Learning To Use Decals


I am not an artist. I do not draw or paint on clay. Nor am I a sculptor. I do not etch or carve on clay. I’ve tried. I intensely dislike what I see from my efforts. You can call it hate. I love what I see in others work when they use any of these techniques with their pottery.
So what is someone like me, who loves the imagery, to do. I love photography and while I am still in beginner mode it does not cause me the frustration trying to draw, paint, carve or sculpt causes. I actually feel as if I’m improving and I like what I see. That is most important. I like it.

I came across some conversations discussing decal work. I initially tried sending off for high-fire color decals and while they worked very nicely it was not the actual look I was hoping to see and it was a bit costly for my particular budget. Fast forward to this year. I keep seeing a name and work I like. Justin Rothshank's
He does wonderful work and has freely shared a huge amount of information about decals with the world of potters. Using the information from his blog I gathered enough tools to start my own series of tests using my own photography.

I am liking what I see so far. I have much testing to do and will share my steps as I go along from what glazes work well at what temperatures to taking a photograph step-by-step from photo to decal.
With the pictures below I’ve noted the clay, glaze, firing temp, speed of firing and what I’ve found with the decal or glaze.

All clay and glaze below is Laguna B-Mix C5 with grog. Glaze is Coyote Clay Shino glaze with Espresso Bean on the rim. Decals were printed on Fired-On Decal transfer paper.
The following picture shows tumblers bisque fired to cone 05, glaze firing done in a Skutt electric kiln to Cone 5 at a fast speed. Decal firing was to cone 04. I was surprised the glaze turned matte since my early tests to these temps did not turn matte and held their Shino colors. I realized this application of glaze was quite a bit thicker since I had to brush this on. As you can see it is rather yellowish and the Espresso Bean rim lost much of it's darkness.

I then took a group of them and decided to fast fire them back to Cone 5 and see if I gained my glaze As you can see by the comparison the one on the left looks like a glaze fired to the right temperature again. I assume the lumps and bumps under the glaze is the grog coming to the surface due to the firings.

 I then decided to try just firing the rest of them back to Cone 1 to see what would happen and they look as if they were fired back to Cone 5. I do lose some of the darkness from the decal but this glaze blends well with the sepia colored decal so I'll keep it. I will need to make sure I have some good strong lines in my decals when using this glaze. I lose the fine details firing higher.
