Description

Imperfections are a natural part of pottery, and many of these only manifest after a pot has been either bisque or glaze fired.

But you don’t need to throw a pot away just because of a minor imperfection!

In this episode, I talk about four very common imperfections in fired pottery and simple ways to fix them: 

✔️Hairline cracks appearing in pieces of pottery after the bisque firing, in pieces of pottery that have been joined together

✔️A rough surface after a pot has been glaze-fired, created by a too-thin layer of ash glaze, e.g on the rim of a mug. 

✔️A rough surface on the base of a pot caused by tiny pieces of kiln shelf sticking to it after the glaze firing. 

✔️Bubbles in a glaze that become sharp once a pot has cooled after being glaze-fired.
