Do not cut or etch/engrave any material that might have chlorine. You can check by heating a copper wire in a flame, touching the material, and then reheating the copper wire. If the flame emits a green colour then there is chlorine in the material. See [https://en.wikipedia.org/wiki/Beilstein_test Beilstein Test] and a [https://vimeo.com/1615418 video demonstration].
