Let's tackle another new release, Robert Oster Aussie Gold. I purchased my sample of ink from Anderson Pens.
Aussie Gold is a dark yellow, it reminds me of 70's yellow.
In large swabs there is some shading, and it turns almost black when super concentrated.
Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.
Dry time: 50 seconds
Water resistance: Low
Show through: Medium
On Staples 24 lb copy paper there was a little bit of feathering, but not bad, and no bleeding.
I used a medium Pelikan M605 White Transparent on Tomoe River paper. The ink had an average flow.
Overall, it really reminds me of 70's yellow. It's pretty well behaved, but the dry time is on the longer side at 50 seconds. The color is very close to Robert Oster Green Olive, so you probably don't need both.
