Black Gold Matte C6

[Jan Wallace]

Black Gold Matte

Red Art Clay                                49.0 (I used local red clay)

Manganese Dioxide                       36.5

Ball Clay                                      4.0

Silica                                          4.0

Black Copper Ox                           4.0 (I used Copper Carb 8%)

Cobalt Ox                                    2.5 (I used Cobalt Carb 3.5%)

Bentonite                                    2.0

Brushing Medium                           1.8 (I left this out and dipped my test tile)

 

Black, metallic glaze, Bronze where thinner, black where darker.

Note: my test tile below shows a good colour response with respect to how its supposed to turn out but a rough texture? This could be due to the use of my own 'Local Red Clay' and in such quantities that it is not melting sufficiently at this temp. I am open to suggestions about this please. Thanks

Hi Brian, Thanks for your response and I appreciate you taking the time to answer my question. I did sift the red clay first. I thought perhaps that it might have been a little grainy from some very fine sand particles in the clay, so perhaps it would benefit from a little frit? I am still learning and also very interested to learn how the various materials work together in a glaze.  I am aware that this glaze would definitely not be a glaze to use on domestic ware. I was looking for something like this for sculptural pieces and liked the idea of the metallic finish, although def not fond of it being rough. I will take your advise on substituting some of the manganese for those other materials to see what happens.

Sounds interesting Brian. I do have some nice matte bases now that I could do that with instead of  testing a hundred and one glaze recipes to find new and exciting ones. I am fairly new (2yrs) with making and testing glazes and it's like seeing a good cooking recipe, I think 'oh, I will try that'. When really, once I have found some reliable bases, I should stick with those and just do some simple line blends with colourants to see what I come up with.

I don't know if am as patient as you though to do the whole ball milling thing with a glaze? I would be interested to see a glaze that you have done that with though. Sounds very interesting. Would love to see some photos of your work Brian. Have a great week.
