Stone to Bowl grand finale

Last week was my final week of work at Scottish Sculpture Workshop on my VACMA funded Stone to Bowl copper project.

It focused on getting the bellows organised so that I can work anywhere in the landscape. Monday was spent fixing the blower which had arrived fractured. Eden Jolly did most of the work as it involved tig welding, but I did the cleaning of the joins and offered cups of tea. Eden and Fleur (an Erasmus student) made it a super wee base and I went to Portsoy to get it some flexible tubing. fanblowerSept18By Wednesday all was ready to return to copper smelting trials. The smelt balls tend to over heat in the shaft furnace as it’s hard to see what is going on.

So on Thursday I dug a pit furnace and trialed that smelting with great success.I got 35gm copper from 50gm ore in 30 minutes and using about 2kg of charcoal.

On Friday it was time to trial the bowls mentioned in the project title. This was using ore I’d smelted alloyed with 10% silver. The photo shows the open mould after casting. The copper did not complete the pour. I need to redesign the bowls with a thicker base. Even after heating the moulds and with sling casting, the copper would not stay molten in such a thin walled vessel.

Spending 4 weeks developing processes and tools has been brilliant and the work goes on.

Stone to Bowl

Finally the hand cranked forge blower has arrived. This is hopefully the last piece of the Stone to Bowl project. The forge blower will deliver air to the furnace, powered by hand rather than electricity. I’ll find out next month at SSW if it can be made to work. If the bellows can be hand powered it means that I can work anywhere,

This is the model we hope to replicate.

Some of the copper that I smelted at the Sculpture workshop was not very pure. By hammering it I was able to get rid of much of the impurities ready to alloy with silver and melt for casting. I think that this was the first time that I used this blacksmiths hammer and my rather rusty anvil/

The New Year bonfire was the first trial smelt of the year. I didn’t expect much from it and it wasn’t a great success, because the bonfire dropped through into the rock pool beneath it. It seemed a good way to celebrate the New Year though.

The photo is the wet remains when the bonfire had burnt out, a gift to the sea.

 

Cambo stables exhibition

Still time to drop into the new visitor heritage centre at Cambo and see some artworks. Some local artists, including Keny Drew, Judith Heald and Linda Jackson, have a horse stall each to display their work. This is mine.

It’s a lovely display area and there are interesting displays about the history of the estate and the stables.

Most days you will find the cafe and shop open as well.

also your eyes may focus better than my photos…

They reopen 4th January 2018.

Workshop in Munich

I did a wonderful workshop at Peter Bauhuis’s workshop. A different casting technique (lost wax), an opportunity to work with different alloys and forms and a generous and expert teacher. This finger ring is in 800 silver and emerges from casting with this great surface patina and texture.

These little bowls are shibuishi, copper and argentium; in a style influenced by Peter’s work. This is the first time that I have cast argentium. I also now know the secret of successful copper casting.

This copper ring, made from a twist of wax wire dipped, came out of the casting process with this lovely patina and texture. It already has a new owner.

 

 

Alchimia, into week 2

I continued with the resin and the foam. I had some disasters (too much hardener):-

and too little hardener (parts are sort of bendy):-

and some more door designs

The foam is melted away with acetone, leaving interesting ‘insides’ – the courtyards and corridors that are behind the street doors:-

Some texture work to capture the aged walls and surfaces:
