I ordered 5 gallons of SP930 Swan Porcelain Slip $74, but the product I received was extremely watery with zero clay sediment at the bottom. More importantly, it is highly caustic. After briefly checking the consistency with my bare hands, it caused a chemical burn sensation and left visible pitted marks around my pores. This is not normal slip behavior. Be very careful with this batch—it feels more like a bucket of harsh chemicals than pottery slip. Highly disappointed.

Ordering on line has its challenges but we like the way your site shows us what you have and how to order it. Normally order on Amazon for free shipping but what we needed was not available.

Seattle pottery has everything you need and then some. Prices are great, if something is out of stock they’ll let you know as soon as the item is restocked and shipping/delivery was quick. I highly recommend them.

Great home kiln.

After seeing several SPS videos about the 184 electric kiln and how it's perfect for the home studio, I went ahead and ordered one. The sales associate who helped me on the phone was knowledgeable and let me know there would be some lead time because it would be built after I ordered it. We live in Southern Oregon and we had it shipped. They kept me posted as to when they were shipping it. The videos on the website and the information packet are very helpful. I have the Genesis Spark controller on my kiln and it is so easy to use. It keeps track of every time I fire and if there were any error codes.

a great supplier for potters

I appreciate the fast service, the detailed information on your website about the products and the protective packing you give the products for safe shipment. I am a novice potter still learning about the differences in kiln temperatures and glaze reactions.Your website is so helpful.

SPS The Beat

SPS is top notch for all my pottery needs, from tools to glazes to firing services. I couldn't be happier to have found such a great one-stop shop with kind, thoughtful, and knowledgeable people!

My first kiln

The great customer service is what takes me back to Seattle pottery supply. They explain everything very detailed, especially when it comes to working with kiln. It was my first experience and little anxious how to operate the kiln. I also bought my first Shimpoo pottery wheel from SPS. Same experience. Highly recommend.
