Lots of strange chemistry going on there... an organic acid that looks like an alcohol, 5-valence carbons, ... but the basic idea is sound. It probably started off when people used metal pots to heat the oil; the pots would have been tin, copper, or maybe pewter, any of which would be a rich source of metal ions suitable for hardening the oil. Not so sure why they would have been heating the oil though, as french fries had not been invented yet.

Your little joke at the end made me think. In a museum in Georgia (the country) or Baku, years ago, a saw a peace of leather that was found attached to a wooden molding for the fabrication of armor. I can't remember from what period. I would not be surprised if they have been able to soften the leather to mold with heated linseed oil, and than discovered it gave a nice extra hard finish? all speculation, by the way.

Linseed oil is what Stradivarius used on violins. He complained in a letter to a patron that it took so long for the varnish to dry. Cooking the oil varnish in an iron pot would impart a metal 'dryer' to the varnish, but it still took a long time to completely polymerize. Enter spirt varnish that dries in a few hours and Strad's "lost secret" fell by the wayside. It so happens that linseed oil varnish 'browns' as it ages, which is why a 150 year old Strad 'looks' golden brown. He didn't use leather dye to achieve that 'look'. He used time. Love AvE!

There is at least one linseed oil paint manufacturer around today who claims that their paint is the only paint in the world that does not peel--all synthetic oil based and water based stains and paints peel. I can verify that solid color stains peel, as in 2020 alone we spent over 800 hours in the summer grinding off sheets of solid color oils off decks and siding. Apparently, for some reason, they believe that the linseed melts into the wood because the summer infrared or UV heat, like a semi solid peanut butter fatty acid. Else, it turns to dust that washes off with the rain,. Else it is such a thin and brittle film that the scale problem is not noticed, as high pressure water easily sheers off all of the film. Apparently, the linseed oil film is covered in back mold every 12 months, like most of the old fashioned oils--even when you add packets of mildewcide. Also, it is necessary to add a coat of linseed oil every 7 years to keep it looking credible. Every 28 years, they recommend a serious repaint. (Off topic:This schedule is not much different than any good paint job that uses a high speed 24 grit sander, post rotation water blasting. Except those should be lightly rotated and blasted and touched up every 7 years, since easy and quick to touch up spots happen like snow covered window seals, dormer sides, floors, first 5 of siding in contact with the ground, roof leaks, Plumbing, leaks and condensation Hotspot like un insulated shower rooms. Touchup and wash, every should not be more expensive than a 7 year vinyl siding wash, until the 21st year, where the touchup might be better done via an airless and a fine finish tip, on super peeler houses. .) I am so unimpressed with today's solid stains, that I roll my eyes when un experienced painters believe that they don't peel just like any other paint..... Back in 1990, the solid stain and the 8 year siding paint had the exact same lot numbers and could be substituted in the middle of a side for each other without any difference in aging. Glidden added paraffin wax to their cheapest paint and called it oil acrylic. Whatever the chemistry is on today's solid color stains are, I can vouch they peel and need the same prep as any other paint. They are supposed to be applied thinly, however the thin film is so transparent and looks so bad, that a minimum of 3 coats is usually applied, each coat as thickly as possible because there is just less solids in each can. Letting the solids settle for 12+months, some of the stains have an inch of solids per can, at most. Yet, the paint company want $30 per can. My recommendation is to stick to dark brown or navy blue (maybe dark charcoals) , which is the only pigments that are able to be applied thinly and still have opacity, since thin is the only safe bet. Also, avoid the urge to apply any more than one thin coat. If you can't resist the urge and are not prepared to redo the job every 6 years for siding, then paint, which is the best bet for the 28 year job. I just visited 2 houses I painted 12 years ago. The paint was in pristine shape, however a trim few boards needed a carpenter to reinforce the 120 year old fatigued nails. Only the north side of the cedar shake sided one had about 6 shakes with peeling paint, which is due to former neglect and the shakes loose their hard integrity, so any film of any penetration will not need to peel because the wood just delaminates and you can see wood on the backside of the paint chip, which is how modern paint and solid stains fail. The acquisition of linseed oil is a question, as well as how it fairs over time. I used to add it to outside oils in 1990. The side exposed to the sun, never peeled in 95 years, until they put water based paint on it 25 years after I painted it, because the film was faded and dead looking, typical home owners who think they know more than anyone else, so they second guess everything.

@@Tom-hz9oc Actually, Linseed oil paint makers complain that Sythetic alkyds replaced linseed as the binder, which makes alkyd paints peel, unlike Linseed oil, which just disappears (either chaulks or melts into the wood over time), according to the maker of linseed oil paint. The oil house paints are like 300 USD a gallon and sold in litters. Of course in the US, it is really getting difficult to find oil paints, inside or outside, for houses. Nasty oil primers (very nerve toxic) are available still, as they have not waterborne match, as is lappy flashy oil metal paints (too short to properly paint a door without lap marks, even goosing the oil based paint). Floor polyurethanes are still available, I guess, because the waterbornes do not have the adhesion or build that the oil poly's have. Quarts used to be available but that dried up in the past year or so. It is no big loss, as SW alkyd urethane rivals any oil, and oils never held up in sunlight outside and mildewed fast. However, long oil primer outside was a useful additive to waterbased primers at 20 percent to get infrared peel resistance and oil like adhesion, and thickening build of the oil. If not in direct sunlight and not on a leak puddle area, old 1920s lead oils are nearly impossible to strip with Infrared, or chemicals. Only flame level temps get them off, or titanium blades spinning at 10 k rpm and a good water vac and hepa. I am not a fan of heat stripping old lead as the lead in the powder causes a rash on my face, while I can contain the dust from grinding it off.

Yeah, he's a little off on the chemistry. Where it creates double bonds with a neighboring carbon, there would be no bond to a hydrogen atom. This is what makes it unsaturated; the oil is not _saturated_ with hydrogen atoms. There's little "gaps" along the chain where there's no hydrogen bonded to a carbon. This is why the unsaturated oils go rancid faster; the points where the hydrogen atoms are missing are more easily attacked by oxygen.

Unboiled linseed oil does in fact polymerize when exposed to air, it just does it much slower (and it's higher viscosity, boiled has some volatiles added to get it easier to brush); the boiled stuff is just more convenient, and there's a nice continuous path of development from "this oil works well as a finish" to "if we do this to it it works _really_ well and quicker for a finish".

I too have many cast iron pans from around 1900. However, I had trouble with flax oil becoming too hard and then flaking. Canola oil has made the best surface for me. But I've switched to using a product made by Blackstone the griddle maker. It's a proprietary blend of palm shortening/oil, beeswax, canola oil and soy oil.

As guitar player and occasional builder i enjoyed this. I use all sorts of finishes and ive always been interested in the evolution of polymerized type tung oils/Tru oil from linseed oil. Every now and then when i have a new tool that needs a finish but isnt a nice enough tool to warrant a poly finish i just wipe on some boiled linseed oil. Tung oil or Tru oil would certainly be more ideal but boiled linseed oil is cheap and i always have some lying around. Again, cool video!

I am a professional painter and decorator and pride myself on being able to explain to my clients new technologies and products being developed by the painting industry, so my clients get the best possible return on their investment in the work I do for them. Preparing the substrate, repairs, multiple steps in the application of the finish, etc. is about 80% of the total cost (i.e.labor), and somewhere around 10-15% (on the cheap side) and maybe 20'ish% for the best/most expensive products, I always try to encourage clients to use the best materials they can.... Seeing how the labor is not cheap and I'm doing the job anyway. I've never been able to really understand exactly, or more accurately I guess you'd say, what is happening chemically, I've always felt like I could not really understand what it was that I am trying to explain,nor personally I understand.

1:57 some minor mistake: when you have a double bond, the molecule has two less hydrogen. That's why you can hydrogenize it to make it into a single bond. Carbon usually forms 4 bonds afaik. Please correct me if I'm the one mistaking.
@PeregrineHawthorn2 жыл бұрын
No, you're correct. Carbon, under normal circumstances, forms exactly four bonds. One double bond between carbons means that those two carbons each have one fewer hydrogen. This allows the chain to twist and bend, letting it be liquid at higher temps. Pushing hydrogen into those chains straightens them out, making them solid at lower temperatures, making them easier to store and ship.

@HoosierRallyMaster2 жыл бұрын
Do you mean refrigerate the pan or refrigerate the bottle? Yes, the bottle of flaxseed oil needs to be refrigerated to prevent it from turning rancid (the fishy smell.) That smell is the oil turning rancid. When one of those double bonds breaks and doesn't find a neighbor to cross-link with to form a polymer, then part of the fatty acid breaks off and floats away as a free radical. That is rancidity. Refrigerating and keeping oxygen away by sealing the bottle slows down the chemistry. If you are getting the smell on your pan then the best ways to prevent it is to make sure the oil is wiped on as thin as possible and to moderately heat the pan each time you apply fresh oil.
@rustyshaklferd18972 жыл бұрын
@@HoosierRallyMaster thanks for the reply and info. I mean the fishy smell happens when I season the pan with it. The oil is new and smells fine in the bottle.

Flax/linseed is actually terrible for seasoning your pans. It polymerises very well, but it creates a very flaky layer, which is prone to lifting off.

Ive come up with a method to make wood pretty weather resistant using linseed oil first apply ballistol, let it soak for a few hours(preferably 1-3 days), wipe off exess and let it sit for a while ballistol protects the wood and soaks deeper in to the fibers than linseed oil, but it isn't very moisture resistant on it's own you can use scotch brite to "sand" off fibers that started sticking up after this apply a heavy coat of linseed oil, let it soak for a few more hours, wipe off excess let it sit for a few hours, finally, apply a thin coat with a piece of disposable cloth(bounty works fine) let it cure for a few days in warm sunny weather tools I've treated this way can stay in perfect condition for many years even if they are left outside in rain and mud after 10 years you may need to reapply some linseed oil if cracks are starting to form on the wood from it drying out our oldest tool(a digging fork) had the same handle for well over 30 years the wood has gotten extremely hard and tough when the (cross bar? top handle?, you know what I mean) broke off it was nearly impossible to get a screw started ballistol can cause the wood to shrink a little, so it might be a good idea to do this before you mount the handle it might be a bit time intensive, but even with heavy use and abuse you can expect the linseed oil to hold up but if you put in that much effort it certainly will pay off to pick the proper handle with straight grain, there usually is only one, maybe two of them available in a hardware store, so choose carefully they all cost the same, but putting in a little extra care and time will pay off in the long run.

THANK YOU! I accidently burned of the seasoning on my cast iron pan. So, I've been seasoning it with olive oil. But, now I know I was not using the right king of oil. I just thought cooking oil is cooking oil. I didn't know they were different. However, I'm not to keen on oils other than olive oil. Apparently, canola oil and other oils may not be healthy. In fact, during the processing, the oils become rancid. They have to add perfumes in order for you to stomach the concoction. But I think I can use it on a pan since it will only be a coating. I refuse to have cookware with Teflon. When teflon was first developed, people started realizing their Budgies were dying. Why? Because on first use, there was still some unprocessed chemical on the pan. When you heated it for the first time, it gave off a toxic gas. The gas wasn't a problem for people, but the gas killed the family pet bird. It was just like the canary in the coalmine. The fixed the problem by treating the pans at a much higher heat in order to burn off any residue teflon chemicals. I don't trust teflon because it flakes off (even if you aren't using metal on it) and you're ingesting teflon. I love my cast iron pan. better than any crappy teflon pan.
