An Egyptian painted mummy shroud is undergoing an exciting conservation treatment. Over the next few months, Rita Berg will be discussing various stages along the way. Our last post focused on microscopic examination. Today’s post will address the identification of Egyptian blue using visible-induced luminescence (VIL).
Egyptian blue is one of the earliest known synthetic pigments, first produced around 2500 BC. Its brilliant color is often seen in decorative blue glazes of ancient Egyptian ceramics. The pigment was also used in wall paintings, panel paintings, and textile decoration. The unique luminescent properties of Egyptian blue in the near-infrared spectrum of light can be used to identify even the smallest traces of the pigment in works of art.
This technique is called visible-induced luminescence (VIL) and involves shining a bright LED light onto the surface of an artwork and taking a photograph using a camera that has had its filters altered to be sensitive to the near-infrared region of light waves (approximately 910 nanometers). To the naked eye, the artwork appears normal, but the specially filtered camera captures the intensely bright emission produced by Egyptian blue in the near-infrared region.

finding out someone’s been talking shit about u
watch ur fkn back!!!
I just want this on my blog for all time.
Like seriously, why isn’t pole dancing an olympic sport? This is freakin gymnastics. This is strength and skill. This is not sexual whatsoever. Why does pole dancing have to be so stigmatised as a sexual thing that only strippers do? I have great respect for all people who can pull this off. This is art and beauty right here.
HEY FUN FACT: pole dancing is known as something strippers do because strippers invented it. And that’s okay! It’s okay to have respect for strippers and the hard work they put into what they do! Let’s stop trying to take the stripper part out of pole dancing so upperclass white girls can do it without being ~stigmatized~ because god forbid women be sexual.
because life is fucking hilarious sometimes
I’ll just leave this here and let you think about things.
Don’t fuck with Sam Winchester or you’ll burn
this might go over the heads of some of the kids on here.

This is the greatest post I have ever seen because it is both a pun and a harsh truth.
I showed this to my 11 year old brother and asked him if he knew what it was. He looked at it for a few seconds and said
"I dunno. a printer?"
won’t drink lukewarm water but i’ll put another person’s genitals in my mouth
who the fuck drinks lukewarm water?
