It may not be new but came to me in the middle of the night and had to try it yesterday.
These 9mm Czech glass donuts make easy loops for off-mandrel work. I strung a bunch of them on 1/8" mandrel and keep them warm in the kiln. Slip one off the mandrel using tweezers when the glass is ready for loop. To be safe, I did use Czech ivory. I will try this on other COE104 today.
