(Hello new here
)..I've been trying to make leaf headpins using a leaf masher, and find there is often a crack formed just where the wire goes into the glass..
I've been slowly backing them out of the flame and putting them straight into cooling bubbles to batch anneal later.. Is this what is causing the cracking? (I didn't want to have the kiln blazing away all the time.. ) Is the copper wire conducting cold into the hot bead? Does anyone have any suggestions as to a way to make them without them cracking?
