After trying several cone 6 matte glaze recipes, I've decided to narrow it down to this one that I got off of the Digitalfire website
I'm loving the glaze. It mixes well and goes on very easily. It also has great colour response. I'm currently looking for a dark, slate gray. My first tests gave me this:
The surface is incredible! There is so much depth to the color, it's fantastic! HOWEVER, see those runs? The next few tests made a mess of my kiln shelf. NOT GOOD.
Soooooooo, a few more tests:
The first picture, confusingly marked '2', is the above mentioned glaze recipe with twice the colorants as the original test piece. I was hoping that if the glaze was darker, I could apply it thinner and get the effect I was looking for. Aparently, I was wrong. (surprise, surprise!) The glaze has a distinctly green tinge to it. The second picture is that original recipe, from the first test above. I wanted to see if I could repeat the results. The answer is sort of. Oh boy. More testing in my future...As you can see, I still have the problem of the running, and in defense of the glaze, I AM overfiring it by about a cone.
Soooo, back to the testing. I can increase the alumina in the glaze to help with the running but that will also make the glaze more matte, which is not what I want. If I want to keep the current matteness then I could increase the silica along with the alumina which would also raise the firing temp a bit, which would probably help me out anyways, so that's most likely the route I'll go.
As for the feltware, it's coming.
I'm really enjoying felting. I've been working on a series of tiles:
This roving I bought at Romni Wools in Toronto.This particular colour, eggplant, came in a bag with red and black roving. I LOVE this color. And ordered more along with some complimentary colors from A Childs Dream
These tiles will look very different by the time I'm done with them. I'll just have to be patient and check the mail.
nice glaze... wondering if it would be translucent if it was applied thinner? love your pots shown on etsy
ReplyDeleteThere is an opacifier that was added to this glaze (titanium dioxide, 5%). Without it, the glaze is sort of translucent. It's a really nice glaze to use, the slurry has lots of epk in it so it goes on really nicely!
ReplyDeleteYou don't happen to still have this glaze's recipe, do you? Or know where I can find it 5 years after your experimenting?
ReplyDeleteHello, may I know what and how much colorants/ modifiers did you add to this beautiful glaze? Thank you!
