My Art History teacher had let us know that we were supposed to meet in the project room instead of our usual classroom, which seemed a little odd at first but also filled me with curiosity to see what my teacher had in hand for us. Impressively, it was way more than I expected, being an Art History junkie, the sight of interacting with alabaster, lapis lazuli, ochre and porphyry, which were the mediums used in Pre Historic cave paintings and Ancient Mediterranean art, struck me.
First, I tested the different hardnesses of rocks, alabaster is incredibly smooth and buttery compared to the marble. Both of these rocks can be struck at a side angle, unlike, porphyry which is a rock that is so incredibly hard that one must sculpt it completely perpendicular to the stone. Which is why the Portrait of the Four Tetrarchs is a stunning and jaw dropping piece of art, accomplishing a full sculpture on porphyry must have been of highly praised and talented sculptors.

Then, I moved on to the next station, where our teacher had set up for us a lapis lazuli grinding station. The beautiful blue pigment of lapis lazuli looked stunning on a Sumerian Bull Lyre. They created this pigment by grinding the lapis lazuli with mortar and pestle in order to create a plaster of ground stone, that plaster is the drained several times in order to separate the color from the plaster that keeps the impurities of the actual lapis lazuli stone. Through this process the most percentage of pigment that could and still can be extracted is 10% of lapis lazuli’s actual pigment.The stone originated in a remote Afghan province, the pigment extracted from the lapis lazuli is actually called Ultramarine pigment.

Lastly, and my favorite part of the whole hands-on experience, the ochre paint mixing. Looking at cave findings, have you ever felt the urge to jump on a time machine and see how these people produced these works of art with only the resources of the land? Well I do, and today I felt like I caught a glimpse of how these people felt and what it smelled like as they were mixing the dry pigments with oils in order to create actual liquid paint. Today in class we got to see the different types of pigments mixed with oils to create different colors of paint, texture, and even thickness. I will attach. picture below so you can check them out. Not only did we get to see the pigments, but we mixed ochre with Gum Arabic which had other oils to prevent the molding of the paint and tried it out with water ( In order to dilute the very thick ochre paint) on our own paper.
