I love a firing with lots of new glazes (if it's working). For days after you start to see it in different ways. Sometimes a glaze that you first thought was awful turns out to be a new favourite. I think this can happen because you expected it to look a certain way, and when you open the kiln door for that first look; it does not always turn out the way you expected. Probably why I keep making new glazes. And it's also probably why I have not bored of ceramics.
