Hand-drawn simple laboratory distillation setup on a table, seen from the front, left to right: on the left, a small spirit burner with a blue flame heats one round-bottom glass flask of liquid held up by a clamp stand. The top of the flask neck is tightly closed with one cork stopper, and one thin thermometer pokes down through the cork into the neck. From a side arm on the neck, one straight glass condenser tube slopes downward to the right, wrapped in an outer glass jacket of cool blue water with one small hose at each end. At the lower right end of the condenser, clear drops fall into one conical (Erlenmeyer) flask that holds a little clear collected liquid. Only these things: the burner, the flask with its cork and thermometer, the clamp stand, the sloping condenser and the conical flask. Nothing else in the picture, plenty of empty space above. Coloured pencil and watercolour marker, clean black ink outlines, warm off-white paper, no text.
