docweathers Posted February 24, 2019 Report Share Posted February 24, 2019 I'm just beginning to work with colored majolica on bisque and greenware.. What is the best way to mask this off so that subsequent glazes don't get on? Link to comment Share on other sites More sharing options...
Babs Posted February 24, 2019 Report Share Posted February 24, 2019 Is your majolica drying soft or hard? May need to sinter it to be sure as some majolicas lift on laying on onglaze colours or wax. Difficult to do without messing the design If hard..liquid wax but if it messes the decoration sintering may be the way. Link to comment Share on other sites More sharing options...
Callie Beller Diesel Posted February 24, 2019 Report Share Posted February 24, 2019 I took a workshop from Rosalie Wynkoop once, and she'd spray the surface down with laundry spray starch, or I imagine hairspray would also work. Link to comment Share on other sites More sharing options...
docweathers Posted February 24, 2019 Author Report Share Posted February 24, 2019 I don't think I understand what you're suggesting. It sounds like you're saying put the majolica on the pot. Then spray it all with starch or hairspray. Then put the rest of the glaze on. However, I don't understand how that would work if that is your meaning.

Babs Posted February 24, 2019 Report Share Posted February 24, 2019 You want the majolica masked so you can glaze other sections with other glazes and not get into the majolica? And if it does it can be wiped off? Callie's spraying will "set" the maj. but it would not repel the other glaze I think. Not having used the spray tech. other than to make the maj lose its softness I can't advise. Thinking, it may harden maj enough for you to lay on liquid wax without spoiling the design Link to comment Share on other sites More sharing options...
Callie Beller Diesel Posted February 25, 2019 Report Share Posted February 25, 2019 Are we working with the same definition of Majolica? I'm picturing you wanting to add a traditional over glaze decoration on top of a white glaze while its raw, and just not wanting the white glaze to smear.

docweathers Posted February 25, 2019 Author Report Share Posted February 25, 2019 What I want to do is have a colored base and then pipe and intricate colored glaze on top of that rather than what I think is more common of extruding a majolica pattern on greenware firing it. Then adding the overall glaze around the majolica... I think?? I'm a backwoods potter with no training other than CAD. Link to comment Share on other sites More sharing options...
liambesaw Posted February 25, 2019 Report Share Posted February 25, 2019 Majolica is a tin white glaze over earthenware used with overglaze for paintings and such. Sounds like you're talking about something else Link to comment Share on other sites More sharing options...
docweathers Posted February 25, 2019 Author Report Share Posted February 25, 2019 I'm calling it majolica because that is the kind of glaze formula I'm using. It certainly not what one normally means by majolica in terms of artform. Link to comment Share on other sites More sharing options...
liambesaw Posted February 25, 2019 Report Share Posted February 25, 2019 I guess I'm having trouble picturing what that would look like. Glazes gonna mix if you're putting them on top of each other, I don't think there's a good way to stop that. Link to comment Share on other sites More sharing options...

Thought you were trying to pipe super thick slip, not glaze. Usually when glaze is really thick it crawls, if you are piping glaze not sure how you would overcome this. Calcining all the clay in the recipe to start with I would guess. I think it would be simpler to pipe really thick coloured slip then put a clear glaze over, don't know if thats an option for what you have in mind.

docweathers Posted February 25, 2019 Author Report Share Posted February 25, 2019 So far no problem mixing and I have just begun to fiddle with the majorica chemistry Signed . Link to comment Share on other sites More sharing options...
liambesaw Posted February 25, 2019 Report Share Posted February 25, 2019 The crawling would come during the firing, have you fired it yet? Would be cool to see a sample Link to comment Share on other sites More sharing options...
Callie Beller Diesel Posted February 25, 2019 Report Share Posted February 25, 2019 Ok. In the name of clarification, what I’m now picturing you doing is having some kind of piping apparatus (cake bag or other) filled with a thickened majolica glaze that has had colourants added to it. You are piping your designs onto greenware, bisquing the piece and then wanting to add glaze to the spaces in between the piping. Have I got that right?

docweathers Posted February 26, 2019 Author Report Share Posted February 26, 2019 Yes that is accurate. I have been putting the majolica over other glaze and this has worked out fairly well except on vertical surfaces. With a runny glaze the majolica takes a trip south. One way I thought of dealing with this was to put the majolica directly on the bisque and then put the general glaze around it. It seems too much work to either use latex or wax resist to coat the majolica before putting on the general glaze. I was hoping someone had found a clever way to make this an easier process Link to comment Share on other sites More sharing options...
neilestrick Posted February 26, 2019 Report Share Posted February 26, 2019 On a flat piece you could just flood it in between the raised lines, like cuerda seca on tiles, but on a round piece that won't really work. Maybe just brushing the glaze on? Link to comment Share on other sites More sharing options...
Callie Beller Diesel Posted February 27, 2019 Report Share Posted February 27, 2019 I agree with Neil. Glaze trailing might be your best option if you don’t want to mess with wax. You can do it on a vertical surface if held horizontally, you just have to go slow. Link to comment Share on other sites More sharing options...
docweathers Posted February 27, 2019 Author Report Share Posted February 27, 2019 I've been doing glaze trailing on vertical surfaces with no problem, until it's fired and the underlying glaze is runny. Then the majolica travels with the underlying glaze. I think my next strategy is going to scrape a thin band of the underlying glaze off where I'm going to apply the majolica. Hopefully, it will get enough contact with the bisque to anchor it. One thing I love about ceramics is that there's an endless number of things to experiment with. I'm more interested in finding new ways of doing things than actually producing pretty pots. Link to comment Share on other sites More sharing options...
Babs Posted February 27, 2019 Report Share Posted February 27, 2019 Could you find a stiff underlying glaze...cant remember but think a recipe was around here..could be coloured by stsining then test if your maj. moves on its vertical surface Link to comment Share on other sites More sharing options...
docweathers Posted February 27, 2019 Author Report Share Posted February 27, 2019 Yes, that works fine when I'm using one of my stiffer glazes. It's my understanding that at adding a little EPK to running glazes tends to stiffen them up. I may try that. Link to comment Share on other sites More sharing options...
