Sunderland
In 1589, salt making started in Sunderland. Large vats, called ‘’panns’’, of seawater were put on coal fires. When the water boiled, the salt was left behind. This is known as salt panning. Today, the road leading to where the pans were is still called Pann's Bank. It is on the river bank near the city centre. As more coal was needed to heat the salt pans, coal mining started in the area. Only poor quality coal was used in salt panning; the best coal was sold and shipped out of the town. This is why the port began to grow. This put Sunderland in competition for the first time with its coal-trading neighbour Newcastle.
