TThis is an intermediate to advanced class on glass casting techniques intended for students with previous mold making and glass experience. Over the course of eight weeks we will cast as much glass as possible. Students are encouraged to explore and experiment with ideas. We will have a sand casting project and explore cold working techniques. Although this class has a similar layout as the beginning class my intention is to go into greater detail and scale up projects. Class size will be smaller and therefore students will be able to make more castings and larger pieces.
The weekly class schedules listed below is flexible and will change with the given circumstances. Some factors, which often change the class schedule, are availability of furnaces and kilns in regards to the other classes. Because the work we will be doing is larger and requires longer annealing schedules we will have to allow for changes in the weekly projects here given. That being said this is a rough guide and basically covers all the topics I will cover. Please email me with any questions or concerns. At

Estimated cost of supplies $40.00 - $100.00 this largely depends on the type and amount of glass used.

week 1 Introductions and Overview

We will jump right into first project open face casting. You should try and come to class with a ready to go model. We will be making investment molds and placing them in to the kiln with a firing schedule. Please see Open Face proj. notes
