Kiln Casting Part 1 with Catarina Cubelo

The focus of this class is to learn the basics for casting an object in glass. We will cover a range of topics, including simple mold recipes, wax-working techniques, kiln requirements, kiln-firing schedules, and techniques ranging from basic glass cutting to sand-blasting and cold-working. Part 1 will cover Open Casting and Part 2 will cover closed casting. Sign up for one or both!

Part 1 will cover Open Casting

In Part One (4 weeks) you will be learning the basics of casting objects in glass using the open-face technique. The process involves creating a relief sculpture by investing a model in a refractory mold material. Once the mold is made, the model is removed, leaving a void to be filled with glass. The course will be structured first with an introduction to the technique and a demonstration of how to make plaster and refractory molds. Once you complete a simple casting exercise, we will discuss the results and you will be able to make a casting from a clay model of your design or learn how to cast from an existing object. You will have time to craft your second object, fire it, and cast it in glass. Finally, you will learn basic cold-working

techniques to finish your piece and we will discuss simple firing schedules. You will be able to cast at least 2 pieces and maybe 3 in total depending on the size of your pieces. The maximum size for pieces is 8 inches (L)x 3 inches (height) No prior experience is required.

Part 2 will be held on Thursdays, May 15th – June 5th, 6-9pm. This session will focus on Closed Casting and making drinking cups. Read more HERE.

What to Expect: Participants can expect to leave with 6 finished objects plus sample tiles, this varies depending on the participant’s choices and size of the piece. Read more about how to prepare for class on our Registration Info page.

Kilnforming work involves a mix of seated and standing activities, including preparing glass pieces for firing, and loading and unloading the kiln. A particulate respirator mask is required when working with fine glass powders or unloading kilns after firing and would be provided for you if needed. Handling glass and tools may require a certain level of dexterity. To learn more about accessibility the Accessibility page on our website.

Eligibility: No previous experience required. Open to ages 14 and up.

Pick-up: The glass needs to be fused in the kiln and cool down overnight, so the students will have to return to UrbanGlass once notified to pick up their work.

This is an in-person class taking place on-site at UrbanGlass.
