Lacquer is a clear or colored coating (called a varnish) that is often used to give wooden surfaces a glossy look. Lacquers are dangerous to swallow. Breathing in the fumes for a long period of time is also harmful.
Poisoning from lacquers is due to hydrocarbons, which are substances that contain only hydrogen and carbon.
Lacquers are products that are used as a clear finish for wooden surfaces, particularly floors. They are sold under various brand names.
