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.

I understand the whole notion behind the “If you disrespect your parents, you’re trash.” posts (because a lot of people do it for no reason), but…what about the people like me whose parents abused them? We’re not bad people for not respecting the people who refuse to respect us and instead choose to belittle and demean and hurt us no matter how hard we try to make peace or gain their love/approval. Not everything is black and white. I’m glad you have a healthy enough relationship with your parents that you can feel disgust when you see someone else disrespecting theirs, but please remember that a lot of what you view as “disrespect” is actually just someone sticking up for themselves.

Anonymous whispered: What is 50 shades of grey about? And what's so bad about it?

50 Shades of Grey was originally fanfiction based on the Twilight series, which was then published as a novel (along with 2 subsequent books). It sold over 100 million copies around the world and topped best-seller lists everywhere. It’s about to be adapted into a film, set to come out early next year.

It follows a college student named Ana Steele, who enters a relationship with a man named Christian Grey and is then introduced to a bastardised and abusive parody of BDSM culture.

While the book is paraded as erotica, the relationship between Ana and Christian is far from healthy. The core mantra of the BDSM community is “safe, sane and consensual”, and 50 Shades is anything but. None of the rules of BDSM practices (which are put in place to protect those involved) are actually upheld. Christian is controlling, manipulative, abusive, takes complete advantage of Ana, ignores safe-words, ignores consent, keeps her uneducated about the sexual practices they’re taking part in, and a multitude of other terrible things. Their relationship is completely sickening and unhealthy.

Basically, “the book is a glaring glamorisation of violence against women,” as Amy Bonomi so perfectly put it. 

It’s terrible enough that a book like this has been absorbed by people worldwide. Now, we have a film that is expected to be a huge box-office success, and will likely convince countless more young women that it’s okay not to have any autonomy in a relationship, that a man is allowed to control them entirely. It will also show many young men that women are theirs to play with and dominate, thus contributing to antiquated patriarchal values and rape culture.

REBLOG FOREVER.

Boycott this fucking movie, for the love of god. These kinds of ideas are dangerous and set us back as a society
