Seattle Pottery Supply Reviews 

My order arrived quickly and in tact. 24 pounds of clay is no joke to ship. I’m happy and look forward to trying my new clay!

Ordering was so simple and my order was shipped right away. A really great experience.

I LOVE MY KILN!
Disclaimer - this is my first kiln, so I have nothing to compare it to.
- The kiln is very well made without being overly complicated. It is easy to disassemble and reassemble to move. The components seem to be high quality. And it seems to be easy to maintain myself, which is important because I’m in Texas.
- The interior size fits more pottery than I expected. I got the recommended shelf kit - does what it is supposed to do and has just the right amount of pieces to meet my needs. I may opt for 2 additional half shelves in the future.
- The standard specs work with my existing electrical setup, including the outlet, so I didn’t have to have any electrical work done.
- I ordered a custom length power cord. It is a behemoth… very thick and sturdy.
- The Bartlett Genesis Spark touchscreen controller is excellent. It is easy to use, but also seems to be very versatile, allowing unlimited customization of firing programs. My only complaint is the online app. It is quite rudimentary and not particularly helpful. You can get the free limited version, or pay ~$20/year so it will send you a text or push notification if an error code pops up, or when firing is complete. But, hey, it’s still a great product. I can check the temp without having to go to the very hot garage.
- SPS has been great! They answered all my newbie questions, and the videos on their website are quite helpful. This all made me feel confident that I was not getting in over my head. Also, the packing strategy they use for shipping is incredible. I’ve never seen anything so well protected for a cross-country trip. The kiln arrived in pristine condition.

I’ve run several quick bisque firings and two cone 6 glaze firings so far. Everything is working exactly as it should.

Sidenote - someone told me they don’t fire in the summer in Texas because they don’t want the heat to ruin their controller. The first quick cone 04 firing in July did end up with the board getting almost to the heat tolerance limit. After that, I put a fan 16 inches away aimed directly at the controller box. That lowered the max board temperature over 50 degrees. No more worrying.

Great shop, great staff! My new favorite place!

Great selection with helpful info on expected behavior of glazes. Arrived very quickly compared with some other vendors. Seattle Pottery Supply is now my go-to shop.

Fast shipping and excellent packaging!
The website was easy to navigate.

Seattle had what I needed and shipped it uber fast. I price checked and they are competitive, no need to go anywhere else.

My wife has been creating hand thrown pottery for almost 50 years. Matsui Hand Thrown Pottery has relied on SPS exclusively and have never been disappointed.

Information on the website made ordering products a breeze. Staff was very helpful when I picked up the order the next day.

Fast and accurate order delivery.
Good prices, and nice people.

I’ve loved the clay I’ve ordered. They processed my order fast and it was delivered fast as well. I’ll definitely be ordering again in the future!

I received the discount as promised The shipping for the clay was not too expensive and was delivered within a week or so. Thanks, I have not used the clay yet, but the write-up about it look good.

Clay arrived on time. The boxes were intact.

I absolutely love the gray speckled clay!! Easy to work with and fires beautifully!!

The knowledge and expertise of the staff is excellent. I have a very old equipment, which has been in storage for decades. Getting those older mechanisms back into working condition was huge problem for me which advice from SPS was so helpful. I am still needing to update my stuff, so I will be going back, I am sure, for more advice from time to time.
