The pigments and pens instead of a calligraphy was because I was researching for doing calligraphy and decided I'd do home made period paper and home made period ink, and in researching ink recipes I discovered that there are a number of factors in choosing the right ink for the right paper, so a straight out comparison would be interesting, since I couldn't find such a comparison I decided to do one myself.
