Studio Equipment for Sale - Calistoga, CA

The Story of the Studio

This professional glass studio in Calistoga, California, was born out of a shared dream between my husband, Mark, and me. Together, we designed and built this space to the highest standards, selecting top-tier Spiral Arts equipment and custom-engineered systems to support a lifetime of artistic production.

Sadly, Mark passed away shortly after the studio was completed. The most of Hotshop equipment was in operation for only six months. It was professionally installed, meticulously maintained, and remains in like-new condition.

My goal is to see this beautiful equipment move on to a home where it can continue to foster creativity, education, and the craft of glassmaking. Whether you are a university looking to upgrade your facility or a professional artist establishing a new shop, this equipment represents a rare opportunity to acquire a complete, "plug-and-play" professional system of the highest caliber.
