Love the Concept

I absolutely loved the idea of the liposome capsule and delivery system with this foundation. I became a Jane Iredale fan with the starter kit in creamy, and have purchased everything from the Mystikol set, the 'smoke gets in your eyes' shadow set, to each color of the lip fixation product, and have been thrilled. I am wondering whether my unsatisfactory experience with the liquid minerals foundation is an unusual one, or whether others have experienced a gritty texture that almost peels off the skin after a short period of time. I tried pumping more of the product out of the container, to the point I had wasted a significant amount, and yes, indeed, discovered a slightly creamier product. However, the next time I used it, there was the gritty stuff again! SInce I am a huge fan of the line in general, and really want to have the results others have spoken about in their reviews of the liquid foundation, I hope that I simply got a "bad batch'" similar to that of other reviewers who bought the lipstick. I had a similar experience with the shade "sharon"...so beautiful in the tube, I couldn't wait to apply it, but was extremely disappointmented with the dry texture and flat color. I have ordered other shades of the lipstick to try, and at $19 I am willing to take a chance. However, the liquid minerals foundation is a little pricey to waste copious amounts looking for the right texture, or to try numerous bottles in search of a 'good batch" ! Has anyone else had this experience?
