Pigments were created by different things in the old days. Stones, bugs, chemicals were all made to make their various colours for vibrant paintings. Red pigments were created from cinnabar which was highly toxic and used to the make the first of the bright and permanent hues used, and stayed very expensive until the 1300s, when a synthetic version was created. Purple was created with pigmented purple calcium fluorite called antonzonite and lead white to a brighter purple colour. Finally in 12th century, Ultramarine was made from lapis lazuli, bright pigmented that the lazuline blue.
I chose to do pigments from the Gothic and Early Renaissance period because the paints were all so bright and colourful. I would grade myself a 5/10 as I couldn’t do anything on time, and probably didn’t even do this part properly.
