Never look down at a warming mandrel (glass rod warming in the other) and think...hmmm that mandrel looks bent....and then put down the glass and try to bend back the mandrel straight! The result will be burnt on bead release on your thumb and 2 neighboring fingers! I did this and had a groove burned in my 3 fingers for 3 days! OUCHIE!!!
Dum de dum dum......DUMMMMMMMMMMMMMMMMMMMM!!!!
