This vessel is in green soft glass. When I first started this vessel, I annealed it in vermiculite and found extensive cracks when I took it out. I kept it on the mandrel and put it into a cold kiln to see if I could reheat and heal the cracks. I brought the kiln up to 537 degrees centigrade, took out the mandrel and reworked the vessel plus tinkered with the handles and added the darker green blobs.
Finally I reblew a little to round out the bulb. This vessel is 40mm high by 36mm wide from handle to handle.
