Stuff for bisque firing in my new kiln

Slip cast mugs/cups. Relief pattern made by slip casting truncated cone wrapped in textured paper. I had lots of trouble making the plaster casts because my moulds kept breaking. Have now overcome that with a silicon mould in the shap of a large cup which I then cast into. Mould making is hard work, so much time is necessary to make your mould right. Otherwise you end up with a useless mould which replicates the errors that you made. Grrrr....
These mugs are not prefectly symitrical which I like. I don't often find work that looks like it came out of China appealing. Theres no emotion in the form, its souless. Unfortunately we have come accustom to these mass produced reproductions. I recommend taking the time to hold something in your hand that was made by hand by someone. Its a nice sensation. I recommend it. Even better if the object they have made is also nice or appealing.
These are some little coasters I am making for my sister. They are also doubling up as test tiles at the moment until I figure out the shape I am trying to get...
I am hoping to put blue green glases applied glaze on glaze.

Glaze trials and tribulations

Recently have been messing around with new glazes. I am looking for oxidation recipes for my new kiln.
This is a random glaze. Different materials were picked out of a hat and different quanities were picked out out a hat. Most of the time they don't work, and the exercise is to make it work. These ones did work in Oxidation at Cone 10. The reduction tests are still to come and they probably won't work because it has lots of zinc and zinc doesn't do reduction. This recipe has barium in it so no good for functional wear. Will look to replace this material with something else to make it safer.

This is the glaze analysis for my random glaze

Green Apple glaze found in book in a line blend. I thought this glaze would be more matt. I was fired at Cone 10 oxidation. Reduction results are still to come but they should work too.

Glaze on glaze prefired tests on Keanes 5B. This is to be fired in reduction.
