Imagine you are a child living in the late 1800s. Your father works for the local noble family, and sometimes he brings something home which has been thrown out, for your family to use. Some of your favourites are the corks which come from the bottles of fine wine. They are so interesting, and make perfect little boats, or people, or other toys. You sometimes wonder if the children of the family your father works for know what they are missing!
This post arose in a slightly different way to the norm, as I did not specifically set out to show any corks to the children at all. Instead, we were using corks in a craft activity, and the children were fascinated by them. As fewer bottles use corks, children seem to become more intrigued by the lightweight wood, and some children even commented that they had never really seen them, apart from as an occasional craft supply.
Cork is made of the bark which is harvested from a special type of tree – known usually as the cork tree. It is prized as a material for its amazing properties, which include being fire resistant, light, able to seal liquids (it is impermeable) and able to float. In addition, corn has been used for thousands of years. We know that up to 3000 years ago the Egyptians, Chinese, Babylonians and Persians were using cork as part of their fishing tackle. In ancient Rome it was used in a variety of ways, from roofing to the soles of women’s shoes! The ancient Greeks were also well aware of cork and its various uses, and the famous Greek philosopher, Theophastus, even commented on the extraordinary ability the tree had to regrow bark after it had been stripped.
Of course, the best known use for cork, and indeed the use for which most cork has been used throughout history, is as a stopper, used for for sealing liquids and food, particularly wine, in jars and bottles. The Romans and the Greeks both used cork for this purpose, using it to keep food, oil and wine alike fresh and palatable. So effective were some of these corks that a wine amphora sealed in the 1st century BC and found in Ephesus actually still had wine in it when it was discovered 2 millennia later! Yet this knowledge of cork appears to have been lost for a time, with simple wood stoppers used instead, and with less effectiveness, in the medieval period. Then in the 17th century, glass bottles were created and wood could no longer be used. Cork was rediscovered, and has been used to stopper bottles and jars ever since. However, today the use of cork is becoming less common as other methods for sealing jars bottles, such as metal lids and synthetic cork, have become the norm.
