Speedball Mid-Fire Smoke Glaze

ProKilnSupply is not a general store. We specialize in pottery kilns and ceramic firing equipment. It is all we do, so we can help you choose the right kiln, power setup, and accessories with confidence. We work directly with trusted U.S. manufacturers to provide 100% authentic products, expert guidance, and custom options when available. Most orders ship free, and we typically do not charge sales tax except in Utah. That often saves customers significantly compared to other sellers. Financing may be available for qualified buyers.

Plus, our Best Price Guarantee means if you find the exact same product listed for less online, we will match it.

We are an active, U.S.registered business that fulfills orders every week for customers nationwide. After you place your order, you will receive an immediate confirmation email and we will begin processing right away. As soon as your order ships, we will email tracking details so you can follow delivery updates.

For made to order items, production begins after your order is processed and we will keep you updated along the way until it ships. If you ever have questions, our team is easy to reach by phone, email, or live chat before and after your purchase.
