Tools of Techno-Textures that I used for rubbings and stampings are pictured below:
buttons from a fax machine, the casing for Apple earbuds.
some kind of wooden embellishment purchased from a craft store
fax machine cover (one of my favorite mark-making tools)
Char-kole, white pastel, watercolor crayons, acrylic Quinacridone Nickel/Azo Gold
rust dust (formerly rust soup made to soak metal items in so that they catch the rust and get started on their rusting process, but then all of the soupy evaporated, leaving dust and a very cool pattern--it's a mystery to me.
I also used matte medium for collaging and for sealing some parts of the work.
