I was so close to achieving what I had envisaged in my mind! I fell at the last hurdle – my seed heads slumped, cracked and went a funny colour in the final glaze firing! I am not upset about it though as I learned so much on the journey.
After all of my experimentation and investigation into the best type of clay to use, making the seed heads was an absolute pleasure. I enjoyed every minute of sculpting the final pieces and I would very much like to continue working with paper clay, pushing it’s boundaries and seeing exactly what I can and can’t do with it.
It was going so well – I crossed so many hazardous points successfully!
- The drying of the clay over the balloon – popping the balloon at exactly the right moment – if the clay is too wet then it will collapse without the support of the balloon, but if it dries too much then it can crack due to shrinking faster than the balloon. Whilst the balloons weren’t fully inflated and were quite squishy, the pressure inside was still too great to allow for the shrinkage of the clay and the clay would have cracked rather than squeezing and contorting the balloon.
- The complete drying of the clay ready for bisque firing – once the balloon had been popped and removed, it was still likely that the clay was so thin and delicate in places that it would simply tear itself apart as it dried. It did in a couple of places, but that is one of the many benefits of using paper clay – it can be joined even when dry. I was able to patch up any cracks with wet clay as you would with papier mache and it didn’t just crack back off again once dry – the cellulose in the paper pulp created a structural bond that plain clay wouldn’t have.
- Once it was dry it was at it’s most delicate and the slightest knock could have smashed it to smithereens! I wrapped each one in a newspaper nest and wrote signs all over the place begging people to be careful around them and not to touch them!
- The bisque fire – during the bisque fire, the paper content of the clay and the supporting string was burnt away – at this point I was half expecting to find a pile of clay dust in the kiln when it was opened, or for the piecec to be so fragile that they would just crumble when touched, but all the way up until this point they were exactly as I had envisaged – it had all worked perfectly…
Then came the glaze firing.




































Having spoken to Matt and Ingrid, it seems that the problem is likely to be that the glaze I had chosen needed to be fired at 1260 degrees. Whilst crank clay can be fired up to 1300 degrees and the solid crank clay had been fine in my test firings, the fact that the clay was so thin and delicate in some places, combined with the openness of the clay from the burning away of the paper fibres, the clay is likely to have started to liquefy slightly at 1260 degrees. Matt also thought it might be because they were such open structures and may have benefitted from internal supports.
We ruled out over-firing the kiln as my pyrometric cone had bent over perfectly & I had learned a helpful trick along the way – if you can’t see how far over the cone has bent, you can open the vent for a few seconds while you check. This creates a greater contrast inside the kiln, but must only be done for a few seconds. I checked with Matt that this hadn’t affected the firing and he confirmed it wouldn’t have.
I also glazed my test piece that I made from Stoneware and this piece went into another kiln which was due to go up to 1280 degrees. This piece didn’t slump during the firing. This could be due to the different clay, but also it is believed that this kiln didn’t reach the desired temperature of 1280 as the glazes didn’t melt on all the pieces. (my glaze was to be fired at 1260, although it did say it could be fired to between 1240 and 1280 in brackets).

The other issue I have with my final pieces is the colour. My test glazes were the perfect shades to match the stonework at High Glanau, but my final pieces have a verdigris green colour in them. I had to make a second batch of the glazes to have enough to cover all 4 sculptures, and for the darker one I added 4% copper oxide when I should only have added 2%. I also rushed the glazing as it took a lot longer than I anticipated, so I ended up with a camouflage effect rather than the lichen effect I was after.
A lot of people have said that the cracks and the slumping just enhance the decomposition idea, but as a keen plantswoman I know that’s not really how they go. I could perhaps get away with the tears and the cracks and the broken veins as they get brittle as they age, but the slumping just wouldn’t occur in nature – elastic and yielding is the opposite of what they become.
As I say, I can’t be too disappointed – I got a lot further with them than I had expected to. I was told from the start and all the way through the project by various people that I was looking to make something that would be incredibly difficult to achieve, but I persevered anyway and almost got there. I am not giving up just because the Locus project is over and will try again over the summer. Matt suggested trying to make another slightly chunkier one and only firing to 1240 which I will be doing. I also thoroughly enjoyed the process, with the exception of the anxiety of waiting for the kilns to cool to see what resulted inside!
Whilst the final glaze was too green to match the lichen on the stonework, it would not look out of place. The roof and cladding tiles are a similar shade of green and the pieces would not look at all out of place in the context of their intended surroundings. The colour is also a good match for a natural verdigrising of copper, so not out of it’s context within the Arts and Crafts aesthetic.
For my exhibition I went back to High Glanau and took some more photo’s. I had already taken a photograph from the Octagonal Pool at High Glanau, looking up to the terraces with the unadorned pillars and the Manor House in the background. I had this blown up to A1 size and printed on glossy poster paper, however I realised that only the 4 central columns were showing. When I pinned up the poster, I added pencil sketches of the other 4 columns to scale, showing where they all were, as I was concerned that the poster would give the wrong impression – that the 4 columns showing were where the 4 sculptures would go. This wouldn’t have made sense as there would have been no symmetry. The idea is that there would be 8 sculptures – 4 mirroring each other either side of the central path down to the octagonal pool.
I also took a photo of one of the columns with the poppies in full bloom around it so that I could photoshop one of my sculptures in. As the sculptures only came out of the kiln on the morning that the exhibition had to be completed, I didn’t have time to get it printed on the same paper. I also included an A4 print of a photo I took of my glaze test on the steps at High Glanau to show the accuracy of my glaze colour and texture matching to the actual stone (not photoshopped!) Shame my finished glazes didn’t come out like the test!
The 4 sculptures are placed on individual plinths, replicating the columns that they would sit atop. I considered painting them to look like stone, but thought this would detract from the glaze and they would stand out better against a white background. I also included my test piece on a separate larger plinth with my test glaze tiles and my sketchbook.
