If you've been following us on Facebook, you've seen the pictures of some lovely paleolithic cave art. That green pigment was really strange, and Joseph's curatorial assistant ran some tests to have the composition of the pigments broken down. The yellows, reds and blacks were the 'usual suspects'- clays, burned shells and so on. But the green- now thats the odd one!
As it turns out, the green pigment is not that easy to explain. A friend of the museum, Dr Greenman was able to do some more in depth analysis. The pigment is the...ahem...by product of algal blooms fed in frigid waters with high levels of...well, lets just say the waters must be down stream of where birds nest in droves!
The pictures are all up on the main Facebook page, so you should go take a look! The photo of all of them grouped together to complete the picture was taken, but that file is corrupt. Sadly, the camera also seems to have malfunctioned- it looks like the mirror is cracked. When we used photoshop to put the images together, the dang program kept crashing. So, you all are out of luck. No complete picture for you. Guess you'll just have to come on down!
