Ohio Art League
A group of 40 students from the Columbus Art School formed the Columbus Art Students League in 1909 for the purpose of organizing artists for public and mutual benefit. In 1917 the name changed to The League of Columbus Artists and again in 1918 to the Columbus Art League to accommodate expanding membership interest beyond students to include artists in the greater community. The Ohio Art League programs promote and encourage the recognition of highest artistic merit. The League provides opportunities for professional artists to exhibit competitively. Art professionals of international renown have served as jurors for these competitions including Edward Hopper, Max Weber, Grant Wood, Homer St. Gaudens, Philip Pearlstein, Robert Indiana, David Smith, Marsha Tucker, George Sugarman, Klaus Kertess and Audrey Flack.
I've been using Koh-I-Noor Rapidograph Technical Pens since 1969. My aunt bought me my first set when I was 12 and I have used them daily ever since. I love the fact that I can mix my ink colors to match my watercolor or my wardrobe and use "Pelikan Drawing Ink A" almost exclusively. Though the inks made by Koh-I-Noor and Winsor Newton are satisfactory.
If you are a beginner, I would NOT recommend purchasing anything smaller than an 0 (0.35 mm). Even as a professional I find cleaning a 4x0 to be a challenge. I work most often with a 2x0, and find them to produce the smoothest flow, if kept clean.
I used Porcelaine 150 about 14 years ago on some glasses; they have been washed over and over in the dishwasher, and the color is still bright and beautiful. I did bake them in the oven as the directions specified. This is a great product!
