Online Ceramic Course Policies Materials and Firing

Clay is available to be purchased from the Umbrella through our website, and picked up through our curbside service program available Tuesdays and Thursdays. The cost is $35 per 25lbs and includes all firings. Studio glazes will not be available until we can safely re-open in phase 3 of the Massachusetts re-opening plan. Members are welcome to purchase cone 6 commercial glazes and have their work glaze fired if they don’t want to wait. Please Read all of the Details outlined in our Curbside Service Plan before Coming to the Studio. 

If you purchased clay from elsewhere and would like it to be fired at the Umbrella...

  • Your clay must be rated for our firing temperature, Cone 6 or hotter. We Highly recommend using the studio clay bodies if you intend on using studio glazes in the future. Please email if you have any questions.
  • Works can be transported to the Umbrella studio to be fired during our curbside drop off hours (Tue & Thur 10am-4pm). 
  • Clay purchased from outside vendors will have an additional $1 per pound fee to cover the cost of one bisque and one glaze firing (re-firing glaze has an additional 50 cent per pound cost). You may purchase commercial glazes or wait until the studio is back open for scheduled glaze time access. If you plan on having your works fired at the Umbrella when we are ready, please drop off cash or a check when you drop off your wares. In order to keep the systems simple and fluid, we ask that you pay for 25lbs of clay at a time (one bag).


Entrance to the Umbrella’s physical studio is off limits, but we are open for drop off and pick Tuesdays and Thursdays. Once we enter phase 3 of the re-opening plan, we will access our options to have students enter the building to glaze. Due to the added time of cleaning and scheduling, we are anticipating a 3 week firing turn around. Although works will be stored for 1 month after they have come out of the kiln, we are encouraging everybody to pick up their wares as soon as possible and try to reduce the amount of bisque ware we need to store.
