Hello Soccer !
Well .... it all depends on what you mean with "burning".
What happens is this : salt requires energy to dissolve into water. Ice requires energy to melt into water. Combine the two and the mix redraws a lot of energy from whatever is touching the mix (and less energy means a lot colder).
100 years ago this was the only way for people to prepare ice cream (as there were no freezers). The only time of the year that ice was available was of course winter time (unless you lived near high mountains).
The mixture can reach about - 25' Celsius = - 13 Fahrenheit , and that can "burn" your skin.
Note : "burning skin" is caused by a too big temperature
difference between the skin and what touches the skin. So you can "burn" your skin with something that is too hot, and with something that is too cold.
I hope this answers your question !
