........it's one year ago I see. There was considerable lead in the CRT picture tubes of the old style TVs , 50% is the figure I've heard . Out of interest - crystal glass is also lead addition but likely lower percentage . it can be cut carefully while submerged in water using diamond blade angle grinder.
It never occurred to me to cast sheet-metal. Amazing! I wouldn't have believed it. The cast sheet doesn't look too bad, probably nothing like as uniform and smooth as the rolled sheet. The sand didn't look too burnt, wonder if they can just keep using it? And is it better or worse as roofing? Maybe related videos will tell! Thanks for some startling information. I don't think many people in the US know that lead CAN be welded, and here it's a recognized trade.
@Tony Samson. Soldering (AmE: /ˈsɒdərɪŋ/, BrE: /ˈsoʊldərɪŋ/) is a process in which two or more items are joined together by melting and putting a filler metal (solder) into the joint, the filler metal having a lower melting point than the adjoining metal. Unlike welding, soldering does not involve melting the work pieces.
@@mlummas514 And just to confuse everyone even MORE , consider the term 'brazing' (which is very similar to soldering in that the base metal isn't heated enough to melt it, but the 'filler' is generally a 'brass-like' material rather than a lead based material)
+technosasquatchfilms it isn'tand lead is extremely durabe for roofing, whe're talking about 100+ years durable, where tiles and similar brittle and fall off... it's also the only cost effective radiation shield around nuclear reactors.... (40cm of lead=2m of concrete)
+Côme Thiburs The reactor shielding is unlikely to be exposed to the elements like the roofing sheets. Maybe the lead sheets are stable enough that water and sun dont cause them to deteriorate?
i love lead, and really enjoyed this short video as i have studied metallurgy for a long time
Where are these associated films?
This is really interesting
Hey do you have a idea how to produce xray lead glas/window ? I would be very thankful for some informations.

Nice bit of driving from me there😆

all old lead was cast
@Tony Samson it is welding, not solder.

why do buildings need lead sheets?
+Whoopie I guess I didn't catch that. Also seems like a good way to leach lead into the environment.

lead erosion makes a "skin" like aluminum, or i've been told so.
+Côme Thiburs neat
and the poison ?
They have a respiratory system. Stop crying lul
What about the water run off and lead polution
