Art Mail, Rice Paste Adventures

Two days ago I received, via USPS, a small print by Minneapolis painter Mary Klein. She re-interpreted this painting with black ink on a handcut lino block. It's a wonderful little print! I am growing my collection of small artworks. Meanwhile, back in the studio, I am learning that fighting with your rice paste needn't be the norm. I steamed the little lumps for 30 minutes, using John Marshall's recipe. It cooked to a nice PB color, and I felt a sense of EASE working it with the pestle. Considering the last time I made rice paste I injured my wrist pounding it, this was refreshing. Then, I made the mistake of putting it in my studio fridge overnight. The next day I nearly injured my wrist again working it. Where did all the little lumps COME from??? Since my studio is never warmer than 59 degrees in the winter even with the space heater on, the fridge probably was unnecessary. Photo of said "successful" paste before refrigeration.....
