remove it. I only had this color ready for use and didn't want to wait for my
reddish clay to soften enough to use instead. I didn't think of adding water to
the red clay soon enough that it was ready when I got to this stage. I tried adding green food coloring to the clay but it didn't show up. I know I could use iron oxide or some other oxide, but I don't want to make a permanent change to the partition wall clay. I'd like it to stay as close to its original makeup as possible so that there are minimal surprises if I ever re-purpose it and kiln fire it.
