Thirteen spirit bubbles in case, by A. Lovi, Scottish

Spirit bubbles are sometimes used in the context of scientific research, but historically they have mainly been used in the brewing industry. They are placed into a measure of spirits such as gin, whisky, rum, or brandy to test the alcohol content or proof. For example, the bubbles numbered 22 and 23 are used to test the proof of a double whisky; if it is the correct proof the glass ball sinks to the bottom. The set was made by A Lovi, in Edinburgh, Scotland.
