How would the melting range of a pure organic material be changed if there was a tiny shard of broken glass inside the melting point capillary?

Melting point range will not be affected.

Explanation:

Tiny particles of broken glass inside the melting point capillary, then the melting range of a pure organic material will not be affected, as the glass will not affect melting point determination as glass will not serve as impurity that can alter the melting point, so the melting range of a pure organic material will not be affected.
