Extremely Pricy Raw Materials I was recently charged $141.03 for 10lbs of Bone ash and $67.59 for 50lbs of Nepheline Syenite. This is outrageous pricing. On a whim, I checked the price from a local competitor and the price was half of what I was charged. I felt cheated!! My recommendation for people going to SPS for raw materials is to check pricing before committing to purchasing. My high price experience was limited to raw materials and I plan to warn the schools where I teach at to be vary of their price gouging.

Arrived in good time The Klamath Yellow clay arrived forthwith. I have been using it a lot, and I really like how easily it re-wets and handles in general. I'll undoubtedly need more.

Best in all aspects So fast, so cheap and top quality at the same time, unbelievable.
