After listening to the recorded lecture from 9/13, please read in your textbook and watch the clip above on youtube to determine how the Greeks decorated their vases. Specifically, what I want you to do is write a few sentences explaining this process in your own words. I will ask you at least one question about this process on the exam.
To give you a hint, consider how the vases go from an initial state of almost being solid red to the finished product of a contrast of red-black, figure-ground, or vice a versa
