Should have known from experience that first impressions doesn’t mean a thing when it comes to producing these bubble blocks. Thinking that having one side of the mould holder wider to allow packing, would have been enough to cater for extraction. It was a tedious and messy operation as movement during firing had given the opportunity for some of the mass of glass to leak. Was thinking, here we go, three days down the tube. After cold working the piece is looking fine.
To make life easier for now I split one side and tie wired it back to correct width. When the stack above comes out in three days It will just be a case of cutting wire and spreading mould holder for easy extraction. That’s the plan anyway. Can’t wait to see how all the layers of black will look.
