      Three Wedges

      Remember 2005? Nathan was one member of the team of Bullseye Glass Co. technicians working with internationally known ceramic artist Jun Kaneko on a massive kilnformed glass project.  In the years that followed Nathan helped develop curriculum in kiln glass that built upon the discoveries made during the Kaneko Factory Exchange. Fifteen years later, the original methods are still in use at OnGrade Studio and continue to evolve..
      location_on OnGrade Studio - ZOOM access_time 10AM - 3 PM
      When glass is exposed to adequate heat work in the kiln, it seeks a thickness of 6mm. This principle, in combination with simple engineering ranging from stacking glass to making ramps and placing glass on an incline can be exploited in a variety of ways-many of which are still relatively unexplored at this point in the history of kiln glass. 
      Join Nathan via Zoom to consider how glass moves and how we can use flow to our advantage. Principles of flow, deformation and displacement will be exploited. Each of three projects will result in a sculptural, thick wedge that demonstrates flow within a larger volume of glass.  Project sizes will range from 6” x 8 X 1.5” to 4” x 3” x 1” making them appropriate for a wide variety of kiln sizes.
      Coldworking is an integral part of working with flow. Post firing demonstrations will take place in the coldshop.  Attendees will find that the finishing skills learned in this class are applicable to all types of kiln glass projects.There will be plenty of time for questions and group discussion and an informative handout will be provided.
      While we don’t see this as a 
      follow-along type lesson, a customizable Mold + Materials Kit will be available for purchase.

        Rubber Molds for Lost Wax Kilncasting

        Learn to reproduce just about any found object in kilnglass through the magic of Lost Wax Kilncasting. In this online workshop students will follow every step of the process as Nathan makes a rubber mold of a handcarved wooden beast into which hot wax can be poured. From there he'll demonstrate how to make a custom kilncasting mold and ultimately how to fire, divest, and finish the glass replica. All content will be presented LIVE via Zoom and attendees will receive a recording.
        location_on OnGrade Studio - ZOOM access_time 10am - 130pm
        Lost wax kiln-casting has an unfair reputation of being complex, messy, risky, even dangerous! The truth is that some (not all) of those descriptions are true….But that’s what makes it great!

        Nathan has been using these methods in a confined space for years. Join him in this four session workshop to learn how to exploit the benefits of lost wax kiln-casting, cleanly, in a home studio.

        This workshop focuses on kiln-casting solid, three dimensional animal figurines using the lost wax approach to kilncasting. Gaffer Glass (lead crystal) will be used.

        Daily activities will include demonstrations, lectures and plenty of time for questions and discussion.

        All skill levels are welcome but those new to working with their hands should be prepared to be challenged.


        Coldworking is an integral part of finishing a kiln cast object. Post firing demonstrations will take place in the coldshop and an informative handout will be provided.
        While we don’t see this as a 
        follow-along type lesson, attendees will receive a recording of all sessions and Nathan can be scheduled for followup questions/help.
