i did on monday. this past saturday i spent almost 4 hours on a marble...the biggest i've made to date at 2.1"
well monday i pulled it out of the case to show someone at work, and i dropped it on the concrete floor
now there's a huge fleabite right smack dab in the center of the lens. i can fix it, but having to warm up a marble that big in the kiln is a risky proposition.
