Slip Trailing and Layering Ceramic Underglaze to Create a Patina

This clip was excerpted from Layered Surfaceswhich is available in the Ceramic Arts Daily Shop!

There are a ton of fun pottery decorating techniques out there involving slips and underglazes. And the technique in today’s video is another fine example, and one I hadn’t ever seen until filming Erin Furimsky’s Layered Surfaces DVD. So, I thought it would be a good one to share.

In this technique, after slip trailing some patterns on a piece, Erin paints a couple of layers of different colored pottery underglazes on top. After everything dries to bone dry, she sands and scrapes away at the layers creating an effect similar in appearance to layered and peeling paint. And it is gorgeous. – Jennifer Harnetty, editor.

    i loved watching the technique..but it would have been nice to see a picture of the finished product.

  • Penny O.

    Thanks Erin; that has spurred some very interesting ideas using variations of your technique.
    Thnaks for sharing!

  • I love the idea of layering. You painted the underglazes while the piece was leather hard, did you do the scraping while leather hard or did you bisque first? Also, what did you use for overglaze for the final firing and at what temperature? Also, what type of underglaze did you use? Thanks so much for sharing and I love your work.

  • Lana K.

    The technique was very intriguing, but

    it would have been very helpful to have seen the finished, fired cup.

  • Jennifer H.

    Folks,

    I posted a detail photo of the finished glazed and fired surface above. It is from the test tile that Erin made for the DVD. She used the exact process demonstrated above to get this look. It was shown briefly in the clip above and more on the actual DVD. Hope that helps.

    Thanks,
    Jennifer Harnetty

    I liked the technique shown very much. Could you use this technique at higher temps, say stoneware? Thanks for sharing.

  • Gail L.

    Not everyone is able to hear. As I have a severe hearing loss and am unable to understand her comments, I would like to know if she bisqued the item first or is working on leather hard clay

  • Janet T.

    Layers, layers, how many layers needed ? Yes, think. Invent – try ideas –what is needed ? sometimes the answers come out of the most wierd places ! I love it !!!

  • Nikki L.

    I hope I can buy the DVD in Holland! I like youre work very much..
    My compliments for you!
    Greetings Nikki

  • Did you put the clear matte on after scraping and then did Only 1 firing?
    Or a second firing with the clear glaze?

    Thank you the technique is great!

  • I always, always want to see the piece finished, not something “like” it. It should be a standard requirement for even having your video shown on CAD. After firing, edit a photo of the finished piece in at the end. Having said that, nice technique – thanks for sharing!

  • Patti C.

    I appreciated the detail of the finished tile, but it is a common feeling I have after these videos…I would like to see the finished piece, not just something else that is sort of similiar. I realize that not all of the pieces we see demonstrated will come out as hoped,(I know my percentage of pieces that turn out well can be pretty low at times) but it would be something to try to include when possible.
    Loved the idea of this technique and will try it!

  • Charlotte B.

    Is there a dust issue from the sanding and scraping or is the slip and underglaze damp enough to keep the dust from becoming airborne?

  • Shirley D.

    I too would love to see the finished cup. I was so looking forward to it and felt let down with just the tile demo.

  • thank you again CAD for your generous sharing of techniques and inspiration. Many artists hold their methods close to their chest and its wonderful to see here such a library of ideas! I love Erins surface finishs so much 🙂

  • I love how she did this, but I am wondering how you get green and yellow slip? I’m just a beginner, to be honest and I know what slip is, but I have never seen this color. Is there a color additive in this? Thanks for the great video. I’d really love to try this sometime.

  • Maria B.

    Thats a great way to get depth of colours in lower firings. Thanks so much for sharing this,

  • Masha B.

    Dear Erin and Jennifer! Do you make your underglaze or it comes as commercial mix? Here in Russia we get only powdered version. Is it a glycerin that makes the underglaze so oily looking and allows to put one layer on top of the other?

  • Lynne N.

    I enjoyed this video, and especially liked the tip about sanding first and then following up with the rib. I am another who would have liked to see the finished cup (it wasn’t clear that the photo was of a finished test tile.) I also am wondering if the slips were commercially prepared or if Erin colours her own. Great technique,thanks for sharing.

  • Janie V.

    I purchased the DVD and it was definitely worth the money! There is so much on the 2 discs, I don’t know if I will EVER get finished trying all of it! I have a good ‘recipe’ for colored slips, let me know if you want it.

  • Sara N.

    this was an excelent clip! I just finished some cups and I’m going down to the studio to try this technique right now!! thank you!!

  • Janie, would you share your colored slip recipe?
    I have tried this on a vase. Looks so great! will be buying the DVD!

  • Linda W.

    Hi I live in England and I can’t find the slip trailers Erin uses over here only rubber bulbs which are too stiff for me,does anyone know where I can buy them? I am a hobby potter but love using slip and would like to try these techniques.Any help would be much appreciated.
    This is a FANTASTIC site for me to learn new methods.
    Thanks very much to everyone involved.
    Linda

  • Debbie H.

    Bath Potters Supplies have ‘precision slip trailers’ which are very similar to the ones Erin uses.

  • Shimona K.

    The difficulty with seeing only the finished tile is that the cup had another detail on it–a flower pattern that was partially covered by the slip overlay. It would have been valuable to see the whole finished product, because the tile only had the circles, dots, and underglaze.

  • Rosemary B.

    It would be great if we could see the final results of all the demos. Sometimes it’s hard to visualize the final product.

    Thank you for always having such informative videos.

  • Marlies B.

    Thanks for posting this, I love the technique and the results look great!
    I have started to use underglazes but have some issues… My ug burn out, I think I use the wrong glaze on top. Could you possible give me a glazerecipe for ^6 that does work?

  • Debi D.

    As usual, you did not show the finished piece. I’m not sure why you always do that. It certainly does NOT make one want to buy the book. It angers me every time!

  • Sheila L.

    PLEASE, show the finished piece on these videos. Seeing it pulls the process together in the viewer’s mind. Without it, the video is far less effective. Every time I see one of these videos it seems there are lots of requests to see the finished piece…even a glimpse of it, but nothing changes.
