"Egyptian blue — a bright blue crystalline substance — is believed to be the first unnatural pigment in human history. Ancient Egyptians used a rare mineral, cuprorivaite, as inspiration for the color. Cuprorivaite was so rare searching and mining for it was impossible. Instead, using advanced chemistry for the time, Egyptians manufactured the color. It was made by mixing calcium compound (typically calcium carbonate), a copper-containing compound (metal filings or malachite), silica sand and soda or potash as a flux, then heating to between 850-950 C.
“Egyptian blue was widely used in ancient times as a pigment in painting, such as in wall paintings, tombs and mummies’ coffins, and as a ceramic glaze known as Egyptian faience. Its use spread throughout Egypt, Mesopotamia, Greece, and the far reaches of the Roman Empire. It was often used as a substitute for lapis lazuli, an extremely expensive and rare mineral sourced in Afghanistan. After the decline of the Roman Empire, though, Egyptian Blue quickly disappeared from use.”
My BFF says she can’t wear any shade of blue w/o looking utterly dreadful. Purples look great on her, tho.
The wrong shades of olive green drain what little color I have and make me look yellow-y gray. The right olive shades add a normally absent warmth to my skintone.
Had no idea you were a woodworker.
Five years ago, we had a 40ft damson snap out in the allotment after a lightning strike.
I was amazed at the colours in the heartwood.
Reds and Purples and Bronze.
The cuts went to good homes, there are some talented turners and workers around here.
but not screenshots or downloads? i have uploaded photos from my phone, but i have been unable to send anything recently.
i am searching my own settings to be sure it is not on my end.
i am probably, most likely, doing it wrong.
i will have to figure out how to do that.
i am accessing entirely on mobile (android),. it is probably me, though it has never been a problem on Dicourse, before
Just posted some of my most recent projects over on the Creatives thread, made from a maple my wife’s great grandfather planted 125 yeard ago, finally came down a couple years ago. I cut up the good parts snd stashed them in the barn to dry.
You might have the same issue i have on Android (Firefox). The forum here in the posts the upload icon is way way south of the screen. I have to scroll quite a ways to get to it but its there.
