Large Scale Enameling

Another student from the Glasgow School of Art came to see if I could help with the enamelling of large copper pipe for her MFA show.  Mimi shows the wide appeal of the GSA as she is French Canadian - although I thought her a French national for several weeks.

This required a lot of experimentation. The electric kilns oxidised very badly if placed in a cold kiln and taken up to temperature.  The glass kiln worked much better with this kind of heating.  However, it is known that copper enamelling is done by placing the copper in the annealing oven when it is hot for a few minutes.

Among the first experiments were getting the enamel powder around the whole of the pipe.  Normally, enamelling is done on a flat surface, and the powder needs to only sit on top of the copper.  With a three dimensional surface, a flux needed to be applied, which would be viscous enough to stay on the pipe without dripping and also hold the powdered enamels.

So be began experimenting with temperatures required.  It became apparent that there was so much heat lost in opening a large kiln that we needed to heat the kiln 50 to 100 degrees above the 800 target temperature. This depended on the size of the kiln, but not in the way expected.  The smaller kiln lost more heat and required more time to recover than the large kiln.  So the large kiln needed only about 50C over the target temperature, and it recovered to 800C within 5 minutes which was enough to heat the pipe and fuse the enamel to it.

This heating process was very dramatic as you can see from the photos of the process:

Even though I was standing 4 metres away, I could feel the heat almost instantly.  But denim jackets put on backwards, gloves, heat reflecting sleeves and face guards were sufficient for the brief exposure to the intense heat.  

Then once the kiln climbed back to temperature, they had to reach in and take the cured pipe out without letting it touch the floor of the kiln, or burning the surface on which the pipes were cooled.

The enamelled pipes were of course only part of Mimi's  MFA exhibition.   All the MFA students exhibit in an old glue factory!  The most interesting part of the building for me was the tanks which were still in the building.   Other wise it was a series of rooms and large (probably) drying areas.

The whole MFA show was varied - from a number of video pieces and installations, installation pieces some of which had a craft appearance, photography, but surprisingly (to me, but not others who follow the conceptual art movement) very little painting.

It is good to report that Mimi received her degree and is now off to mount an exhibition in Germany, before getting ready for others in the UK.

Glass and Knitted Wire

After Glasgow International I found myself involved in a number of projects relating to degree and end of year shows.  My interest in these has led me to neglect blogging.  I am out to make amends now.

A student from Shetland College got in contact - upon a recommendation from Cheryl Jamieson - to arrange a few days in the studio to investigate the incorporation of wire knitted in Shetland into glass fired in Glasgow.  This might be the most far travelled set of pieces for an end of year show - this year at least.

We started the week off with a visit to The Dhabba, an Indian restaurant near to where she was staying.  Discussion with the owner revealed that his mother came from the same village in India as the student stayed with with her former husband. Lots and lots of gossip was traded in between mouthfuls of  good food.  It was one of the most enjoyable evenings in an Indian restaurant I have ever had.

The next day work started with lots of tests.

Translating work into a new medium is time consuming.  It turned out that she was relieved to be able to get a rest at last when five pm came around.

After three days of intensive work, I allowed a day off for shopping ( and a visit with her sister).

The piece I liked best was this one:

I think it is because it resembles a knitted sweater.  The folds in the glass are due to the kiln posts interfering with the glass as it slumped down from the supports to the underlying glass and knitted wire.  This was done to avoid the excessive bubbles some of the other pieces had even when supported at the corners with pieces of glass to let the air out during the bubble squeeze.

Other pieces of her work can be seen in the Shetland College end of year show.
