Test for chlorine in materials being used to preserve artifacts in the storage, like plastic bags, plastic boxes … etc.
- Metal wire (copper)
- Materials to be tested
Heating the copper wire.
We heat the copper wire until it gets red, and then we stick it to the material that we want to test to take a sample. Then we put the copper wire again over the fire. If the color of the flame was green, it is asign that there is chlorine, but if the color of the fire doesn’t change, it is sign that there is no chlorine in the material.
Looking for a green flame that indicates a positive reaction.
