cobalt blue colors variations
by r Cowper
Peter, On reading some of your commentaries on the coloration of ming vases and general ware I wondered if it is right to assume that all the vase decoration shown on an item should all be of the same colour intensity ie the same depth of colour and not two separate colours of light and dark blue? I asl this because the other day I saw a vase for sale where the colours differed. Although the foliation was uniform deep blue all over the vase the decorative circles and triangles at the middle and the base were of a much lighter colour. I own a ming vase which has distinct colours but each color used has the same depth and quality as if it wre adorned with each colour from the same batch of paint when it was fired, but the one I saw the other looks as if the drawer stopped and went away to get a new lighter color blue for the different floraslc decoration at the middle and the base. Ihave tried in my own naieve way to use some of your thinkings on deliberate forgeries and wondered if I were heading in the right direction to reason that the vase I saw made me suspicious and besides this the vase I saw looked just to good and new, surely over the passage of time all colors take on a worn desicated look after all these things are supposed to be centuries old?
