USNice glazes. Nice glazes. I especially appreciate the descriptions of how the glaze reacts at mid and high fire. Glazes were carefully packed and boxed.

USEverything arrived promptly and well… Everything arrived promptly and well packaged... Only problem was when I was purchasing the stilts I wasn't aware that the postage was going to cost more than the product....I tried and tried to cancel the order but couldn't figure that out...I received them and am very happy...just cost more than I thought :)

USExtremely 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.
