One Day Zircar Casting with Brooke Hamling

In this one day workshop students will get an introduction to hot casting glass using Zircar Mold Mix molds.  Pouring hot glass into molds in the hot shop allows artists to create unique solid glass objects.  Zircar Mold Mix 6 is a high temperature ceramic mold material used to make light-weight, strong, reusable mold for glass casting and blowing.  During this workshop students will make several reusable molds using Zircar Mold Mix 6.  These molds will be made over pre-made floral and botanical wax positives. After the molds have dried the students will learn to cast glass into the molds in the hot shop.

What to Expect: During this workshop students will make several palm sized floral and botanical molds using Zircar Mold Mix 6. These molds will be built up around pre-made wax positives. After these molds are allowed to dry during a brief lunch break, the class will move to the hot shop and begin casting hot glass into the molds.  These molds will be open-faced and are generally reusable. The students can expect to leave the session with the skills to make a Zircar mold,  their reusable molds, and eventually the glass objects they cast during the session. The class will include demonstrations but students will make their own molds and participate in casting the glass.

This is going to be a low stress - high instructor input introduction to the hot glass studio. Everyone will hopefully get to walk away with multiple pieces that they will feel they had a hand in creating AND be inspired to come back and learn more about glass. Glass in its molten state is 2000 degrees. The hot shop is a loud studio, and can get quite warm. Read more about how to prepare for class on our Registration Info page. 

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

Pick-up: The glass needs to cool down over several nights, 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. Health and safety guidelines will be emailed to you upon registration.
