Expert Answer:
Mixture of ethyne and air cannot be used due to hazard associated with ethyne's intrinsic instability; samples of concentrated or pure acetyle will explosively decompose in air. Acetylene can explode with extreme violence if the pressure of the gas exceeds about 200 kPa (≈39 psi) as a gas or when in liquid or solid form.
