Once coal had reached the surface, it was the practice to pass it over screens to sieve it into different grades, ranging from large lumps to dust. In the 19th and early 20th centuries there were three main grades, namely, Coal, Burgy (variations, Borgy and Burgie) and Slack. Material that passed over the first screen, with the largest mesh size, was sold as Coal, also known as Round Coal, Household Coal, &c. This was the best coal and it was the most expensive. Material that passed over the second screen, with the smallest mesh size, was sold as Burgy, which was small coal mainly used to fire furnaces and kilns. This coal was sold at a lower price. Material that passed through the second screen was sold as Slack and this was a mixture of small pieces of coal, coal dust and dirt. This was the cheapest coal and it was typically used to fire boilers for steam raising purposes to drive steam engines. Cotton mills would be the principal consumers of slack.
