I did do a little restoration work while I was there for the painting department. This was on panels from a window by Johann Klaus in the
First I will explore the work I did in the glazing department starting with the two projects featuring lamination, Vladimir Oldenburgs retirement home and Guy Kempeas toilets.
The German way of making up a window uses paper templates which are cut for each and every individual pieces of glass in the window. The glass is then cut to the templates. This is instead of having everything cut to a design on a big piece of paper which is obviously how it is done in the
(Fig. 24 Paper template over glass showing sawing technique.)
The first job I was given at Derix was to cut glass sections to the templates given using a Taurus Ring Saw by Gemini made in the
My first step in this process was to lay the template out on top of the glass and when I had it in the correct position hold the paper down with weights. I then drew around the rectangular shape with a water resistant pen. I cut out this shape on the saw a couple of millimetres from the pen line then ground the rest down on a glass grinding machine. The only difficulties were that the pen lines kept washing off, the large glass sheets were difficult to balance and if the paper got damp it would lose its shape. On the whole though it was very straight forward. It took me a few days but I did about twenty of them all together and I was happy with the results.
On both the Oldenberg project and the Kempea project I got to see and take part in the lamination process which was the same for both. First the glass is cleaned thoroughly with white spirit. The larger piece of glass that is to be glued onto is put on the table.

Vinyl covered the areas of this sheet of glass that are not to be glued. Tape is put around all four edges of the glass with a couple of inches sticking up above the surface of the glass, this creates a barrier where excess glue cannot pass and stick the glass to the table accidentally. Strips of sticky thick foam which come in a roll like tape are stuck down creating a damn around the area to be glues to stop glue going further than intended. Squares of this foam are also stuck at the edges of where the new piece of glass to be laminated will go, and at the corners so it will be easy to get everything in the right place. This also stops the glass from sliding about and moving once stuck down. The upper surface of the glass, the side that will not be laminated, on the piece getting stuck down is also covered in vinyl.
