glass patchwork

I’m making a series of windows of which large sections are made out of glass pieces from my scrapbox, patchwork style. I’ve done this lots of times before, but that doesn’t stop the scrap box growing in size, with pieces dating back to the 1980s when I first started painting and firing glass. In my endeavours I’m inspired both by fabric patchwork, which I used to spend a lot of time doing, and by the fragment windows that you see in churches.

Sorting the pieces, mainly by colour.

Sorting my glass pieces comes easily as I know them so well. I’m ordering them by colour because the pieces are nearly all by me and the subject matter and style is pretty consistent over the forty year period that they cover. Many of them are samples from commissions that I did or didn’t get or from pieces that went wrong. I can often remember what I was listening to on the radio at the time I was making the sample - like a proper patchwork quilt all of my life is in these pieces.

The pink section cut and numbered, the yellow section cut and numbered.

I reached number 121, then made a list to see if I really knew where all the pieces came from. Lots of them are useful colour strips which I can’t date, for example numbers 21, 23, 24, 27, 29, 60 and 61 below. Above you can see sample pieces for the last public commission I installed in Liverpool Hospital almost two years ago (numbers 31 & 33 on the right) next to a piece from a dismantled 1987 panel (no. 34) and some Bournemouth pine cones from a residency I did there in 1995 (36 and 38).

The four corners all together (but not as they will be in the windows).

I’ve planned the next stage of the windows around all of these fragments. There will be black and white painted/sandblasted sections that pick up on the marks, patterns and shapes contained in them. I’ve drawn everything up full size (see window A below) as I can’t afford to have second thoughts once I start on the glass - but with apologies to my clients for the extra time that all of this takes.

Order And Chaos

Towards Order 740 x 740 mm

I made the big, square panel above recently. It combines one of my melted pieces of slab glass with a lovely piece of old window glass. The small bubbles and wobbles in the large clear section don’t show up in the photo, likewise many of the textures in the coloured glass surrounding it. Handling a big glass panel with the hole I had cut in it was tricky, so was inserting the central piece of glass (with a lead wrapped around it) into the hole. The front is very neat, so is the back but it is copper foiled.

The design followed on from the shapes of the glass scraps I chose for the border, with colours getting darker towards the edges and harmonising rather than jarring with each other. At one stage, I was going to paint in a loose style over these border pieces, but then my desire for order got the upper hand and I made a plan (below) that returned the composition to a geometric framework, with straight lines and right angles.

The painting and sandblasting plan.

As I planned the painting stage, I tested each type of glass I had used in the composition by firing it in the kiln with splashes of enamel, oxide and silver stain. The pieces looked great all together, so I spent a happy evening leading the sample pieces together (below) in a panel that returns the glass scraps to a jumble of chaos.

An Insertion

My 1978 diary records me learning how to cut a hole in a piece of glass - ‘an insertion’. Because I have a tendency to keep everything, I found the 1978 insertion in my glass racks (above) and was surprised to find how close to the edges of the background glass I got as I smashed and nibbled my way to the perimeter of the circle.

These days, I use a drill or order a piece of glass already drilled with holes. I have been known to sandblast through the glass to start a hole off, but decided to return to the old school method to cut a big hole for a chunky glass insertion with an irregular shape. The method goes like this - first score and open up two circuits; then cover the centre with crisscrossed lines; then start bashing from underneath the glass; then start removing squares of glass with the notches of an old fashioned glass cutter; finally remove the edge pieces with glass pliers.

Handling glass and finding out how much it is willing to do for you is satisfying. It was actually harder cutting small holes in thin glass to make the central panels of glass sketches that explored some ideas. Should the colour of the glass extend beyond the circular lead line (above right) or be contained by a thick lead line (below right) ? Should I combine black painting with enamels on the coloured glass strips (below) or should I introduce sandblasting in lines that ignore the leading (above) ? It’s hard to decide these things on paper, but the little glass sketch often provides the answer.

Tree patterns

Combination Trees 350 x 350 mm.

As you can probably tell, I made the panel above by leading together glass pieces from two different styles of work, both based on trees. I happened to have the two painted pieces of glass shown below in a pile on my work bench and had a feeling they would go together well. The finished panel also uses other pieces of glass from the same two series as I fitted the two patterns together in the best and most treelike way.

The coloured tree pattern is one I invented to show a woodland scene (I don’t think I stole it from anywhere) for a commission that I never got a great photo of, the one above was taken in my studio window before installing it. I then made a series of panels that were deliberately a cross between a design and a colour sample (below). Three years later I made the black and white trees pieces as samples for a front door commission where I tried out different blacks and greys as well as different methods for making the foliage patterns.

With my leftover pieces I made a second and opposite combination panel (below) where the coloured pieces float across the black and white sample like patches of light in a woodland scene. I’m able to chop these pieces up into complex shapes and then lead them together because it is the right type of glass - i.e. 2 to 4 mm thick whereas most of my work from the past thirty or so years has been made of glass at least 6mm thick and often toughened or laminated, as are many of my samples. These are not commissioned pieces and it’s a wonderful novelty for me not to have to get a beautifully drawn design agreed by a client before starting the making stage. The downside of this spontaneous way of working is that I don’t see mistakes (in the design) until the glass is cut, leaded and soldered so I have to pull the panel apart and change things, aiming for the sort of perfection that happens very occasionally.

Scrap Glass

For a recent commission I had to make a lot of colour samples using transparent glass enamel mixed with a drop of lavender oil and another of gum arabic in the traditional way. With the leftover paint I coated rectangles of glass with two colours against each other and once fired, saved them in a box. The next stage, cutting them up then leading them together to make something satisfactory, proved harder than I thought.

Scraps cut up and arranged to make scrap panels 1, 2 and 3.

My first idea was to make exuberant curved shapes with background pieces cut on the slant (scrap panel 1 above and below). The offcuts from the slanted pieces made an effortless triangle panel (scrap panel 2 above & below). I shouldn’t have been surprised that panel no 2 was so much better than panel no 1, as I wasn’t trying too hard - always a recipe for disaster. There was too much yellow in no 1, so panel no 3 (above right) was an attempt to deal with the yellow by making it the spine of the piece and using the colours in a more ordered way.

Scrap panels completed, top panels 1 & 2. Bottom panels 3 & 4.

The original format of panel no 3 looked very clumsy, so I cut it down to make a smaller panel no 3 (above right). Finally, to emphasise the original idea of the two enamel colours coming together on one piece, like a simple flag or landscape design, I made panel panel no 4 (above left) where the bands of complimentary colours frame other painted and sandblasted scraps from one of my many boxes of broken glass and sample pieces.
