Ceramics II Glazing the Platters



hello there this video is for my ceramics two students who are going to be plain painting their platters that we did the slab platters that we created have an incised design the incising creates a nice little barrier between two different colors of glaze so the glazes will not spill over and bleed and touch one another the first thing that we're going to be doing with your platters is we're going to be putting the barrier glaze on the inside now what we're going to be using is an under glaze I already have the under glazes in little squeeze bottles up on my desk you can just grab one of these they all should have something in the tip of a squeeze bottle I often put pins or paperclips anything like that that will help to prevent the tip from getting clogged what you're going to be do and doing is you're going to be just putting this black in all of the grooves actually I do have a few other colors if you wanted to choose some of the other colors you don't have to stick with the black I'm using black because I like the nice contrast when you go to do this you want to try to be as careful as you can but if you get it outside the lines it's not a big deal because I will show you how we can remedy that and I'm just going to go ahead and continue with this okay now that I have finished doing the black underglaze and all the lines I'm just going to re plug that so it doesn't get clogged and I'm going to take a clean damp sponge and I'm going to sponge off the excess where perhaps it came up and out of the lines I'm just going to try to clean up the surface a little bit now I will want to be aware that my sponge will get kind of dirty so I will need to be cleaning my sponge off periodically now that my underglaze has been sponged clean from the areas surrounding the lines I'm ready to start with my glaze the glaze that I'm going to be using of course is a stoneware glaze remember that the glazes that we have are cones five or cone six this is a coyote glaze when I open it up I want to stir it first I want to make sure that it actually is a nice even consistency if there's things up on the wall I want to mix that up and stir it in the method of application that I'm going to be using is the bulb syringe I like to use this so I can get some nice detail painting the bulb syringe has a little tip that is very similar to a tip that you would use maybe to inflate a like a basketball or something it just doesn't have the hole on the side the tip just kind of Wiggles in and it stays in by friction now the bulb syringe works if that add a little water in it if you squeeze the bulb insert it down into the glaze and then I kind of wipe that off and then if I turn it over and kind of shake the glaze down in there I can feel that the glaze just went to the bottom I'm going to squeeze out a little bit more air and I'm going to fill it that way you can try it two or three times until it feels full it feels full now I'm going to go and put the tip in and I'm going to go wipe this off now that my bulb syringe is full I have my tip back in its cleaned off and I am ready to apply the glaze now the glaze is applied by taking and putting the tip near one of the black lines and kind of going up to the black line I want to attempt to be careful to try not to go in the line if you do accidentally get glaze down in the groove it's not a tragic or anything you can always chip it out with a needle tool but it's just much easier to try to avoid getting it in there you when you're done using a glaze you need to make sure that you squeeze all the extra glaze from the bulb syringe back into the jar and then we need to wash this out washing out a dirty bulb syringe is not difficult if you do it right first of all I am going to use a container to catch water I'm going to do a quick rinse and I'm going to put the bulb syringe down into the water and I'm gonna squeeze it out many times yeah after squeezing it out several times I'm going to fill again with water clean water and you can see when I just rinsed that it looks much better we got to do it one more time this time I'm going to fill it with water I'm going to run it and completely through the tip and then the test to see whether or not there's any glaze in it as I will squirt a little bit of that water on there if you can see any glaze residue in that you know it's not cleaning up this is clean I need to check all of your bulbs oranges when you're done using them before we put them back if they are not properly cleaned it will clog and ruin that tip take your time and be careful as you glaze your platters in your plate to make sure that they have the best result that they can and make sure that you fill out your kiln ticket with the correct glazes and cones on there and you can put them in the drying cabinet if you choose to do the back side please make sure that you have plenty of clearance you

    Hi Karan 🙂 do you like using squeeze bottle or bulb applicator? Trying to buy applicator for under glazes but I don’t know what is better.

    You have excellent informative videos. Couldn’t you use a syringe to fill the bulb and be so much cleaner and not waste the glaze on the outside of the bulb? Must be a neater way.

    Thanks so much for this, you've explained it really well. I've just bought a kiln and supplies and I am so excited to get back into ceramics after a fifteen year baby-break! This time with no pressure to sell, just to have fun for a few months whilst a learn new skills, and then look to sell in craft shops/etsy etc. I'll look for more of your tutorials as they are so clear and helpful.

    Where do you purchase the Standard 153 stoneware clay?
    Which cone of coyote brand glazes do you use?
    I looked on https://www.coyoteclay.com/BuyUnderglaze.html but I didn't see any specification of different glazes for different cones. Watching your video, do you only used underglazes on this piece? How long do you fire and how many different steps do you take for firing this piece? Not sure if you only fired it one time….
    Thanks so much Karan!

    Hi Karen,
    Why are you not painting on the glaze? Does using the bulb cause a thicker application so you don't have to go over it again? I know when you paint on the glaze you have to apply 3 coats. Thanks so much for this very informative video! Keep them coming.

    Hi Karen, Thank you for your reply. I am taking pottery class at my church given by a retired teacher who does it as volunteer work. The church supports most of the funds and students contribute minimal amount for pottery supplies. It's a group function which allows only so much of individual's choice in glazing color or type of clay. Because I'd like to explore varieties in glazing color, I plan to get my own glazing materials but I have to comply with their firing temperature so that my stuff can be bake together with other student's at the same time. ( they use cone 5, 6).
    Right now I am in a stage of pulling straight cylinder ( I used your technique, and it worked like charm!!) and in near future, I plan to throw a big bowl or plate using sgraffito technique you had shown. I really appreciate your efforts for uploading all those videos and I am sure there are many people around the world using it as their guidance. You are an amazing artist! Thank you again. Millie

    Hi Karen, I' d like to know what kind of underglaze you are using and if the firing temperature is compatible with Coyote cone 6 glaze. You are showing a wonderful technique and I'd definitely like to try it.

    @Lynn Woodward-  Hi Lynn!
    One of my goals for this lesson specifically was to teach my students how to use the underglazes and bulb syringes.  The reason that we use the underglazes first in the grooves is to wipe off any messy areas prior to using the stoneware glazes.  If you use the underglazes after you glaze the platter, and it squishes out into the glaze area, it is much more difficult to remove the messy underglaze.  If the underglaze is placed on top of the regular stoneware glaze, in our case, it looks messy and blurred.  My goal for the kids is to be able to paint very detailed areas with the red bulb syringe.  They find it much easier than using a tiny brush… and they can do it with a much neater application.  Many of their designs have quite intricate details which may require the use of the bulb syringe.  I hope my explanation makes sense why I teach them that way!  🙂

    Hey wouldn't this have been easier to brush the glazes on then add the underglaze to the grooves later? Ouch with the squeeze bulb all day!
