When, by the way, have you last found amber gris outside Wikipedia, Marco? When did you last come across a bit of it on the Dutch sea shores?
Never, right?
* When was the last time you saw a sperm whale near the Dutch coast?
* When was the last time
you personally found resin based fossilized amber ANYWHERE on the globe?
* When was the last time
you personally found gold or silver?
* When was the last time
you personally found Juncus Pygmaeus (Dwergrus in Dutch), a plant species on the red list no. 1 (most endangered) of the Dutch Endangered Species listing?
I did in 1997 on Vlieland!
, I heard later that it had pissed off one of my former Biology teachers at University, as he had visited the same place, but missed it
The fact that we personally don't find something which is known to be rare, does not mean nobody does, nor that experts who actually know where to look, and know how it is supposed to look, will not be able to find it.
Just as another nice example:
* And when was the last time you found a Woolly Mammoth bone on the Dutch coast?
Yet, a fact known by few people, is that the Dutch part of the North Sea has yielded one of the largest and most extensive collections of Mammoth and other Ice Age animal bones. Fishermen almost daily drag something from the bottom in their nets. This is NO joke!
As a consequence, one of the main experts on Woolly Mammoths, Dick Mol, is Dutch!
So never assume something is wrong because you may not have heard of it, even if it requires digging in something as Wikipedia
Another interesting fact: ever noticed all these small pieces of rounded black "wood" lying on the Dutch coast? They almost look like lumps of oil, yet they are thousands of years old. They come from old eroded peat layers, formed in the area where the Woolly Mammoths roamed: the North Sea before it was flooded after the last ice age... I love these historic things!
Two reasons:
- It is far too rare, and thus too expensive.
- There are enough other perfectly fine pigments, so there is no need.
Just as a reminder:
-
Ambergris or grey amber is a knead-able semi solid substance formed in the guts of sperm whales and occasionally beaches on shores. It has NO function in painting, it just, probably mostly historically, had a function in the cosmetics industry.
-
Amber as we "normally" know it (as a gem stone), is fossilized hardened resin from trees. It is NO color pigment (it is transparent as you all know
), and it's only use in painting was as a varnish, mostly replaced by damar and synthetic varnishes today.
-
Umber is a mineral - clay-based - brown color pigment used in oil and other paints. It is valued for its natural transparency, and this is one of the main reasons it is found in many historical oil paintings, to achieve the "luminosity" Mustaffa was writing about.
