Jewelry
The jewelry box is a place that pure elements might be found in the home . gold , silver ,and platinium are frequently used in bracelets and rings.gold and silver used in jewelry are nearly always actually a mixture .pure gold( called fine gold or 24 1karat gold ) is too soft to be very useful in jewelry so it is frequently mixed with silver ,and silver is usually mixed with some copper ,to make the metals hard enough to stand up to the wear and tear of usage ( see figure 18.24)
