Clean the metal if necessary. Both brass and copper develop a patina with age, usually green but sometimes other colors.
Hold the metal under white light. If the metal is highly polished, you may see false colors due to reflected light.
Identify copper’s reddish color.
Inspect yellow brass.
Learn about red or orange brass.
Identify other brass.
Solid brass is not magnetic. If the magnet sticks, the item is usually steel or cast iron, with a brass plating. If the magnet does not stick, you can test further by scratching a hidden area with a sharp tool. If you see a shiny yellow scratch, the item is likely solid brass.

How can I tell if something is made of brass
Don’t let the room stay so damp. Soaking will chip a person’s paint. Only
work with the hatch increases water heating. Due to the heat of hot potable water, metal expands faster than paint and all paint cracks and/or flakes off.

Will a magnet stick to brass
Metals that magnets do not attract
Some other naturally occurring metals, such as aluminum, copper, lead, gold, and silver, do not attract magnets because they are weak metals. However, properties such as iron and stainless steel can be added to these mining crops to make them durable.
