Underglaze vs. Watercolor

I usually only fire my work twice. A first bisque fire to bake the clay enough to glaze, then a final fire to melt the glaze into solid, shiny glass. But when a piece involves detailed painting, I fire it three times.

I rarely do this. An extra bisque uses extra electricity. Sometimes I even paint straight on greenware—unfired clay. But these pieces took so long—a second bisque sets the underglaze so I can apply glaze without risk of smudging. I’ve done this before. A finger brushed against underglaze that was once dry but was dampened by wet glaze. So frustrating!

A second fire also gives me a chance to correct mistakes. Like if the burgundy comes out too streaky, the way it did in my test tile, I can touch it up before sealing it forever under glaze.

Underglaze is strange. It's like watercolor but also not at all like watercolor. They share the same binder—gum arabic—so you can thin them and mix them the same way. You have to work quickly. Bisqueware absorbs water even faster than cotton rag, each brushstroke disappearing into the clay almost immediately. Wet on wet is next to impossible. And you layer colors the same way, light to dark. You can overpaint light on dark, but when it fires, the dark underpainting bleeds through no matter how many layers you put down. Because the particles move and bleed into the glaze during heating. Because science.

I boldly did a red imprimatura on one of my first ceramic frames, thinking it might show through a little. Oh no. It was a red mess with translucent scenery floating over it. You can see it in the photo below. I eventually put a gold luster rabbit on it and gave it to a friend. Lesson learned.

I use high-quality brushes for watercolor—brushes that hold water for long fluid strokes, brushes that keep a fine point. For underglaze I aim for the same, but the clay absorbs water so quickly there's no such thing as a long fluid stroke. And high-quality brushes are useless since the clay particles in the underglaze get trapped in the bristles and sabotage the fine point pretty quickly. I reach for smaller and smaller brushes so that even when they're splayed from clay, they're not too wide.

The biggest difference is how colors change during firing. With watercolor, what you see is what you get. With underglaze, the end result will be much darker. Or sometimes lighter. Sometimes it barely shows up at all. Your carefully planned color theory can fly out the window as soon as the kiln shuts. Science again.

I made test tiles. Little pieces of Standard 182 clay with one, two, and three coats of each color. I keep them on my table when I paint, a tiny taste of before and after. It gives me an idea of what to expect, which colors will be reasonably accurate and which will need more care.

Ceramic Paintings

I got into ceramics because I wanted to draw on three-dimensional forms, to make hopefully-beautiful sculptural things for my home. So much of what I do is for other people—commissions for books, cards, gifts, the occasional magazine. These are for me.

Which makes it strange that the project I'm most drawn to is a series of ceramic framed paintings. I take the time to mold three-dimensional canvases just so I can paint on them in two dimensions anyway. But also not strange at all. Few things move me more than an old framed canvas.

I love old paintings. The feeling of standing in a museum, surrounded by exquisite art hung salon-style on jewel-toned walls. The Walters in Baltimore does this—grand rooms where paintings and curios are displayed the way they might have been in their time. Light peeking in from tall, shuttered windows. The cabinetry. The quiet. The sense of stepping into a world gone by.

These tiny ceramic paintings are an homage to that.

The latest set is in the kiln now, getting a second bisque fire. I'm hoping the colors warm up without getting muddy—sometimes brown pigment takes over during firing, swallowing the greens and blues I mixed so carefully. I’ll share them when they’re done and we can compare together. I'm hoping the details hold.

The idea was to keep it simple. Paul’s never been big on dressing up, but we had a Halloween party to go to, so I figured fancy masks with regular clothes would be a good compromise. A paper mache jackal mask for him, and a mushroom hat for me. Why a mushroom hat? Because I wanted to play with LEDs and I wasn’t sure how to work them into a rabbit mask.

I went to the art store weeks before Halloween because I really couldn't put it off any longer. Bought supplies, but didn’t actually start anything on account of being knocked out with flu and covid vaccines.

When I finally did start, I got to work with sculptural mesh for the first time. It’s like fine chicken wire you can shape and fold.

And like chicken wire, the edges are really sharp. It wasn’t long before I put on my gardening gloves. I probably should’ve watched tutorials, but I dove right in, making little origami folds to create the jackal's snout. I shaped the rest of the head and then affixed mesh ears with aluminum wire.

Then I made the mushroom cap using bowls to give it shape. I went on intuition, using the part of my brain that's good at form and mechanics. I got the hang of it quickly.

The paper mache came next. I cooked up some paste with flour and water, then used it to adhere torn newspaper strips to the mesh. Very elementary school. The mushroom cap was a breeze.

The jackal was a little tricky around the ears, but I quickly found smaller strips made for smoother corners.

It seemed to work fine, but when I painted a coat of white acrylic on the mushroom cap, every crease and buckle showed up. I did some research and discovered I could smooth it with drywall compound. I also learned I could make my own paperclay, which should eliminate the problem altogether, so I’ll try that method next time.

I applied a thin layer of drywall compound to both headpieces, then used a damp washcloth to smooth it down. Once dry, I painted the mushroom cap again. Not perfect but better.

The jackal mask was still rough, but all the painted details concealed it a bit.

For Paul's mask, I wasn't sure about the eye holes. I considered them in the very beginning, but decided it would be safer to add them after everything was formed and painted, and I think that was the right call. I had Paul try it on to figure out where his eyes actually were. Turns out they were right about where the jackal’s eyebrows could be. I used an awl to punch small holes, then shaped them by cutting through the mesh and paper mache with an exacto knife. Added nose holes too, to make it more breathable, though I'm not sure it ever became super comfortable.

But really, it just needed to be wearable for a few minutes at a time. Halloween masks get old quickly when there’s beer at hand.

The mushroom hat got LEDs. I took the awl and made holes all over the cap, threaded lights through, then capped each one with hot glue. The whole time I was thinking I hope the batteries don’t die before the night is through.

At the base of the mushroom hat, I made a cardboard frame which I covered in chiffon to resemble gills—this part sat on my head, attached to the cap with double-sided carpet tape. Then I added a white chiffon veil to cover my face, and ribbon ties out of old tulle so that it wouldn’t fall off the moment I leaned over.

the mushroom costume in all her glory

At the party, I met a neighbor dressed as a voodoo doll. Her costume was fabulous. Pins sticking out everywhere, full outfit, mismatched shoes, elaborate headpiece. I thought it looked like exactly the amount of work I was trying to avoid. Meanwhile she thought mine sounded like a ton of work because of the paper mache and LEDs.

Her partner came as JP Prewitt—David Duchovny's character from Zoolander. He crafted his homemade hyperbaric chamber from a plastic display dome and an LED strip. He had my vote for the costume contest.

He tied for second. I came in third. There were four people tied for second, so take that as you will.

Most people knew I was a mushroom. Some thought I was a samurai. One trick or treater asked if I was an angel. Another asked if I was a forest maiden, which struck me as very funny—forest maiden was in his vernacular. One kid informed me that mushrooms are red. One man said he knew what I was because "I eat a lot of mushrooms."

I'll definitely do more mask making in the future. Maybe not until next halloween, but certainly at some point. It’s always nice to have an excuse to play with a different medium. Working with sculptural mesh felt inspiring in a way I didn't expect, despite the fact that I now know what they mean by “death from a thousand paper cuts.” And there's something satisfying about making costumes that are fully one-of-a-kind, even if they're a little uncomfortable and take too long and some kid thinks you're a samurai.

One of the people who tied for second was at another party I went to on Saturday. It was nice to have that connection, to recognize each other from the Halloween party. Small neighborhood moments like that are why you spend weeks making a mushroom hat in the first place.
