My glaze dried too dull

[Susan Kuban]

Thanks for your quick reply, Richard. I glazed with sap green, alizarin crimson, and I may have added some burnt or even raw umber. I guess it was the umber that really caused the dullness.

Max Horbund's No. 3 Medium is made by Max Horbund, :-), an artist himself, in New York City. I learned of this product through an artist friend who liked it. The label reads, "Ingredients: A mixture of pure archival drying oils, permanent balsam and other essential oils, beeswax, mastic and dammar crystal." I don't know if that will be helpful to you in understanding what I've put on my canvas.

I've tried a gentle swipe of a corner of the glazed area with a soft rag and mineral spirits. This is not going to work - it removed just a very little pigment, yet the weave of the canvas was exposed.

I think I am going to have to cover that dull area with something, whether it be another, fatter glaze, or a varnish over the whole painting. Is it safe to apply a glaze based on some other oil over what is already there?
