Hello all : ) I just bought some cobalt oxide, I'd like to paint it directly on some leather hard stoneware vessels before bisque. Can I ask if anyone knows which percentage of cobalt to amount of water should I use for best results? Thank you!

Hi there, I'm pretty new to glazing and looking for help. I've always been in love with Lucie ries work and have been trying to create a beautiful black glaze of hers made up of equal parts manganese dioxide and red clay. I'm not even sure you can call that a glaze which maybe why I'm having problems with running. The glaze looks beautiful but it runs! Is there anything I can do to stabilise the glaze while keeping the beautiful finish. I am firing it over earthstone original clay in an electric kiln to 1230. Up to 600 at 60/hr then at 100/hr up to 1230. Does anyone have any suggestions to help? I also wondered if anyone might know of a way of making this food safe? Can you layer a clear glaze over it? Appreciate your advice.

It's me again. Some advise please. My teacher suggested I use Indian ink to emphasize crackels in a glazed piece. If I did that would I have to refire? If I used say cobalt or black iron oxide instead of the ink, which would give a better result? The pot in question is

Hi all my local hardware store sells a product called Black Oxide which is used to colour cement. Has anyone tried this is a glaze recipe? I dont know the chemical formula as their product website does not give that information, only that it is derived from anthracite and coal. So I dont know if it can be used for glaze? Can anyone help?

Just starting to do pottery at home. Have inherited many bags (40+) of cone 4-6 glazes, stains and oxides and I am overwhelmed by all of it. I have done some pottery before but in a school where all the material was premixed. I know how to mix powdered glaze with water, no problem, but don't know how to mix the stains and oxides. Plus, I don't know where to start. Do I start trying out just one glaze or do I prepare small batches and do a series of test tiles?
