Grantc909 Posted March 22, 2017 Report Share Posted March 22, 2017 Hello, I am a student at nottingham trent university. I am working with Earthenware casting slip Specifically semi porcelin casting slip from pot clays. I am wanting to acheve a matte black finish for that scandanavian sort of look. I have attached a picture to show the matte black finish i am looking for. Any info on where i can buy this stuff or how achieve it would be a great help! Thank you Link to comment Share on other sites More sharing options...
High Bridge Pottery Posted March 22, 2017 Report Share Posted March 22, 2017 Can't see any pictures but they sell black stain that you could add to the slip or I found this "Black: I used to use: manganese dioxide 6%, red iron oxide 1%, cobalt oxide 1%, but now use 6% of a commercial stain" Link to comment Share on other sites More sharing options...

neilestrick Posted March 22, 2017 Report Share Posted March 22, 2017 Still no picture. Will the surface need to be food safe? Link to comment Share on other sites More sharing options...

Neil Esteick, yeah i would like it to be food safe if possible, im just creating a model mockup so if its easier to not be food safe then thats an option.

High Bridge Pottery Posted March 22, 2017 Report Share Posted March 22, 2017 Nice to meet a fellow northerner. Looking at the pictures it will be better to use a black glaze than colour the clay. You have a couple of options, potclays or ctm ceramics probably sell an earthernware glaze that you could use that is the right temperature or you could find a satin transparent glaze recipe for the temperature you need and add colouring oxides (iron, manganese and cobalt) to make black. If you don't need much glaze you are probably better off going commercially made. Link to comment Share on other sites More sharing options...
Grantc909 Posted March 22, 2017 Author Report Share Posted March 22, 2017 By any chance have you got a recipe or know where i can get a recipe for an intense black matte? Link to comment Share on other sites More sharing options...
Joseph Fireborn Posted March 22, 2017 Report Share Posted March 22, 2017 There are a lot of black matte recipes, but you are going to have to test them a good bit before you find one that you want with that quality of sheen in those pictures. I would probably start with this old thread: http://community.ceramicartsdaily.org/topic/12733-best-food-safe-cone-6-black-satin-matte/ Link to comment Share on other sites More sharing options...
Grantc909 Posted March 22, 2017 Author Report Share Posted March 22, 2017 That,s a great help, Thank you. I have been advised to do testing but I am just conscious of time since my major project has to be handed in soon. I thought it would just be as easy as picking a colour and mixing it. Thanks again for all your help ! Link to comment Share on other sites More sharing options...
Joseph Fireborn Posted March 22, 2017 Report Share Posted March 22, 2017 I thought it would just be as easy as picking a colour and mixing it. I wish, but no this isn't the case. If you want this then your going to have to go with a commercial glaze. And even that will still need testing before committing it to your project.

Chilly Posted March 23, 2017 Report Share Posted March 23, 2017 There is a commercial glaze called ..........heirloom silver...????? I think. Anyway, it fires to a matt finish, similar to the first link, It's not black, but not definitely not silver either. I'll go down to the studio later and see if I can find the pot and sample.
