Some notes on what there is to find at and around the furnace site. Photos to follow:

Immediately upstream of the bay are the remains of a 19th century bridge which appears on OS plans. There are four lengths of bullhead mainline rail, and brick retaining walls, much degraded. There is a scattering of these "modern" bricks in the stream through and below the bay. I have not seen anything that could be considered older in terms of bricks.

Looking east across the furnace site below the bay. The light patch is just east of the stream, the depression closer to the camera is low enough to be boggy and effectively at stream level. In the stream close to the light patch is where the magnetic waste is found.

The bay has two gaps in it, one carrying the current stream, and has done so at least since the first large scale OS plan around 1870, and this dry channel, to the west, which leads to a point where it divides, one branch going directly back to the stream, and the other running parallel northwards through and next to the large cinder bank.

Since first posting about this site, I have now found out that it was a double furnace, as it did cast guns, up to culverin size. Single furnaces did not have the capacity to produce enough melt to make a cannon in one go.

Looking at this link, you would need to cast about two tons of iron to make a field culverin. Now to find a video of one being fired!
