Seattle Pottery Supply offers firing services for our local potters.

We are proud to provide space to our community who might not have access to a kiln otherwise. 

Our Services: 

We offer three types of oxidized firings: 

• ∆05 Bisque
• ∆05 Low-fire glaze
• ∆5 Midrange glaze

(Cones outside of our regular firings are available upon request and are subject to additional fees.)

No appointment required! All you need to do is carefully box up your work with some padding and bring your pieces in during our retail hours.

Pricing 

Pricing is based on the amount of space you take up within the kiln. 

Firing is a minimum of $12. This pays for roughly 12”L x 12”W x 4”H. We use this as a general guide to scale your price. If your pieces exceed that area, the cost increases in roughly $2 increments. Costs generally go up in glaze firings since we cannot place items as close together as a bisque firing.

SPS has several kilns, the largest of which can accommodate a form that is up to 25” tall and 28” wide. 

(Please call ahead with dimensions if your piece is large).

Additional Charges

There are additional charges for:

•  Any damage to our shelves from running glazes or stuck pieces
• Special handling (multiple small pieces/very large pieces)
• Stilting or hanging*
• Extended kiln pre-heat time
• Rush —requires communication with techs before drop off—

These charges are at the discretion of our kiln techs and are non-negotiable. 

If you fire with us you must accept the responsibility of extra charges. We try our very best to be fair and conscious of cost when applying extra charges.

Firing Requirements

Pieces for bisque must be completely bone dry

• Sculptural and/or very fragile work may be brought in leatherhard to help with transportation.

Pieces must not include foreign objects. 

• Includes but is not limited to wood, paper/newspaper, metal (unless it is verified high temperature wire), plants, feathers, or hair. 

You must know the name of the clay you are working with. 

• If you do not know, we reserve the right to refuse ∆5 midrange glaze firing services.

It is recommended that you bring in your own kiln accessories if you require a special arrangement for firing. This includes but is not limited to: 

• Stilts
• Cookies
• Bead Bar
• Tile Setters

When will my pieces be ready to pick up? 

We will email you when your pieces are fired and ready to take home (please check your spam folder as sometimes our emails get sent there). 

We appreciate your patience! Please wait to call/email us until it has been 1-2 days beyond our expected turnaround time. Expected turnaround time is posted at the retail counter upon drop off.

Turnaround time varies, depending on demand, especially leading up to and during winter holidays. Waits can be as long as 4-5 weeks during our peak seasons. Please plan accordingly.

Our small and dedicated team of kiln techs work hard to keep the process rolling, but our first and highest priority is always a safe and successful firing. 

Final pricing will be provided at pick-up and cannot be given before items have been fired. 

*Notes on stilting / ornaments:

• We only stilt at low fire. The only exception is small and light pieces for midrange. 
• We can fire hanging pieces at either temperature but they must have holes large enough to fit bead bar through. Alternatively they must contain well connected loops of verified high-temp wire that are large enough for bead bar. The holes must be unglazed. The pieces should not be too heavy, especially at midrange, as the metal bead bar gets soft during the firing.
