Last month I mentioned Maryland-based printmaker Amanda Gordon Miller's gelatin monotypes and linked to an article she wrote about her process. I know it was hard to visualize exactly how she uses unflavored gelatin to make a printing surface. Maybe this image will help.
She forms a printing "plate" or block with the gelatin, then applies to the surface inks and hand-cut stencils. (Her article covers all the details, including how she applies her paper.)
The end result is more painterly than a woodcut or linocut.
Amanda earned her MA in Museum Studies from Syracuse University and sells some of her prints through her Etsy shop, Edamame Press.
Jell-o box via Walmart.. Again, clear, unflavored gelatin is used for printmaking, and Amanda covers that in the article, too.
If you prefer to use Jell-o in the kitchen, don't forget that Julia Reed sings the praises of gelatin in her book, Ham Biscuits, Hostess Gowns, and Other Southern Specialties: An Entertaining Life (with Recipes).
