifuges were one of our items. He said he used the “Babcock” method/bottles.
