Hi. It depends of the chemistry, but commonly I don't. I do however usually add fiew drops of epsom salt (saturated solution of MgSO4), it helps to improve the viscosity of the glaze and the glazes don't settle so easily.
Hi Marcia. I use two different red stoneware clays, G&S 375 (firing cone 5,5 ) and G&S 551 (firing cone6). Its nice red-brown colour when fired. Its mustard yellow when green, nice orange when bisque friend. The higher it fires the darker it gets. I added the pictured of the fired bowl to my blog, you can see it here: klementiart.com/en/behind-the-wheel/how-to-brush-glaze-a-bowl/
Indeed, we can. And there are also commercial clays that fire buff or yellowish colour. I have used one clay that Is dark brown as mud when fresh, but fires to beautiful buff colour.
Since they are brushing glazes do you put on 1 coat and let dry then another coat or use thicker amt applied coming out of bulb? Looking forward to trying this technique, thanks for sharing.
Hi. No I don’t let it dry, I just move few times up and down with the bulb and brush and keep the pot spinning until the glaze is not flowing on the pot any more. It dries quickly. I make my glaze thinner than the common brush on glazes, however those work well also. Just one downside - if there are any even smaller clumps in the glaze, the bulb will get easily clogged.
That is very clever. Thank you
Glad it was helpful!
Hi…thank you for this.
Do you add a glazing medium such as cmc gum to the glaze you mix?
If you have time, please reply

@@klementi-art thank you It will be nice if the mustard colour stay after glazing fire, but also we can use maison stains to colour the clay. 🤗

@@klementi-art Awesome and thanks so much for your detailed reply. So much faster and you get an even coating. 👍😁
