Bronze conservation videos

The 2000-year-old lamp of the second video is breathtaking.

 

Really interesting. Thank you for sharing.

 

WOW!!!!!! That second video!!!! AMAZING!!!!

 

BIG question????? So, how do you upload a video that is obviously more than 1 MB???????

 

Oh, I didn't upload these. I just linked the videos from Youtube. The first video is from The National Portrait Gallery by the Smithsonian Institution: https://www.youtube.com/user/NatlPortraitGallery and the second one is from the Getty Museum's channel: https://www.youtube.com/user/gettymuseum

 

Thanks for sharing these. As a sculptor I have had bronzes cast at a foundry and I've cast my own resin bronzes too. I suspect the new patination applied on the first sculpture was liver of sulphur, we put it on resins too, it gives a dark brown finish when warmed up and yes it stinks of sulphur.
I remember reading about some new bright as new penny bronzes, just out of the plaster investments were left on the roof of a large city building, when someone went to find them a few weeks later they saw that they were streaked with different colours, reds, blue, purples etc, apparently residue from all the metals from car exhausts.
