eoteceramics Posted February 3, 2015 Report Share Posted February 3, 2015 Hi all, I hope someone can help with this. I came across some work by a potter who said she used chalks over slip to draw on bisque. I can't remember her name but her work was beautiful. Im trying o find these chalks myself, does anyone have any experience of using them and any other info about them. I have tried the crayons which were useless as was the pencils. I cant find them in my usual supplier (Ireland) or the UK. Thanks Julia Link to comment Share on other sites More sharing options...
ayjay Posted February 3, 2015 Report Share Posted February 3, 2015 Info about them from Amaco's website is the only help I can offer. http://www.amaco.com/shop/product-462-underglaze-chalk-crayons-lead-free.html Link to comment Share on other sites More sharing options...
bciskepottery Posted February 3, 2015 Report Share Posted February 3, 2015 You can make your own by adding mason stains in the color of your choice to dry white porcelain clay body, add water, wedge to blend the colors, and roll into a pencil/crayon. Let them dry and use them as a stick of chalk. Link to comment Share on other sites More sharing options...
Marcia Selsor Posted February 3, 2015 Report Share Posted February 3, 2015 I have used the chalks in my classes at the university. Students liked drawing with them. too much in one area can cause crawling. Mostly good work came out of their use. Link to comment Share on other sites More sharing options...
Cavy Fire Studios Posted February 3, 2015 Report Share Posted February 3, 2015 Ahh, underglaze pencils! I have used a black one before, and it turned out very nice. I do prefer to use liquid underglazes, though. Duncan and Clay Art Center of Tacoma are my favorite brands. Mason stains can be tricky, since some are heavily refractory (i.e. the degussa colors), so a flux needs to be mixed in at varying ratios to avoid refraction. I use gerstley borate. ♥ Link to comment Share on other sites More sharing options...

Pardon my ignorance here...... a couple of questions: 1) Does it have to be porcelain? 2) Does it have to be dry? 3) Could I just add some mason stain to wet Georgie's G mix clay?

Cavy Fire Studios Posted February 4, 2015 Report Share Posted February 4, 2015 A) Nope! White clay shows the colors up best, though, unless you're using white mason stain of course. B ) It's easiest to mix mason stains as powder with clay. Same with with the flux, if you are gonna use them in an underglaze fashion. I have a lot of ratios if you are interested. C) Yes ma'am!

No. You could use white stoneware. I use/prefer porcelain because it is whiter after firing; some stonewares tend to be ivory and that could affect your final color. 2. No. You could wedge mason stain (with water) into wet clay. I use/prefer porcelain as it allows me to measure ingredients and get more even distribution of the mason stain than I can by wedging. You can just let some clay dry out and then crumble it to dust (which is what I do). 3. Give it a try. But mix the mason stain with some water to make a thick paste; that is easier to wedge than just dry mason stain. I learned from a Mitch Lyons video. Robin Hopper describes a similar process in his books. As with most things in pottery, there are as many ways to do something as there are potters doing it and there are many right ways to do the same thing.

eoteceramics Posted February 4, 2015 Author Report Share Posted February 4, 2015 thanks for all your help everybody, I may try to make my own with the Mason stains although I hate the technical stuff. I found them in 'the big ceramic store' but unclear if they ship to Ireland . Link to comment Share on other sites More sharing options...
oldlady Posted February 5, 2015 Report Share Posted February 5, 2015 you could contact Mason stain co and ask if they have a distributor near you. Link to comment Share on other sites More sharing options...
bciskepottery Posted February 5, 2015 Report Share Posted February 5, 2015 I'm sure there are European companies that make stains comparable to Mason stains made in the U.S. Link to comment Share on other sites More sharing options...
