These stem and spot-face areas are the only two locations on an EMD bell casting that actually undergo precise machining operations. The oldest EMD bells are generally unmarked and found with smooth (or "ground") finishes. Although they may appear to be polished, closer examination of these bells will exhibit indications of fine grinding.

Eicher et al. have generated complex 3-germ-layer human gastric organoids from pluripotent stem cells. These 3-germ-layer organoids contain glandular epithelium surrounded by multiple organized layers of functionally innervated smooth muscle. Manipulating this system revealed key developmental roles of neural crest cells on gastric epithelium and mesenchyme.

The goals of fine grinding are to prepare the curved mirror face so that it is ready for polishing and figuring and make any adjustments of the focal length. Previously in rough grinding we deepened the center of the mirror's face either by grinding with coarse grit and a tool, slumping in a kiln over a mold, or purchasing the glass pre-generated.

Grind them even more and you get fine powdery ground coffee. Fine ground coffee has heavy extraction, allowing for the strong flavor to come out in your brew. Coarse ground coffee has less extraction and has less intense flavor by comparison (the exception is when the immersion method is used). Some brews prefer certain levels of grounds.
