Hey guys - wondering if someone can help me out re. mixing Marks medium recipe.. I have all of my supplies and shadow boxes and lights etc. and I'm just about to mix my medium and then my paints.
I haven't been able to find an answer as to whether I mix the parts by weight or volume however?
I imagine there is a difference between weight and volume for things like Venice Turpentine v/ Mineral Spirits and I really don't want to get this wrong before I start!!
Really appreciate any help you can give!
