Kevin at the JustWrite Pen Company has very kindly sent me 4 more inks to test. So what can they do?

Blackstone Black – this is a thicker ink than the Stump. Doesn’t blend that easily with water, washing out in gradations of greys. No hidden hues. A limited reaction with bleach, turning gold in some of the less concentrated areas. Easy to write with, flows well.

Blackstone Blue – this is like an in between of the Harbour and Reef blues. Mixes with water easily, washing out gradations of blue with hints of turquoise. Reacts well with bleach turning a white gold. Easy to write with, flows very well.

Blackstone Yellow 8.1 – this is a thick uneven ink. Doesn’t blend that easily with water, washing out in gradations of the yellow. No hidden hues. A very limited reaction with bleach, turning pale gold in some of the less concentrated areas. Great colour to write with. Similar in a way to Apache Yellow.

Blackstone Yellow 7 – a lighter and more even colour than the 8.1. Mixes with water easily, washing out gradations of yellow. A limited reaction with bleach turning a pale white gold. Very easy to write with, flows well.

Below is a writing test for the Blackstone Range.
