Image Transfers

22nd November 2023

I noticed that the plaster had lifted off the wood in places, so I needed to find a way to purchase the plaster to the clay if at all possible. Its not a very environmentally friendly way of doing things as I used PVA only on one piece of wood, PVA and screws slightly raised in another piece of wood, and PVA smaller pieces of wood on the third. Also I was interested to see if the oxidisation effect of the rust coming up through the plaster would work with other materials so I used yellow ochre, iron oxide pigment and zinc filings.

In my head, although I am being very structured, it all feels a little bitty and messy. Whilst waiting for the plaster to go off, I carried on with my idea of image transfer. Using mod podge I had a bit of plaster I didn’t paint so used that to practice the image transfer and also a piece of cotton rag handmade paper, just to see how it would work. I have done image transfer before onto MDF using emulsion so this was a familiar process to me.

I then gradually dampened the top image and started to remove the backing from the paper. It worked reasonably well. I didn’t get brilliant results on the paper, but it worked well with the plaster. Had a ghostly effect.

I had covered the slab of clay in white slip and found some black and white images. They have to be definite black and white images. My image of the train needed to be turned into a negative which I did using adobe software. Its the white areas that the stains adhere to. The image of bits and pieces I found in the recycled paper bin, so for the purpose of experimenting it is what I need.

You mix up stains with water and brush it over the image then dry with a blower, then you press the image down into the wet slip on the object and smooth it over with a rubber kidney before lifting it off.
I practiced with different stains, and had various results. If I got the consistency of the fresh slip on the slap wrong ie, too wet or too thick, it didn’t leave a clear image transfer.
This slab needed to dry and then be bisque fired with the other slab.
In the meantime, the plaster had hardened. the one that was just PVA didn’t stick. Also none of the filings had come up through the plaster, they had stuck to the PVA and I’m wondering if that had stopped the colour from seeping up through the plaster. This is probably when I feel like I’m doing a chemistry degree to understand all the reactions/non-reactions. I have an idea to try woodstains and different paints on these, but I need to come back to this. I still have more techniques to try before deciding on my final pieces.
