Robert Oster Australian Opal Mauve Ink Review & Giveaway!

Robert Oster Australian Opal Mauve Ink: Robert Oster, the Australian ink company with 68 ink colors, and continuing to expand, has created a unique purple ink color in its Australian Opal Mauve. Robert Oster’s Australian Opal Mauve, which is actually a reference to Australia’s opal gem, which are beautiful in and of themselves, is a nice colored ink. Australia Opan Mauve is a dusty muted light purple color with a tinge of pink in a greyish hue. This soft purple/mauve color would be wonderful in letter and journal writing. Although there have been some reports of the ink being on the dryer side and less saturating than some other Robert Oster inks, we found it to be dark and legible, even using a fine tipped glass dip pen.

We found the following traits while reviewing Robert Oster Australian Opal Mauve ink that you may find helpful:

Testing Factors

We used Rhodia Bloc N. 18 paper with a J. Herbin Glass Spiral Dip pen for this review. The dip pen has a fine tip.

Bottle Sizes

All 68 Robert Oster ink bottles have the same, a non-descript 50 ml. dark plastic ink bottle with a distinctive gold Robert Oster Signature ink seal. The best part of the bottle is the white label on top of the lid with the ink color and a small ink swatch reflective of the ink color inside each bottle.


Robert Oster Australian Opal Mauve ink currently retails for $16.00 in the USA. This is a mid range price, not as cheap as some inks, but substantially less than the high end luxury inks on the market today. The 50 ml. bottle is a good sized bottle with the right price making picking up multiple bottles of Robert Oster ink quite easy.

Dry Time

Robert Oster Australian Opal Mauve ink, being a dryer ink with less saturation produces very quick dry time. During our review, with Rhodia paper and the glass dip pen we experienced around a 3 to 5 second dry time.

Bleed Through

Absolutely no bleeding was evidence using Robert Oster Australian Opal Mauve ink. Even during the cotton swab test, we didn’t experience any bleeding with this ink.


During normal use we did not notice any feathering with Robert Oster Australian Opal Mauve ink. However, during the water test, the wettest part distorted the ink lines and feathering was apparent.

Water Test

Robert Oster Australian Opal Mauve ink is not waterproof. During the water test we ran on the ink there was significant feathering and some color distortion. Due to the light color of the ink the distortion was not tremendous and thus the lines were still clearly legible.


Shading is a loved feature with most Robert Oster inks. Robert Oster Australian Opal Mauve ink produces some shading with different tinges of colors depending on the saturation and nib used. Dark purple, to light grey purple with pink mauve tones interlaced within.

Conclusion about the Robert Oster Australian Opal Mauve ink

Overall, Robert Oster Australian Opal Mauve ink is a nice muted purple ink that is sure to please. It has a great dry time, no too bad under water as far as color distortion, is reasonably priced and has some beautiful distinctive colors and tones. This Australian ink is just one of many wonderful and unique colors produced by Robert Oster.

I have yet to try the new Robert Oster brand of inks. The way everyone talks though, it seems like a great ink that is a must try.

This is a rather dusty purple … but some would like it to be more saturated, I imagine.

I’m a big fan of Spearmint!

I’m a real fan of Robert Oster inks, but I find there are basically 2 kinds: nicely saturated with a sheen, and very unsaturated and drier but with very complex color compositions. This is one of the unsaturated but complex colors. I only have a sample, but I love the color. I have found that the trick is to use a larger regular nib (as opposed to a stub) in a very wet-flowing pen. My Jinhao X450 has had great success with R.Oster unsaturated inks!

Don’t have a purple yet. Folks at work are getting used to “unusal” colors from me. Let’s do this.

I’m loving the Robert Oster “Bondi Blue” ink I have -it has such lovely shading evident with a fat nib.

I’ve just received my first Robert Oster ink. I’ve yet to try it, that’s for later this evnening. I’ve got Barossa Grape, so the Australian Opal mauve would be a nice match.
