Kilns - Olympic HB86P Vitrigraph Kiln

Olympic HB86P Vitrigraph Glass Kiln

Olympic's Hot Box 86P is a vitrigraph kiln mounted on an adjustable stand so it is easy to reach and move out of the way when not in use!  The lid removes easily for easy top-loading access.   The solid top allows this kiln to achieve temperatures up to 2350°F.  Since the lid is removable, it allows extra sections to be optionally added.  Add a blank collar or bead collar (with a door) that will add 4.5" depth to your kiln (but does reduce the max temperature to 2000°F.

The HB86P Vitrigraph comes with 2 floors, 1 fiber & 1 cordierite - both floors with holes for stringers to flow through. A brick floor for firing the kiln during regular use slumping, fusing, jewelry making, testing, etc. can be purchased separately.
