A Bunsen burner can be very useful if is as used properly. There are many different types of Bunsen burners but they all use a mixture of gas and oxygen to make a flame that could be used in a laboratory. To use a Bunsen burner‚ there are several critical steps. But before one starts any experiment‚ one should always read through the experiment procedures and make sure that one clearly understands all steps of the experiment. First‚ one must make sure the main gas is on. It is very important
