Color on Metal : 50 Artists ...
I just ordered this book, and it's a very interesting book. It's main focus is non-ferrous
metals, but many of the ideas can translate to steel. Using coloring
crayons (pastel-like) and using a fixative opens up a whole new
world of finishes for steel. This is a quality made book and many
people will find it of value if you are in to patination and
finishes on steel that aren't your usual bees wax and turpentine
