The last project of the class was creating a decal transfer. We again used the thicker glue-like medium to mix our enamels with so that the first layer of the transfer would dry before we printed the second layer on top. One of the interesting things about this project was that we used a piece of black construction paper for the background layer of the decal. I took my square of paper and tore it into a rough circle for my background and I really liked the way the hand torn edges came out in the transfer. Off to the left, you can see some project samples we had for inspiration.
We were supposed to use either a hand drawn or computer generated image for the foreground layer. I used an image of what is known as “Buddha eyes” that are often seen on the side of Hindu temples for the foreground image. As in the multi-colored image we created in the last project, we had to concern ourselves with registration of the background and foreground images as we printed. We were to create 4 identical decals, 3 of which would be transferred and sinter fused onto small 3.75″ squares of clear glass. The last decal would be left on the paper so we could use it as a reference point to the fired pieces.
The process we used was identical to the multi-colored image we created in the last project, so I won’t describe all of it in detail again here. In my project, I used a bright yellow enamel for the background on the decal – to simulate the sun – and a medium blue enamel for the foreground image. I was quite surprised by the difference in color after the sinter firing, which you can see in the photo off to the right. The yellow deepened slightly, but the difference in the blue was quite extreme, with the blue looking almost black. In the project sample photo above and to the left, you can see that the color hardly shifted from the reference decal to the sinter fired decal, so I wasn’t expecting such an extreme shift in my final project.
When I spoke with Louise about it, she mentioned that there may have been an interaction between the sulfur in the yellow enamel and the copper in the blue enamel. After seeing the color shift, I understood why Louise had us print four decals and only use three. If I hadn’t kept the one unfired, I would have been guessing about the amount of change I got in my unfired and fired decals.
And so endeth Day 3.
