During breakfast recently my wife handed me her new jar of jam and asked me to open it. Nothing unusual in that it has been part of our married life for over forty years. What was so distressing was that for the first time in our long and glorious partnership I could not open the jar, eventually having to puncture the top with a fork to facilitate the manoeuvre.
I shall be writing to the manufacturer of my wife’s jam in the near future to protest at the new boundaries of tightness they have introduced, but in the meantime it has concentrated my mind on lids in general.
Before plastic and other packaging materials, toothpaste, creams, pastes etc. were sold in earthenware pots. Today the lids of these have become collector’s items. There are basically two kinds of pot lid, the black and white kind and the coloured kind. The black and white ones were first to be made because initially it was only possible to print a design in a single colour.
One of the most well-known pot makers was F & R Pratt. By the 1840s Pratt and a couple more potteries had managed to develop a technique for printing a design of more than one colour and were producing multi-coloured pot lids before the end of the decade.
Whilst initially pot lids carried information such as name of company, address and product, the coloured Pratt lids gradually became works of art in their own right.
Increasing production costs and competition from newly developed packaging materials meant coloured lids were forced out of production by the start of the 20th century. Because of the relative cheapness of the black and white lids they commanded a much larger market and therefore were around for quite a few years longer than their coloured counterparts.
