With difficulty.

Explanation:

As a non-molecular species, sodium chloride has exceptionally high melting and boiling points. The melting point of sodium chloride is #801# #""^@C# (this I knew from memory); the boiling point of sodium chloride is reported to be #1413# #""^@C#.

If you have a blow torch, you can certainly melt sodium chloride in a crucible. The fact that you have to separate discrete positive and negative ions in the melt rationalizes the elevated boiling point of sodium chloride.
