CORK.—The bark of the Quercus Suber, or cork oak, a tree which grows in France, Italy, Spain, and several other countries. It is a very elastic tissue, and is largely used for making corks for stopping the mouths of bottles, jars. etc. The bark is stripped from the tree in square sections, steeped in water, flattened with weights, and dried before fires. For the protection of d chemicals good corks should be used. Those known as velvet corks are the finest quality, an are imported in large quantities from France. Corks should not be placed in bottles containing acids or any substances of a like nature. For these purposes glass stoppered bottles should be used.
To make corks perfectly air-tight they are soaked in melted paraffin-wax.
CORK EXTRACTOR.—An instrument for removing corks from bottles. Fig. 142 will explain its use.
