Writing on Polymer Clay: Sakura Gelly Roll test

I have a lot of requests for personalized items. That's all well and good when the item or lettering is the right size for embossing, painting, or sculpting letters. However, when it comes to a lot of projects, namely ornaments, cake toppers, and even to signing my own projects when completed, I really needed to find a good pen/marker to do so. Sharpies sucked. I love them for almost everything, but clay is not one of those things, sadly. I used a PrismaColor pigment pen to sign one of the first things I made, but it wore off over time from being on the bottom of an incense burner and being moved around. After a lot of searching, digging through cluttered websites, etc, I found that Sakura Gelly Roll gel pens seemed to get good reviews. I was skeptical, as these are $1.50 or less in most places per pen, and nothing more than the exact same gel pens I used to use obsessively in high school when they were all the rage. I went to Micheal's, and picked up a multipack of metallic Skaura Gelly Roll pens, and when I finished the second curing of a project (a multi-colored fleur de lis for Mardi Gras), I signed the back with the blue gel pen. (While it was still warm, it helps the ink to flow, and to set a little.) After the piece completely cooled, I put it back in the oven a few minutes to fully set it. After it was cooled again, I rubbed the ink, scratched it with a fingernail, and otherwise tried to manually remove or smudge the mark. Nothing. It stayed exactly as it had been written!! I'm psyched, and now totally sold. Sakura Gelly Roll gel pens have made clay life SO much easier! Yay for cheap solutions that work!
