Excellent information! I'm a hobbyist coppersmith, so I use tin quite often in my casting. (Will be casting some bronze kitchen knives later this year, and will be afixing agate as knife scales.) My one major feedback is that your audio is very very low compared to most other channels. I had to watch with captions on to understand you.
Cornwall was important pre-Roman but the Romans did not even occupy the area, instead the Romans saw fit to build a wall to keep the Tyne Valley and places like Stanwick, Stanhope, etc. free of invaders. I believe that Cornwall had been essentially turned into an environmental waste land by 600 BCE (trees cut for firewood, arsenic, copper, tin pollution) and mining techniques not able to dewater the mines. Then the tin trade shifted to the Tyne valley and overland (up the Sein and down the Rhone) to Italy (Tuscany) via Vix in France. This route was essentially pioneered by the Etruscans in and Empire that is not recognized. Indeed, by the time of Julius Ceasar (55 BCE) the Etruscan descendants were viewed as Gauls.
Yes historic pollution is a problem in parts of Cornwall, back in the day they just didn't know (or care) how to deal with mining waste in a safe way. Luckily we now have the knowledge and the technology to do that!
Thanks for the feedback and subscription! I will watch out for the audio quality for my next videos, I guess some devices won't play back as clearly as others.
@@ourmetallicearth To let you know, I tried the video on my cell phone and the sound was much better. Congratulations! You video was the first one I have ever watched on my cell phone!
I could hear you okay and I also have a volume knob on my speaker and I can still reach over about.... 1/2 foot and turn it up so I did not have great difficulty hearing you and the graphics are excellent - I just loop the video cause it's way too much info all at once - lots of work in these video's - cut aways - inserting graphics and video clips - and making it all make sense
Great explanations! Thankyou very much . . .
Thanks for good info!

Thank you for your video, here in Far North Queensland ,Australia there's still plenty of tin in the creeks.
Could you please upload at a higher volume? Cant hear. Thank you. Thanks for all the knowledge, learning so much.

Beryllium is not used in the magnetrons since many years on account of its cost and toxicity.
i had to go find some headphones so i could hear you??? love your work

This is a very interesting subject, but I just cannot hear you. Please revamp your sound system. And yes, I subscribed.
