A: Copper is classified as a metal on the periodic table and is therefore not classified according to family in the manner that plants and animals are. Copper is red-colored. It is malleable, ductile, and a good conductor of heat and electricity.
For a hard-boiled egg, start the egg in cold water and bring up to the boil. Once the water is gently boiling, set the timer for between 7-10 minutes depending on how well cooked you like your eggs. The longer you boil the egg, the firmer it will be. Once cooked, plunge the hard-boiled egg into plenty of cold water for one minute. Drain and cover with more cold water.
Ease the egg into the simmering water and let cook. As a general rule of the thumb, cooking time should vary between two and a half to four minutes. However, how long it takes to poach an egg this way will also rest on how well you like your eggs done. In any case, poaching an egg in boiled water will not go beyond four minutes to get a firm white but a still runny yolk.
