Instructions
Designate a workspace for tumbling and cutting your rough agate. Ensure that the area has ample light for working and is clear of any dirt, dust or debris.
Open the rock tumbling mechanism and insert the rough agate chunk along with the coarse grinding powder (available at most gem suppliers). Add water to the rock tumbler chamber until the particles are submerged, close the tumbling mechanism and begin the tumbling process. Let the tumbler run for one week.
Clean out the tumbler and replace the stone and water along with a fine grinding powder and restart the tumbling process for one more week.
Remove the tumbled agate and dry off the stone, removing any attached grinding powder or debris that may be attached to the surface. Decide on the types of cuts you wish to make on the rough agate, such as: halving the stone, carving it into slices or cutting shapes into the stone.
Put on your safety goggles and gloves and bring your tumbled agate to the band saw. Turn the saw on and carefully insert the stone by gently feeding the stone with two hands. If the stone section is too small to safely hold in place while the saw is in motion, secure the stone between locking pliers, such as Vise-Grip, and carefully direct the stone through the saw while holding the plier handles. Repeat for all desired cuts.
Polish each cut piece by placing each individual slice into the tumbler for several days, using water and polishing powder.
