I’m a big fan of your work, I bought a small raven witch from you, which I love and cherish, and I was wondering if I could ask you what kind of tools you’re using for your sgraffito?
I’m getting back into ceramics myself, and I just got a little jackalope cup back from the kiln, where I tried to sgraffito détails in my slip, but the cobalt was meltier than I anticipated and it covered most of them. I think I need to work on my application, but also that a thicker line might help, and I was wondering what you were using?
You can check my stuffs at @unnamedartist-portfolio if you want, and if you have any advice, I would be so honored to hear them!
Hope you have a fantastic day! :)
Hello @iam-adreamwalker! My apologies for taking 500yrs to reply to this - I've only just now found the time to take some better photos of my sgraffito gear.
These are basically all of my sgraffito tools, but you definitely don't need this many (I just have a pottery-tool-buying PROBLEM). My core tools are the ones to the left - the two pointy sticks & the two carve-y guys. Both of the wire loop tools are by Kemper, and I'm not 100% sure the brands of the sticks. The colourful set is from Xiem and is nice if you're doing a ton of sgraffito work, because it offers so many options for carving! I especially like the round-loop tools for carving feathers.
Here are some close-ups of my main tool gang:
I especially like the darker-brown stick tool because its point is slightly rounded, making it easier to scrape the slip off the surface of the clay vs. just making a deeper line that won't be as dramatic (more on technique later!).
Speaking of rounded-tip tools, I just realized I forgot my other favourite, a core tool that could replace the lighter-wood pointy stick in my Most Important Sgraffito Tools ranking - the ball-ended, double-sided stylus! This thing is a tiny powerhouse and, like the more rounded point on the dark-wood stick, it gently draws the slip off the clay rather than gouging:
Next up, slip! I'm not sure what you were using as your colour layer, because you mentioned that it ran/moved on the surface of the clay, which my stained slip doesn't do. Did you mix glaze into the slip? Or were you working with a powered pigment?
When I'm making coloured slip, I use a powdered pigment called Mason Stain, which can be used to dye slip, clay, and clear glaze bases (eg. to make translucent celadon glazes). I use a couple different brands, but it's all called Mason Stain.
If you're a sensible person you can find proper recipes for mixing the slip and the stain, but I honestly go by how it looks - I add it to the slip a few spoonfuls at a time, mix, and see how pigmented the slip looks. If you want to really make sure the pigment is well-mixed you can get a stick blender from a thrift store or attach a mixing head onto an electric drill (something I'd like to upgrade to as the stick blender is SUPER messy & hard to clean out), but I mostly just mix it really well with a stir stick.
Once it's mixed, I keep my slips in these little self-sealing glass containers from IKEA, which stop it from drying out too fast (I tried keeping slip in regular jars & it turned into a rock...you definitely need a container with a rubber seal on it!). You'll still need to add water here & there, but it can sit for weeks without too much concern.
My slip is a little thick & gloopy, so I usually brush two layers of slip onto the leather-hard sculpture, letting each dry before I put on the next coat, and I let it dry until it's no longer at all tacky before I start carving (otherwise things WILL smudge and it WILL be terribly messy.
Finally, technique! I did take a look at your blog & the sgraffito project you mentioned & one thing I noticed was that your scratch marks were very deep and didn't reveal much clay under the scratched-away slip. This is an easy thing to have happen, especially if your slip/clay/both are still too wet or you're putting too much pressure on the carving tool.
My best tips for remedying this are:
Make sure the slip isn't at all tacky to the touch & that the clay underneath is leather hard.
Go very gently at first! It doesn't take much to scratch the slip away and you can always come back and take away more slip/make your carving area deeper if you want to, but you can't put the clay back!
Use the carving tools at an angle to the clay (somewhere around 45º ish, this is not a hard science), not perpendicular to it - this will stop you from stabbing straight down instead of scraping. If you've ever done linocut prints, think of the angle you hold the linocut tool at - sgraffito is generally a pulling-towards motion vs. a pushing away one for lino, but the angle is important either way!
Having even just a small variety of tools (eg. my core 4-5 as shown above) will also help, as you'll have options for line-weight/how much slip a tool takes off.
Phew! I sort of got carried away there, but I hope this was helpful?? If you have any more questions (or if anyone else does), please don't hesitate to ask! I'm still planning on making a proper sgraffito tutorial/series of tutorials, but need to find the time for all the filming/editing that requires.
