Glazing … it tends to be the bane of most ceramic artist’s existence.
Why? Well, where to start?
I suppose I could begin with sharing that the glazing process is a chemical reaction activated by the heat of the kiln. Before firing glazes all tend to look kind of pinkish, brownish, white-ish, red-ish or sometimes grey-ish, but certainly never the color they will be after firing. Its enough to drive a person batty imagining the “correct” color.
Catch those quotes in my last statement? Chemical reactions also mean that glazes don’t necessarily combine based on the color wheel or logic. My favorite example of this is a beautiful turquoise matte glaze that turns maroon when a clear is applied over it instead of a shiny turquoise color.
I could go on about glaze application thickness and application methods, but I fear I’m digressing from that drip I mentioned. All of that activating heat also means that glaze doesn’t like to stay where you put it. Instead glaze tends to run and pool. This can be extremely helpful as well as frustrating.
You see, glaze that runs can run right off of the pot onto the kiln shelf fusing your pot to the shelf. So, that intriguing little drip when it happens is something that gets ceramic artists very excited. This is especially true when that lovely drip stops just before disaster and instead leaves behind a focal point on your piece.
