Iron Age bronze working

We had such fun at the final public event for the Clachtoll Broch project.

Uist Corrigan (who is now at Edinburgh College of Art) joined me and some local folk and volunteer archaeologists. (That’s Uist keeping an eye on the furnace)

We had the bellows from SSW and built the furnace using local clay, sand and horse dung.

glencanispfurnaceaWe had some local charcoal courtesy of Chris (although most of it came from the Chinese wholesalers in Dundee). Heather Fulton took loads of photos, some of which I’m using here.

We started before dusk and did the final copper smelt of the project.

Just about everyone helped with the bellows, it’s not so easy, but it’s sociable, thanks all who joined in.

We cast the two community bronzes which were lost wax cast.

One of the bronzes was a bear foot print, designed by Bill.

I had spent the previous week preparing the waxes, adding runners and risers and then  dipping them in a clay slurry mix to build up layers of mould which was then finished by enclosing in a cob clay with a pouring funnel.

We kept the furnace going (and the bellow workers) to pour the last bronzes – One closed oil sand 2-part mould, an open sand box with local sand and clay mix; and a closed 2-part mould (although we ran out of bronze in the end)

Most people went up to hear Gordon’s talk, but I’d promised Mandy Haggith that we’d try a copper alloy. So we switched to the hand blower to melt the copper, including from the local smelting, and added some tin grain to get a very local bronze alloy.

The open sand mould was Roz’s bird over waves design; and the closed one Stuart’s panda:-

The next morning I said goodbye to the Art Studio for 2018 and headed back to my studio to finish the final bronzes.

My thanks to everyone for making the Clachtoll broch art project such good fun.

NEOS packing list 1

Just taking some quick pictures before packing my pieces for North East Open Studios (NEOS) which previews next Friday. The work will be displayed at Art in the Buchat. Glenbuchat. Do pop along if you are in the area.

This is a damascus steel bowl on a burr wood stand, it’s so tactile.

Pittenweem Arts Festival 2018

PFA2018i

Pittenweem Arts Festival is on again, do head down to Water Wynd, Venue 70 to see us. (That’s Keny Drew, Nicola Wiltshire, Frazer Reid and I) The net loft looks really good this year with better lighting and the introduction of white fabric to lift the space.

I have a selection of copper, iron and bronze bowls as well as some jewellery.

The allure of copper – Stone to Bowl

copperbowl2018

Alongside the traditional copper casting project I have done a copper/silver cast; using plumber’s copper and silver.

and two-part sand moulds. This is partly sustainable, with all materials being recycled; but the heat used is gas.

copperbowl2018i

One of the pieces sold unfinished at ENOS 2018. The bowl has a metal ‘pebble’ inset, a blue heat patina and is almost clean copper on the exterior because I used a different greensand on the outside.

Some learning – try different sands to give cleaner surfaces but retain textures, cost in the silver, keep experimenting, copper is an attractive metal although challenging to work with.

Iron Casting photos from Studio RoRo

I have some great photos of the Iron Pour that Steve and I supervised at SSW, thanks to Ross Fraser Maclean of Studio RoRo
