Yesterday Neil carried out a watching-brief on the excavation of some trial-pits along side the Morfa Copperworks Laboratory building. A very grandiose building just up the road from where we were digging. During the course of the watching-brief Neil came across a floor surface constructed from copper slag floor tiles, with a depth of 10cm.
A floor surface made out of unusual copper slag tiles.

This is fairly unusual and we’ve never seen it at the Morfa Copperworks before. More usually we see copper slag blocks used as decorative copping blocks on top off stone built walls or as building blocks in more hastily constructed walls. This can be seen in the walls that line the route of the Swansea Canal, where both copper slag copping blocks and specifically squared slag blocks have been used in the fabric of the walls.

What else will the watching-brief turn up? Hopefull more exciting and unusual archaeology will be discovered by Neil.
Our cobbles looking wonderfully clean, after some TLC from our volunteers
Our volunteers have been busy, busy, cleaning the cobbles up so they look extra smart for our report photographs. Then if that wasn’t enough they’ve been recording the drains and the remains of the bridge we uncovered on Saturday.
Johnny, Sophie and Charlotte have been running around taking lots of photographs and making sure that all the indexes and records are up to date. Meanwhile Andy has taken himself of to Birmingham for some well-earned holiday!
