I'm not a pro at painting and firing tile, but I do dabble and have some fun once in a while so here is a bit of my dabble.
In this case I just started with a normal 6 x 6 clay tile like you would use on any tile floor.
I use Duncan ceramic paint or any paint I can "borrow" from my dad. You can draw out your painting beforehand if you want, but when I do abstract type designs like the ones I'm doing here I just start right in throwing paint around. The tricky part with these paints is many of them look nothing like the color they are going to be once finished.
This is taken shortly after getting the paint on ~ it dries fast if you put a thin coat on, but in areas like the circles I wanted a more consistent color so I put it on thicker which takes overnight to fully dry.The clumps you see are from the paint I used that has little crystals in it that explode with star-bursts of color. Even after painting the entire surface you still get areas where the paint is inconsistent after firing. It's sort of like the prize in a box of Cracker Jacks ~ you never know what you're going to get which to me is part of the beauty.
After they are fully dry I load them up in the kiln, use a 016 cone, gently close the lid while whispering a prayer and hit the power button. A cone 016 gets to a temperature of up to 1400 degrees before it bends the cone and shuts the kiln off. I don't go near the kiln until the next day and still the clay is warm.
Every time I approach the kiln to see what the end results were my heart picks up a beat with excitement and fear. I lift the lid looking heavenwards saying "please don't be cracked, please don't be cracked". It's like opening a present every time!
The end results
Here I used some I painted for the front entryway at my gallery as accent tiles
