The company I'm associated with has some uber-technical testing equipment that they bought as surplus from NASA. I'm not an engineer, so I can't tell you exactly what it is. When I get around to doing the tests (on other makes as well as Bakers) I'll be sure and post the details. I'm very interested in this, as it has direct application to my own artisan case coloring efforts. I've got some pretty screwy ideas about how to manipulate some of the variables in order to recreate patterns. We'll see...

I prefer wood to plastic, leather to nylon, waxed cotton to Gore-Tex, and split bamboo to graphite.
