#mudlarking — Public Fediverse posts

So, @stylo_the_unicorn nudged me to post images of the glass bottle shard I found, which to my eyes appears opaque dark blue but when held to the light seems a transparent mid green. There's no direct sun through the thick altocumulus stratiformis opacus clouds (sorry, I collect clouds) so capturing an image was difficult and, interestingly, the camera's colour correction software is processing glass that looks green to my eyes as a redder-browner colour. Any explanation of the apparent colour change in the glass, please?

These gold #cufflinks date from around 1650-1700 and have been protected by the anaerobic mud of the #thames for 350 years, dating back to Charles II

As lots more people arrive today it seems like a good time to chat about a project that I'm privileged to be part of.

I'm delighted to be co-supervising a new collaborative doctoral partnership with colleagues from #QMUL and #MOLA.

Tom Chivers, author of #LondonClay, will be exploring the relationship between people, #history, landscape and environment through the lens of #mudlarking on the Thames!
