My question is dealing with fading of charcoal. It is a proven fact that woodburning fades in UV light. That is because the wood is burned into charcoal. A hunk of cooking charcoal, like Kingsford, left in the sun bleaches with the UV light. One artist in our figuring drawing class makes his own charcoal sticks by burning grape vines inside a metal pipe. I’m guessing that his home-made charcoal will also fade the same as a hunk of Kingsford charcoal. My question, is the process of making artist charcoal different? I’m guessing the colored charcoal uses color fast pigment that is fade resistant, but how about the black? Maybe the only way to test is to test natural black charcoal next to artist black charcoal on the same surface and put it in the sun?
Thank you,
Well,
In fact everything fades in UV light.
There is no material that doesn't even if they say so. Do not believe it. Sooner or later will fade.
