Extra Fine Nib Ink Review: Rohrer & Klingner Sepia
This is review #231 in my series. Here's the YouTube video:
Post-recording notes: This ink was a gift from a generous FP Geek. It started life as "Mystery Ink #50". Check out this FPGeeks thread for more.
Cleaning was quick and easy. I have nothing like this color, so I chose three browns that are as close as I can come. This brown is more neutral and grey than the others. Sometimes, it has strong green undertones. On Tomoe River, from a larger, very wet nib, sheen was easy to see - sort of silvery gold. It's there from this nib as well, but you have to look for it. Note that dry time from that wetter nib was a *lot* longer, so dry time may be exponential for this ink rather than linear...
As part of the exploration of this mystery ink, I did chromatography and water testing (with a different pen).
Zoomed in photo (Quite close.)
Screenshot (Text is a little dark and de-saturated.)
Scan of Completed Review (Very close. Hard to say whether this or the zoom is more accurate.)
Absorbent Paper Close-up (top is puzzle paper like thick newsprint, bottom is old 20lb copy paper) (Both are close. The CP doesn't look splotchy to the naked eye. It's much darker on both papers.)
Line width (One of the lines used for dry time. Magnification is 100x. The grid is 100x100µm. The scale is 330µm, with eleven divisions of 30µm each. The line width for this ink is roughly 300µm. With 231 inks measured, the average line width is 296µm.)
Microscope image (100x. Part that remained in the middle of the slide. Very pale.)
Microscope image (400x. A plant growing from the edge of the cover slip.)
Microscope image (400x. Same as before, but with a cell phone to show color.)
Microscope image (100x. Also cell phone. Another area on the edge of the cover slip. There's a very dark forest green color along with the browns and bright orange.)
