I had intended to have some new ones done this week, but the workshop occupied too much of my time. Preparation and etc....
I have no mordant but have used it in experiments at EK. The dyes I have used, can be "self mordanted" due to their high molecular weight. At the present time, I am just imbibing them into the coatings. It works as a quick test.
I lack a cyan dye though. None of the ones I can get are azo dyes. They are anthroquinones which are not suitable. I prefer using a metal mordant such as Aluminum or the like.
