Wow that's a lot of effort, and super interesting and useful! Lots of great information here, including the advisory about the gloves. And the comment about the microphone... 😅 Thank you!

@4:46 Cu is added to steels to improve machinability (lowers work hardening rate). Makes sense for mass produced inexpensive screws. @12:30 I don't know why they use those elements but Hf pretty much always comes along with Zr. Great video!

God, this is so cool and soo through!!!

Even less lead than we were led to believe.

So if it is dishwasher safe would it be possible to dissolve that lead through the plug, or is it pretty stable, especially under that cap you had to pry off? Nice video, very informative. Keep up the good work.

That is not my area of expertise. It appears the lead (Pb) is in some sort of polymer matrix. It's unlikely washing in the dishwasher would lead to lead contamination since soap and water typically removes lead from surfaces. We can't say for sure if the lead will leach out without testing. If you hand wash you shouldn't have any issues.

Do you know which brand is the window from ？
