  2. Purchase shares for the firing. Shares are $55 each. Buy as many as you’d like.
    — Each share is 1/2 Cubic Foot. (this is a 6” x 12” x 12” space.)
    — Each share comes with 2 hours of glazing and wadding at RCS during designated hours

  3. Make your artwork for the kiln!

  4. Schedule Check-in and Glazing time

    — Each participant must schedule a 15-minute Check-in for measuring your pots/ shares.
    — Glazing and Check-in must be scheduled (link on Clay Q&A). It is ideal to Check-in before glazing your pots to avoid chipping your glaze. You are also welcome to wax, glaze, or prepare at home.

    Please fill the space you purchase! No more no less. If you bring extra, please be ready to purchase more space in the kiln if it is available. If you bring extra, these need to be labeled as such. If there is extra room in the kiln we will add them at the end.

WAD SQUAD = The Wad Squad helps with loading and unloading. It is physical work! We carefully place pots and heavy shelves, we unload, we clean up, we scrap shelves, and make it all happen. If you are interested in helping with loading, unloading,g and all the work that goes into it, add your name to the list here. (More Info)

Loading the kiln

Loading Day! Deb will load the soda kiln with the RCS Wad Squad (designated ahead of time via the form at the top of this page).

FIRING the KILN

The kiln is fired overnight after loading. In the morning the kiln will be near body reduction. This is just an estimate and will be revealed as we fire. The beginning of the firing is slow and participants are invited to help introduce soda into the kiln! The soda solution is added to the kiln at peak temperature (hopefully around 1pm-3pm on firing day > this is TBD).

Spraying in soda solution

Firing the kiln:
Firing the kiln will take 12+ hours. It is checked every 30-60 minutes. The results will be logged online so you can follow along if you’d like to.

Introducing the Soda Solution:
To participate this portion of the workshop, you must wear long, non-flammable pants (blue jeans), closed-toed shoes (preferably a boot), and your hair up and back. You will be around extreme heat. You will consistently be taking off and putting on gloves.

Sharing and Pick-up

Unloading and cleaning up:
Deb & the RCS Wad Squad will unload and place all the artwork on tables. The workshop participants are welcome to come see all the results at the designated time (see times at the top of the page).

Be sure to bring plenty of packing material, as well as, boxes and/or totes to nest your finished pieces into after share time. And now, The workshop is complete!
