âWell Mr. Customer, let me go check with my manager to make sure the car is still available and work out the best figures that will help you make the best decision.â Show your customer your proof book or evidence manual when you run for the numbers.
Laboratory tests are usually negative in patients with HADD. CHA crystals are 75-250 nm, and are not visible with light microscopy, except when the crystals form aggregates. The CHA crystals are non-birefringent in polarized light.
Natural Chalcanthite crystals are very rare in nature. Well-formed crystals are easily grown synthetically from copper sulfate solutions. This can be done by dissolving a readily available chemical salt called copper sulfate, and then letting the water evaporate. This leaves behind a crystallized mass of Chalcanthite which can crystallize beautifully if grown properly. If a Chalcanthite crystal looks to good to be natural, it probably is, as good natural crystals are very hard to come accross.
