– Use light colored bottles. The swirl pattern will not show through dark glass.
– Fuse flat first. I got the best results by fusing the bottles flat before slumping them in the mold.
– Slump at higher temperature. I slumped at 1275 degrees F which is about 50 degrees higher then my normal slump temperature in my Skutt kiln.
– Hold longer. I held at slump temperature for 45 minutes.
I love the way the light shines through and casts the swirl pattern on the table. Hope to have a few of these available for sale at the Holiday Market I will be participating in this fall.
