Cody is formally educated in geology and chemistry. He knows what forms of a substance are toxic, which ones are not, and the proper handling of these substances. Because he knows what he's doing, he can take appropriate precautions to confidently do things that may be borderline hazardous. On this channel, he's just a guy with a camera trying things out. He does NOT know what is hazardous and what is not, so he must be extra cautious in handling toxic substances.
At first, I thought you were referring to gallium arsenide diodes, which I believe people do use in at least modern crystal radios, but sure enough, galena is one of the crystals used in crystal radios. Learned something new. Thanks.
He's going to have to smelt copper and draw it into a wire to form the antenna and the coil. This is an excellent episode idea for his next series: explore how much sooner we *could* have had certain technologies. Everything we needed to make radio broadcasts existed by 2,000 BC, including crystal detectors, copper coils, shellac for insulating the wires, magnetite for making the speakers/microphones, and batteries to power transmitters. The finest artisans of ancient Greece could definitely have made a vacuum tube.
@@herzogsbuick I thought the same at first, but then i remembered a Cody's lab video, where he shows a vaccum pump that only uses mercury dripping through a glass tube. upon research is called "Sprengel Pump", so they could in theory build a fully functional vaccum tube at the time
"I've surrounded my mouth in mercury to stop the molten lead from burning my mouth, along with that i have some solid sodium to have an easy way out in case of an emergency " - The insane(er) version of Cody
Even as of the 1980's, house drapes - the ones that hung to near the floor - had really soft (very malleable/workable) lead buttons sewn into the bottom corners to hold them down.
"Little House in the Big Woods" mentions how easy it was to melt lead in the chapter "Long Rifle". Laura describes the freshly molded bullets Pa made as "bright and shiny", and until I watched this video I didn't know what she meant, since I knew lead as a dull dark gray metal and thought it glowed some fiery color when it melted the way some other metals do.
@@LordDragox412 I have a decent amount of Native in me...and am American...and how long does someone have to live somewhere to be native? Since no Native is 'native' to America. Heck, some tribes are only 'native to this region' since about 1300...
If you ever cast lead again, try to pour it quite a bit faster than you did here in this video. It solidifies pretty quickly so if you pour too slowly, you get this lumpy appearance, sort of like candle wax.
An electric car can be made once you have access to lead, sulfuric acid (which you might be able to make by bubbling the lead/sulphur fumes through water), insulated copper wire and iron, so if that is the goal, it could be done fairly quickly
@@acr_-kj8gd a battery and a motor, which is what you need for an electric car, the rest can just be wood and iron, you can make lead bearings, grease is one I forgot though.
i dont think he would make a tesla they arent energy efficient its best to burn the fossil fuels once in the engine instead of making power from it then using the power for the tesla
Next time use the p100 7029's not only are they as effective as the 7021's they have an added charcoal filter. They are also a lil' cheaper. I love em'
As a kid we would smelt lead in the chimney to cast small lead soldier figurines. We had molds from the 1870s . Never used any protection because we weren't that smart
12:30 Wait, with this setup and outfit... it really won't be long before "Cooking Crystal Meth from Scratch"! 17:19 Nevermind, looks like they already did!
I live about 40 miles from one of the largest lead mines ever to exist and back in the day, they'd smelt it right there and all the lead dust would fall all over the valley and it's towns and poisoned a ton of people as recently as the 70s. All their tailings also ended up in the river so it's still polluting the water supply and it's still not safe to even handle the dirt in the valley. Legend has it there's still a huge amount of lead in there and someone is looking to reopen the mine. Let's hope with modern methods it'll not pollute the environment
Lead sling shot was super effective. The Romans used a special set of tong like pliers to reach into wound cavities of soldiers who were hit by enemy slingers.
Lol, the end bit was pretty funny. You’ve gotten much better at talking on camera and including your dry humor these days. And your jack of all trades skill has leveled up a lot! Big kudos, dude
That makes no sense, is there something I’m missing because last time I checked H20 and Mercury don’t react, nor does it observe an endothermic process that would spontaneously cause water to freeze.
My great grandfather was a coal miner, after he came to North America in 1900. I believe he did that, when he was still in Eastern Europe. Miners did, and still do a very risky job. A lot of towns in North America, where mines used to be are ghost towns. With lead, it still has it's purposes. It's in the solder, with tin, which holds electronic components on circuit boards. I'd like to see you work with other metals in the future. Cheers!
I grew up around lead paint, lead toys, lead added to gas (which they think increased violent behaviour in the 70's and early 80's), and as late as the early 1990's figurines like those used in Role Playing Games like Dungeons and Dragons and Tabletop Strategy games like Little Wars, Warhammer 40K, and so on, were still all made of cast lead alloys. Growing up when I did it was almost impossible to avoid it.
Andy, I believe you're your own Indiana Jones. You're able to visit a random site and tell what types of materials you can find, how they were used and what is useful to your current goals. I think it's pretty sweet.
You forgot to mention one of the primary uses of lead in more modern times, as a component to electronic solder to prevent the tin whisker effect. Tin in solder builds up very small crystalline "whiskers" that spread out from joints. Eventually, these can touch and short out near by components. It was found that adding lead made this process much slower, although with modern ROHS requirements, leads use in most electronics is fading out. I spent years in a job where I would clean a solder pot in a wave soldering machine. I'd walk out of the area with spots of lead solder splashed on my pants.
I like the contrast between the whole build up of lead safety with the hazmat suit and all and then you just pour motlen lead all over your backyard without giving a shit ...
My dad worked as an oil refinery technician in the 1970's and 80's so he was tested regularly for lead exposure. Once he used some high lead aviation gas to clean off the belly of his airplane and his next lead test showed sky high levels in his system. Don't handle high lead gasoline without PPE.
Puter is a soft safe mental that you can make any thing I’ve made a necklace out of wood first then we used the cut pice to make a mould then I file it out to get rid of the ruff edge it was fun in intermediate.
Would you be breaking the rules if you just went to popular fishing holes and gun ranges to collect lead? I guess it would, but it would be a much easier way to find it. I'm enjoying this series either way.
The toxicity of lead is a little overstated. Burning pure lead can put off some vapors, but the rest of the toxicity stuff is related to food contamination. You really just need to focus on not putting lead into your body to be alright. As far as that goes, smelting lead is actually more dangerous than re-melting lead because smelting lead entails boiling off things like arsenic from the ore, which are much more potent toxins. Something skipped or not mentioned, Lead is also very useful for making glass. Leaded glass takes about half the fuel to make as soda glass and you're less likely to get air bubbles in the end product.
The ground is seeded with lead in many places now because of hundreds of years of hunting. Rarely did they every clean up after themselves. Another good place the gather lead is a gun range where it embedded into everything. Some fishing areas are contaminated with lead sinkers. The problem with lead has long been the indifference that people have shown with where they leave it.
Lead is still used as weights for fishing as well and while it is intended to be manipulated with pliers, most fishermen I know still just bite them shut.
Ayy! You went to Pendarvis in Mineral Point, WI! You should have went to Linden, WI (20min away). Has better lead deposits. Weird to see you in a local (to me) area.
I know with lead, it probably happened a bit by accident. They put this shiny rock too close to a fire, suddenly they can shape it. However, smelting and shaping of other metals is one of the most fascinating Human advances for me. I know it obviously all happened over ages, but just the steps one must take, especially for more complex procedures, the trial and error involved. I mean, for example, imagine that eureka moment to discover the process for hardening steel. All this especially as their understanding of these processes scientifically was advancing slower than the advancements themselves.
I seriously wish I could come help you crafting things. A lot of this stuff would be so much easier with small modifications to the things you make and how you do it.
Actually many pipes in the US are still made of lead and it's estimated that around 3.100 municipal water systems in the US use lead pipes and are at a high risk of lead contamination like what happened in Flint Michigan, which btw still has not been fixed despite being a city over 100k and the risks were actually known when the decision was made to switch the water supply.
11:09 Haha, I love the censorship! But that doesn't look like reproduction, it just looks like Andy talking; is this his way of calling himself a sexy beast?
