29/01/2015 – I have had an epiphany regarding the origins of the word caskil or gaskil – I cannot find any ‘relevant’ location reference to either word nor reference to a surname etc – however examining the letters I now believe the word is Gaskil and I believe this may refer to a ‘shortened’ version of Gas Kiln. This is only a theory and is as yet not backed up or condemned by any known literature!
Gas-fired kilns have great significance to Scotland as they were invented here.
In 1881, James Dunnachie of Glenboig Brickworks, Scotland patented the continuous gas-fired kiln. It consisted of 2 rows of 5 or 6 chambers with transverse barrel arches interconnected with flues. A gas generator at one end of the chambers fed the gas down a central duct and into each chamber in turn. Combustion air heated by the cooling chambers was mixed with the producer gas to give a clean-burning oxidising atmosphere, before being exhausted between the green bricks ahead in the flue. Each chamber was more of a unit than in the Hoffman or Belgian kiln, perhaps giving better temperature control during the burning schedule, but the main advantage was the use of gas which gave a more oxidising atmosphere and more uniform heating. This design was sold to Harbison – Walker of the USA and to many other companies.
Below – A very similar stamp but the start and end of the curved part of the stamp appear to straighten out slightly. This example was found in Canada.
