This bottle looks at first sight to be dramatically simple. Yet its looks belie the technical virtuoisty behind its manufacture. There is no other recorded example of "flashed" glass in a cobalt-blue color, although flashed red glass is known (flashing being the technique of applying a thin layer of color beneath transparent glass to give the impression of a monochrome color). On close inspection, the almost regular bubbles are sandwiched between the clear layer and the flashed layer. This can be achieved today by using a compound similar to baking soda sprinkled between the two layers. At a very high temperature, the reaction produces such bubbles.
