This observation of heaping gloy may be related to temperature. I keep
the heat down in my studio except when I'm actually out there working,
and I worked with the gloy right away when I went out there today,
before the room had warmed up. It may be that the gloy, like dishwashing
detergent and some other fluids, grows thick and sluggish when cold.
But gum never does that.
