The use of lead in everyday objects dates back to the ancient Romans. They used lead in makeup, as an additive in food and wine, in pewter dinnerware, and many other items, including paint. The inexpensive metal was even used in the pipes that transported water throughout the Roman Empire. Lead continued to be used throughout history and into modern day. So it was no surprise that no one thought twice about adding lead to paint. But why did manufacturers add the heavy metal to paint? What purpose did it serve?

I was exposed to lots of heavy metal in the 80s. Now I can't hear high tones well. Oh well, it was worth it, they were great concerts.

Underrated comment

Interesting fact, lead is added to electrical solder to prevent tin whiskering and tin blight and is necessary for electronics where reliability and longevity is important such as spaceflight and medical implants. No substitute has been found except cadmium which is more toxic than lead. Use of lead free solders is the main reason why modern consumer electronics don't last as long as they used to, tin whiskering and tin blight will kill modern electronics usually within 8-10 years.
It also blocks emf... and thats why they banned it
Cole Marie , makes you wonder...
I believe that the Government scared the public into repainting their homes with lead free paint knowing that the alternative would not protect homes from thier 5G towers they are putting up everywhere!!
Bruh
Programming Cafe 😂😂😂 I was about to comment the same thing
Cole Coley. That's exactly the reason. Lead paint It's very cheap and lasting compare to the special insulation primer paint against the EMF/5G
Exactly. 5g won’t work on a house covered in lead.
Reading through comments in this thread, and seeing so many misperceptions, I feel compelled to write another post adding some information:
Paint is mainly composed of pigments, binder and vehicle. The purpose of the pigments is to cover a surface to protect it and also give it a color. The purpose of the binder is to hold it together, form a film and adhere to the surface. The purpose of the vehicle is to make it fluid and easy to apply. (What is used as a "thinner" is often the same as the vehicle.)
Lead existed in old paints only as pigments. It is thus not a function of the binder, nor does it affect the handling of the binder, as in brush strokes, etc. Switching the binder from whatever to to whatever, including "Vinyl" paints or "water based", doesn't automatically make them lead-free. The choices of pigment and binder are separate and not interdependent.
Lead pigments does *_NOT_* make for particularly durable colors! Such claims are utter hogwash and myths. All the principal Lead pigments are impermanent. Quite the contrary, a strong motivation to replace Lead pigments with others, even if they were more expensive, was to get more durable colors, particularly for outdoor paints like signs and car paints.
However, Lead pigments do affect the durability of one class of binders, those called 'drying oils'. "Drying" oils do not dry. They polymerizes and become hard, by oxidizing. Eventually, as time passes, they get harder and harder, and brittle, and start to flake. Lead pigments delay this flaking, and thus got a reputation for durability, and became preferred for primers. This is probably where this persistent myth of durability originated. It ceases to be a factor when choosing a different binder. The Lead pigments themselves and their colors were certainly not durable at all. Lead pigments were, by any modern comparison, *_utter_* *_crap_* . And while some modern paints may fail in some applications they're unsuitable for, the notion that a "Lead paint" would have done better, is just fantasy and urban legends.
Thank you unbearded Simon of years past
@Today I Found Out I'd like to request a lead gasoline episode please.
BABY SIMON
You thought this guy was a stud back then, now he's oozing with beard and sass.
I'm going to line my walls in lead paint
Good thing I don't and have never went around licking the walls.
+Brian H Well it's alright for some.
Bad Cattitude Thanks Willy Wonka.
TL;DR: Lead compounds were used as paint pigments because they made for really great paint. The only problem comes years later when it chips off and little children eat some of it.
At first why Johnny Sins you do like him
Bull poop! Lead paint was virtually non-existent in houses during the 1970's. In fact, vinyl paint was the paint of choice during the 1960's. Don't you remember all of those commercials about cleaning up with soap and water? No, your way too young and don't even know that a lot of homes built in the 1050's are also lead free.
ur too young to even say bullshit
@@Jared-by8oq if you were born in 1900 you're absolutely right.
I like this shirt on you. You look very friendly with it on you. For some reason I'm not a fan of the vest you sometimes wear.
+errorsinconduct Ha, thanks. Sometimes it's cold, so I wear a jumper/vest :).
Love me some good paint chips to snack on
Lead wasn't "added" to paint. 😒 Almost all the brightly colored pigments they had available in quantities and at reasonable costs were Lead compounds. These Lead pigments were the 'paint'. Not additives. Everything else was added, serving the singular purpose of having the Lead pigment covering the painted surface. The premier yellow pigment was 'Chrome Yellow', a Lead pigment (Lead chromate). The premier red pigment was 'Minium' aka Red Lead (Lead oxide). The premier green pigment was 'Chrome Green', which happened to be Chrome Yellow (still Lead chromate) tinted with Prussian Blue. The premier blue pigments were Lead White tinted with Prussian Blue or Permanent Blue (an ultramarine). And so it goes on.
Chemical industry eventually produced alternatives. Long before USA most shamefully didn't ban lead paints until 1978 😡 . The usual corruption. 😒
@Thomas Venam Just be afraid and aware of any old paint job that gets burned, grinded or sanded. Stay well away, and refuse to work with it yourself.
If you got poisoned as kid, well unfortunately you probably did, and so did a lot of us. Not just because of the paints, but also because of Tetraethyl Lead being added to gasoline, to raise octane numbers, for many years.
Not much we can do about it except staying as far as possible away from lead for the rest of our lives. Another danger: Lead pipes and tin-lead solders in plumbing.
@Thomas Venam No. The lead that poses a threat to you, is the lead that you might ingest, through breathing or food and water. Handling lead metal is almost completely harmless, unless you lick the oxide off your hands or sniff corroded lead. So calm down.
I don't know if mobile phones really contain lead, and I don't understand what the function would be? But if it's true, it only poses a danger to those who manufacture those components, or those who recycle scrap from old phones.
The plumbing of drinking water supply, do deserve an examination. If you only wash in it, don't worry.
Also why the bottoms of boats were/are often red.
For sign painters lead in the paint acted like ball bearings for paint. It helped the paint flow off a lettering quill better. Sign paint would last 10 to 20 years when it had lead in it. Today's sign paint has dozens of extra chemicals in it to replace the lead but still has a very short life expectancy compared to it's leaded cousin. I've seen some colors going bad within 3 years. I wish they could have left the lead in sign paint but unfortunately instead of selling it to the trade only, paint stores sold it to whoever wanted it and law makers wanted the lead out of everything. Lettering quills for water based paint has improved, but lettering with an alkyd enamel is still the best. Too bad the paint isn't.
Yea but I would rather keep a neurotoxin out of everyday things.

Simon, have and will continue to enjoy your great videos, just one criticism. Didn't like your use of what appeared to be a photo of someone who has down's syndrome.
Lead Paint: delicious, but deadly.
