Robert Oster Purple Rock
While we dig up geology jokes, check out the review for Robert Oster Purple Rock.
Robert Oster inks have been a store favorite for quite some time, and Purple Rock is a great example of all the reasons why. The grey violet ink behaved wonderfully and looks great. Oster inks come in a 50ml plastic bottle that is tall and round. The opening can easily accommodate any pens girth, although it can be tricky to fill from when the ink level gets low. This review was done with a Pilot Custom 74 F, Lamy AL-Star B and on Rhodia blank No.18 paper.
Purple Rock has a vintage vibe to it. The ink can sometimes appear grey, although it usually has a purple undertone. It’s a fairly saturated ink and has a similar appearance in a fine and broad nib. The lightest the ink gets is a mauve heather. From there, it briefly touches on some traditional violet tones before heading to a much darker plum that can almost be mistaken for black.
Robert Oster inks behave great, and Purple Rock is no exception. The ink had good flow with no feathering or bleedthrough on Rhodia paper. Dry times were great at 15-25 seconds. While the ink didn’t have any water resistance, clean up was very easy.
I really like cool-toned grey inks, and I would put Purple Rock into that category. It doesn’t read purple right away, but it also isn’t grey. I think that space between colors is so pretty, and that is where Purple Rock lies. You could probably get away using the ink at work, but you’ll definitely enjoy it for whatever writing you do.
As with any ink review, the pen, paper, and person doing the writing will influence the way the ink looks. If you’re not sure about a color, try a sample to see if it’s the one for you.
