Many times, we find several stones in the backyard that are not just “stones.” They are in the category of precious rocks or stones. These are the ones having great market value.
But these stones must be made ready before any further processes. Cleaning them is necessary. But this process needs to be understood, as merely any such process of cleaning these stones is not recommended.
The following article concentrates on how we can cleanse valuable rocks in your backyard.
Something with the word “acid” feels dangerous. However, oxalic acid is simple to find, utilize, and convenient for housing. It is present in several vegetables. It is utilized to remove the iron oxide (brown) mark on all stones. Specimens gathered at Phoenixville, Ellenville, Case Quarry, NH smoky quartz, and others rinse up properly using oxalic acid. Zeolites do not react as well. It would be best if you experimented earlier on smaller pieces.
- Get a plastic container of one gallon, 3/4th with distilled water.
- Put in the OA crystals. Mix for five minutes. Be cautious not to breathe any powder while mixing the crystals.
- After the OA is mixed, top off the vessel to an entire gallon. Point out the container. Keep it out of reach for others.
- After you are ready, place the stones in a plastic vessel. Add sufficient OA solution. Keep it aside for days.
Safety is necessary. OA solution is very toxic. It can get soaked in the skin. It gets gathered up in organs gradually. The same is for the fumes. One must never boil the mixture. There must always be efficient ventilation while using the boiling solution.
After the iron color has dissolved, then one can displace the particles (with gloves on). Rinse in flowing water for three hours. In case there’s hard water in the area, it is recommended to utilize distilled water for the first few washes to resist the making of insoluble oxalates. It will mark the specimen yellow after drying.
Then wet in clean water for a day. Change the water as frequently as possible. The best way for rinsing minerals is:
- Alter the water after each minute for one hour.
- Alter the water after each hour for a day.
- Alter the water each day for one month.
Wash the rocks cautiously in water. Put away any foreign sand and particles. To let the acid study, if possible (sand and dust carry iron oxide. It will dissolve in the acid swiftly), Place the stones in a huge plastic vessel with a cover that could be tightly restricted.
Let the rocks dry. Displace the vessel outside to a place with better ventilation. Put in sufficient acid to shield the rocks. Always have thick rubber gloves on. Also, be extra cautious so that acid does not splash out.
Based on what you are rinsing with the acid, leave it for 5 minutes to 5 days.
Mechanical methods are utilizing the force of some means to rinse foreign particles or dirt. Naturally, this way has the danger of destroying the rocks by scratching or breaking the particles. As usual, care must be undertaken to look for the process on lesser particles to check if there is any problem due to the process.
The mechanical rinsing of particles starts from a toothbrush to ultrasonic rinses, with water guns to sandblasting.
Brass Brush and Dental Picks
With this primary rinse, there will be sand and dirt deep in the dents in the crystals. These can be washed with a group of dental instruments. They are available in a diversity of types and sizes. Frequently a friendly dentist will provide his old instruments. These picks are of steel and thus harder. So be cautious not to utilize a scratching hit. Just loose out the dry, caked dust in the dents.
Naturally, with loose particles, lifting is not the issue. They will just come off by force. With minute particles, we must get an ultrasonic rinse. These are normal stainless-steel utensils with piezoelectric drivers joined to the bottom. They frequently have attached timers and heaters. When switched on, they reverberate the mixture at ultrahigh frequency, helping cavitation, the making, and breaking bubbles.
Sand blasting seems old. But is more popular than ever thought. The pink tourmaline in purple lepidolite solid has been sandblasted to bring out the tourmaline. The sandblasting washes the softer lepidolite very swiftly. It renders a more natural look than chisels.
These tools return at 36,000 cups. They are very able to rinse matrices. Many companies opt for these as the best tools for rinsing calcite from willemite Particles as the acid will engrave willemite.
The action is a joint of sandblasting and ultrasonic. The gun causes a fine, greatly fueled jet of water that will rinse most clays and dirt. It is very energetic, though. Hence it is not efficient for minute minerals. The advantage is that one can place mixtures barring water within the gun.
