This cool slide by Dave Colton features a bright orange, purple, green, white, black, and steel wool spiral section on one side, a matching incalmo circular pattern on the opposite side, a black horn that works as a handle, and a black knob on the incalmo section. The push is large and well shaped, and the hole is medium sized. All black glass on this slide appears black in normal light and translucent purple in bright sunlight. The bowl measures 5" tall, 3" wide, and 1.75" deep, and it comes on an 18mm joint.
