During Prayer, Bistre Ink

[Claudemir Bonfim]

Hi Allan,

As far as I'm concerned he used bistre and sepia mixed up. I read once that it looses its quality over time. Rembrandt made lots of experiments and he always mixed pigments. But if you say it is pure bistre, I'll believe you.
I've seen some very old stuff in bistre including maps and portraits, it's like Van Gogh's work which has lost some of its colors, but is beautiful.
Now I cannot recall whether the material I read about it was talking about its permanency on paper, fabric or whatever.
I'm sorry if I made a big mistake here.

And Beth, you should look for restorer's suppliers. Artists suppliers are usually concerned about the latest materials.

Bonfim that was the beauty of the Bistre, it does last but it fades to a lustre as it ages, I am sure someone has made them even more durable by now.

Restoration places is a good idea, but I'll keep my fingers crossed for your Holland buddy!

I'll post here ASAP.

Thanks again Bonfim.

Whew... research today:

I spoke with Robert at Kremer Pigments, Inc.

Their Bistre and Sepia ink does have a shellac base

He did say he just made a batch of Iron Gall ink which he is going to bottle and sell. I am not familar with this this and just wonder if it's a darker/blacker ink than the Bistre. It does not have a shellac base.

If you are interested:

Hi Beth,

All I got from my friend is a bistre used to paint on metal. It costs about U$ 20.00 for 60 ml + shipping, so I think it is not the same one you're looking for.
