Here's a very unique ink from Noodler's named after the first emperor of China. It's slightly on the acidic side (while most every other Noodler's ink has a neutral pH), and meant to look like terra-cotta (I suppose; it seems too bright for that to me). It also glows under UV, but isn't terribly dramatic. http://imagizer.imageshack.us/v2/xq90/910/QoGL6d.jpg
