I am having a friend save me some guitar strings to experiment with firing a piece that is wrapped with them to see what kind of effect the melting/burning of the strings has on the clay and glaze. I swear I have heard of this being done before, but I am struggling to find anything on it via Google. Has anyone experimented with guitar strings in their firings before? I'm wondering if I'm wasting my time or if it could have some cool results. Thanks in advance!
