At the cold end of the Lehr (or annealing oven), the glass emerged into a room known as the Shrower. Here the glass was inspected by women for any faults and then sent to other departments around the site for decorating, finishing and packing. Any damaged pieces were rejected , broken up and recycled as cullett.
It was not unusual for young children to be crawling underneath the mechanism to keep the chains working beneath.
During the first half of the 19th century, glass was taxed by weight and an excise officer or taxman was stationed in a booth to supervise the weighing of glass as it came out the Lehr. The Shrower was kept under strict lock and key so that no goods could be removed before they had been weighed.
The manufacturers bitterly resented the presence of these Taxmen and they became known as 'Watchdog's' sitting in the 'Doghole'. The managers had to give written notice of virtually every operation of the factory and if the Taxman could not attend straight away the whole production process had to be delayed.
