In this webinar, Nathan presents the methods and materials necessary to make one of his newest designs. He will demonstrate how to cut circles and quickly move on to rings of sheet glass. To make it even more interesting, Nathan will show you how he cuts rings without the need for a relief cut! From there he will move on to making a blank that will ultimately go through three firings before turning into an amazing 9.5” diameter dropout vessel.
Post firing, Nathan will take you into the cold shop to introduce you to a new, comfortable, approach to rim removal before a bit of coldworking to resolve the rim. When all is said and done, you will have an amazing Inside Out Flow Vessel!
Note: The main project is 9.5” diameter and requires a 16” kiln shelf. The dropout will be 4” deep, which requires a 10” deep kiln. Smaller and shorter versions of the project will also be presented. A sandblaster and the ability to coldwork are integral parts of this process.
