So tonight I put some “finishing touches” on the mugs!
As part of the soda-firing process, a lot of the color accents achieved
come from colored slip applied to the surface. Slip is just watered down clay
with special chemical colorants added. These chemicals react to the
soda atmosphere and create dramatic colors and random flashing marks.
Slip generally needs to be painted onto the clay body while it is wet
or leather-hard. I typically paint the slip on after stamping, trimming
and applying handles. It’s usually the last step before I let the pieces air-dry.
Tonight I painted slip accents onto the mugs… both along the top rims
and some of the smaller details inside each of the stamps. Yes, it’s true…
each and every little stamp, one by one… each one with a touch of slip!
Now that they are all painted, I can let them air-dry… and then bisque fire
the mugs when I accumulate a kiln-full of greenware (dry clay). Once fired,
the mugs will be glazed and fired again. A few more steps in the process…
can you show me or tell me how do you get the pattern to make stamp . thank you.
I make my own clay stamps for the impressions. It’s simply a coil of clay rolled out, and then I carve a pattern into both ends while it is still soft. When they get a little drier, I carve my name on the side as you know how things “travel” in the studio?! Then they need to be bisque fired – to make them hard, yet keep them porous. You do not want to high-fire them – as they would then allow the clay to “stick” after each impression. I typically sit down and make a dozen or so at a time. Just let your mind wander and make a bunch. Inevitably, you’ll love some and others not so much. But the more you make, the more you have to use later!!! The next time I’m making more stamps for myself, I’ll try to document it and do a blog post. Thanks for asking!
