Christine, I had no troubles with CIM Crocus so far. I did not try to encase it because I like the color as it is but added some decorations.
Sorry for these beginner's fuglies (all survived the fiber blanket and the kiln later), all on base of crocus - with a band of goldstone, two with purchased murrini slices and dots of Effetre pea green, with twistie (as far as I remember I mixed there Reich mystic red, some Effetre orange and yellow, CIM poison apple, Effetre periwinkle, CIM ming and some effetre violet transparent). So I would consider Crocus as a friendly color at least for the surface decorations
Rudy, there is a chance that the rods were mislabeled or mixed up at Delphi's warehouse - they carry pretty huge stock of so many items that it is technically possible.
