Of all the new Derwent products that I bought recently only the Onyx are not vegan.
I've looked in their chart and all the doubts that I had about 3 of the Aquatone pencils were unnecessary, there are all vegan, apparently, for example ivory black and sap green are just names.
This is were I'll draw my line!
What I mean with this is I'm quite comfortable to buy products from Derwent that are not vegan. Why? Because they've made an effort to present products that are. For example the graphic pencils, the onix, natural graphite, etc are considered not vegan (they don't example why) I'm guessing it has something to do with the way the test the lightfastness with blue wool.
If 60% or more percentage of my artmaterial are vegan I quite happy and I feel that I'm making a difference!
I was feeling overwhelmed and very disappointed with myself when I had doubts with the Aquatone. I said to myself 'Enough with this type of thoughts it's impossible to be 100% vegan be proud that you are already making a difference'.
