A good place to keep saw blades for silver smithing is in a used, transparent "Bic" ballpoint pen. Birdie Nichols of Chagrin Falls, OH, removes the used pen filler by grasping the metal tip with pliers. The empty pen will hold a package of 12 saw blades which can be kept clean by replacing the plastic cap. A label marker will help identify which size blade is stored. Small drills can also be stored this way.
For field tripping in areas with no water, carry a can of shaving cream, push-button type, for cleaning hands. A squirt, a washing motion of the hands, then wipe off. Presto! Clean hands!
We recommend sawing about 10 degrees away from directly parallel to the grain. This way, when you dome the stone, you will get a bullseye effect. Malachite is a fairly soft stone, so try to leave the slabs a little thicker than other materials. When grinding, we recommend always wear a breathing mask. Malachite can be toxic and can make you very ill. After grinding sand first on a new 600 sanding belt, then finish sanding on a very worn out 600. Finally, for polishing, we recommend ZAM on hard felt. Give the stone a little extra time and the polish will keep coming up better.
When sawing geodes, look for the largest dome on the specimen. This dome was in an upright position while it was formed. Saw through the largest dome and it is likely you will get the best picture. If the specimen is elongated or egg-shaped, saw lengthwise to obtain the best exposure. While there is no certain means to determine the interior of an agate nodule, or geode, these ideas are likely to be beneficial.
Fire Agate is actually a chalcedony with a layer of iridescent limonite which is trapped between the layers of chalcedony. The layer is so thin that it is sometimes less in thickness than a breath upon a window pane. The deposition of limonite is such that a dense spot is where the best colors are usually dominant. This form of "fire agate" is usually botryoidal. Work with caution!
Never sleep in a freshly cleaned sleeping bag. The carbon tetrachloride used in the cleaning process can put you to sleep permanently! When you have a sleeping bag cleaned, air it well before using.
Using a stick or eye dropper to drop some weak hydrochloric acid on a scrap piece of calcite, watch what happens. The hydrogen ion in the acid causes the carbonate to become unstable and breaks apart the carbon and oxygen molecules and combines with the hydrogen to become carbonated water. The "fizz" is a good identification factor for carbonate rocks.
