### substance | conductor | copper:

Copper sulfate
* appears to be toxic to catfish held at low temperatures under laboratory conditions.
* can be corrosive to the skin and eyes
  - kill plants by disrupting photosynthesis
* comes in several forms depending on how finely it is ground.
* common supplement source for horses.
* creates a blue flame and who knows what evil that produces.
* is approved for use by certified organic growers
  - blue and odorless
  - classified for shipping purposes as a hazardous substance or hazardous waste
  - corrosive to galvanized containers
  - crystal
  - effective only for algae control
  - highly corrosive to plain steel, iron and galvanized pipes
  - inorganic compounds
  - ionic compounds
  - practically nontoxic to birds
  - probably one of most widely used fungicides by farmers and gardeners alike
  - somewhat toxic to humans
* is toxic substances
  - to aquatic invertebrates, such as crab, shrimp and oysters
  - triclinic
* is used at whatever concentration is safe in the existing water chemistry
  - in copper plating, in fabric printing, and in electric cells
  - water soluble, and dissolves fairly easily when mixed with water
* makes triclinic crystals.
* synthetic form of copper.
+ Copper(II) sulfate, Safety: Sulfur compounds :: Copper compounds
  * Copper sulfate is somewhat toxic to humans. U. S. Environmental Protection Agency. 1986 Guidance for reregistration of pesticide products containing copper sulfate. Fact sheet no 100. Office of Pesticide Programs. It is very toxic to fish, though.
+ Crystal structure
  * The 'crystal structure' of a chemical is the shape of the crystal. There are several shapes of crystals. Sodium chloride is a cube. Copper sulfate is triclinic. Most things, even metals, have crystal structures. Some crystals fit more atoms in them than others. These crystals weigh more.
+ Triclinic: Chemistry :: Minerals
  * A 'triclinic' crystal is shaped almost like a rectangle. It is slightly bent, though. Copper sulfate makes triclinic crystals.

Dietary copper
* affects lipid and cholesterol metabolism in finishing steers.
* influences reproductive efficiency of queens.
* is important to doctors and nutritionists.

Excess copper
* can cause stomach problems.
* decreases molybdenum levels.
* is stored in the liver.

High copper
* can be toxic.
* interferes with zinc, which is needed to manufacture digestive enzymes.

Pure copper
* Most pure copper has conductivity
  - thermal conductivity
* is alloyed with many other elements to produce minor changes in properties
  - obtained by electrolysis
  - red-orange in color
* is soft and can be drawn into wire or hammered into desired shapes
  - enough to accept a charge of diamond dust if properly applied
* much better electrical conductor at normal operating conditions.
* single phase alloy.

Solid copper
* is copper
  - solid objects
  - the primary material used, with some accents provided by bronze and brass
* makes for the lightest batter for omelets, souffles, zabaglione, etc.

Electrical conductor
* Every electrical conductor carrying a current has a magnetic field surrounding the conductor.
* Most electrical conductors conduct heat.
* allow electric current to flow easily because of the make up of their atoms.
* are placed on the cell to absorb the electrons
  - usually metal because metals generally have high conductivity
* attach to the protector and run down to the conductor.
* have electric charges that move freely.
