Thank you so much for your input MDM, it's much appreciated.

Your advice on marking the mug not food safe makes sense. I just went and wrote that on the bottom after reading your comment. :)

Unfortunately being a community kiln i have no control over the firing. I go to each weekly class, glaze a mug or two, leave it there and hope it's been fired and comes out OK the following week when i'm there. My biggest issue has been with the green glaze, and the crazing on the recent brown mug i think has more to do with temperature fluctuations. Melbourne winters are quite crazy. Cold at night and then quite pleasant during the day. The slip i've been using has been fine for all the other mugs i've glazed so i'm not sure what's going on. I think it is the combinations of glazes i'm using. The interior and exterior glazes might be the same brand but there is obviously an issue with them reacting to one another after they've been fired. A tension issue i believe it is.

I'm very new to this and have learnt, as i've been told and read, that this is not an exact science and you cannot guarantee the outcome that you are hoping for will work. It's just frustrating spending so much time making and glazing a mug to have these things happen.

Thanks again for your comment.
