Laboratory glassware. Close-up of an assortment of laboratory glassware, filled with a clear, golden solution. A small measuring cylinder and a glass funnel in the top of a buchner flask appear in the foreground. Behind them is a large conical flask. Special-effect lighting is used to emphasise colour and texture and to highlight the tiny bubbles rising through the golden liquid. A calibration scale on the side of a flask appears reversed and distorted through the glass.
