Chrysanthos Underglaze pencil best for use on bisque or greenware fires up to cone 10 in a ceramic kiln color (black in color) 1 pencil included.

This pencil works great to write initials, message ceramic bisque before glazing. Definitely recommend.

The black and blue pencil under glaze work great for painting eyes. Good Color for both pencils.

I was trained for 7 formal years in college and 40 years informally making art. I never questioned it as it started around 7 with the capacity to bring me pleasure. I don't overly question pleasurable pursuits or look them in the mouth. Prints, drawings, paintings, the works filled my days. I have good drafting skill. Better intuitive ability, I worked under some "names" and have heard some fantastic lectures. But ceramics was an area I did not "discover." I didn't excel there in college and I couldn't center. The dept. in college was conducive to a relationship, say over a few good pointers on hand building and they bragged about who they had ...ummm...shall we say demi glazed. Anyway I never quite made the area my own. I actually had to exit rapidly. As a result it's been something I either then felt as foreign, tried to see as outside my skills or just envied.So now I have access to a kiln, we have a wheel, clay, glazes because essentially I married an artist who works sculpturally. Married so that I might not have to explain myself. ( I'm not sure that worked out) Art is a talent and a drive and mostly just a way to pass the days creating over negating, talking, criticig or judging or whatever. I like the part where you take clay and get a bowl. My current run is bowls. I have made about ten.About 45 to go. NOW, I finally get to this "pencil."What I am good at is drafting, drawing, mark so ceramics isn't second nature at all. Glazes are a hell of an art.. I'm gestural and this pencil allows me to draw on the pieces. I'm retaining what "I know" a little using it.Now I've read in the net others making their own pencil and bemoaning the loss of other pencils of old due to toxicity. That I'm too inexperienced to know about so this may not be much to an experienced potter. What I do know is I've now got fair drawings on my bowls. I haven't used them on greenware, I've used it on bisque. But it says it will work on the greenware so I need to do it. I'm going to try one and see. The effect is a bit grainy on bisque, that's annoying and I notice some was lost firing but it has allowed me to transition into this art form keeping the skills I do have relevant, so I'm not so out of place I can't make anything worthwhile. I need a line, so this pencil works here at the moment.It clearly says not to use a sharpener on these pencils for a practical detail but I did and the company is correct they need to be sharpened with a knife. I cut open my palm once and shy away from knife sharpening because the stitches left a scar ...back...in printing. Because the sharpener kind of works I'm happy. Nothing to brag about but just so you know you need to mess with that with them. I used a pencil on two small bowls so they are expensive and go very quickly. You can wet them and paint over them keeping your line. I glazed over them and the lines appeared through some pretty thick glaze. The effect as I manipulate it is a bit too grainy so I'm going to tackle that with some serious work, try brush wet, wetting as I draw. The bowls right now are leading me to experiment, rethink, retry and seek ways to better forms and surfaces.I bought this in a set of 6 colors. Need to re-order twenty of them. Ah for the $.

Needed a means to write on pieces before glazing. Fillls the bill. A little pricey but then it should last a long time.
