SUMMARY:06/20/25 Intro to Oil with William Noonan
DESCRIPTION:Friday \nJune 20th \n6:30-8:30pm \n$40 without materials \n$60 with all materials supplied \n$40\, $60 to include materials in your registration \n  \nFor absolute beginners or oil painters who need a refresher and some renewed courage. \nTopics covered will include: materials\, pigments\, brushes\, solvents\, basic color mixing\, paint application\, how to start a painting. All the basic principles of oil painting with hands on practice. \nMaterials can be supplied * if you purchase the ‘+ materials’ and includes everything you need for the class including canvas; everyone else is expected to have all the materials on the materials list. \n*NOTE: supplied materials will be water mixable oils\, not the traditional solvent based process. \n  \nMaterials List:\nOil Painting Set up for beginners. Student grade paints are good for getting started\, you don’t need expensive artist grade paints. \nYELLOWS:\n1 Cadmium or Hansa Yellow Light\n1 Cadmium or Hansa yellow medium \nREDS & ORANGE:\n1 alizarin crimson or magenta or quinacridone magenta (purplish red)\n1 cadmium red medium (true red)\n1 Cadmium Orange \nBLUES:\n1 Ultramarine Blue\n1 Cerulean or Viridian \nEARTH TONES:\n1 Burnt or Raw Umber\n1 Yellow Ochre \nWHITE:\n1 Titanium White \nBRUSHES… China bristle filberts are the best. You will need to start out with a good range. Start with at least one filbert of each of these sizes #2\,3\,4\,5. Avoid synthetic bristles- they don’t stand up to the rigors of oil painting.\nSOLVENT… Gamsol or some other brand odorless mineral spirit. This is for traditional oils not water mixable oils.\nPALETTE… disposable paper palettes are fine to start out with.\nPALETTE KNIFE… the kind that has a bend in the handle and is shaped like a pointy trowel.\nCANVAS…For beginners it’s best to have a few canvas boards to start out with around 11×14. \nPAPER TOWELS ….. don’t forget these! They are invaluable.\n  \nREFUND AND CANCELLATION POLICY
