Common use nitrates are very easy to process. When components have a more gummy texture, that you want to mill. The coffee grinder mills are usually extremely frustrating to use, or just not effective. My standard color batch size is 18lbs, so I'm usually prep-ing 9lbs or more of either nitrate at a time.

Strontium was once widely used in the separation of sugar from sugar beet molasses. The sugar was precipitated as strontium disaccharide and then released with CO 2 to produce sugar and strontium carbonate. Strontium was also added to the glass of old-style television sets to absorb the secondary X-rays emitted by cathode ray tubes.
