This 5-day intensive focuses on exploring color application, surface texture, and basic shaping in flameworked glass. Students will build a personal library of forms and textured components through a series of guided demos and exercises, then assemble those elements into a final object or objects of their choice.
Emphasis is placed on experimentation, intentional design, and developing confidence with both color and basic shaping on the torch. Techniques covered include color prep, turning rods into tube, layering, experimenting with texture, shaping hollow tube, and basic assembly. This course is designed for students looking to strengthen their understanding working with boro and expanding their ability to translate visual ideas into form.
Experience is strongly recommended. Students should ideally have prior experience working with hollow borosilicate. Beginners are welcome, but should be prepared for a fast-paced environment with a lot of information, demos, and new techniques introduced throughout the week. This is an immersive, technique-rich class designed to challenge and expand your current skill set.
