You all might remember awhile back I asked about firing a lidded box. I asked about alumina and several people were very helpful in suggesting ways to fire the box with the lid on and not have it stick. Well I think I did something wrong... I mixed 2 teaspoons of alumina with 4 oz of liquid ceramics wax. I then brushed this on the bottom edge of the lid and the top edge of the box including the flange. I let that dry then glazed the box with the lid on and fired it to ^6. Well on a happy note the lid did not stick at all! On a sad note in several spots it almost looks like the wax and alumina mix melted and ran down the side of the box leaving a permanent dull white dusty mark. Boo hoo so what did I do wrong? Did I use too much of it? Should I only apply it to one edge not both? Did I use the wrong kind of wax to mix with the alumina? Can I use something like steel wool to sand as much of this mark off as possible them reglaze and refire it? I'm basically looking at it as a learning experience at this point so am willing to try some different things to see what happens. I have another lidded box that I am not going to glaze fire right away until I feel a bit more confident in its survival or at worst I'll fire the lid and the bottom separate and hope they still fit together afterwards. So any suggestions anyone? Terry
