      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.

        The Kilncast Box

        Who said, “ Kilncast Boxes”? Nathan has been making, and teaching people how to make, kilncast glass boxes for more than a decade now. At OnGrade Studio our boxes range from 2” x 2” x 3” to 12” x 16” x 5” and can be made of frit, billet, slabs or even Vitrigraph murrine. Some are extremely thin walled, while others are pretty hefty. In 2012 we actually made 100 identical boxes for a client!
        location_on OnGrade Studio - ZOOM alarm 1 PM - 4 PM
        Over four online sessions Nathan will introduce you to the moldmaking methods he uses and demonstrate casting multiple forms of glass into the (mostly) reusable mold system. After things are cool, we’ll head into the coldshop and learn the steps necessary to professionally finish your casting.

        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 Mold + Materials Kit will be available for purchase two weeks prior to the workshop

          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.
