Here's your answer...
The temperature of the earthen pitcher will be less than that of the metal utensil.
Articles made of earth (mud) have small pores in them, which absorb water and expose them to the outer atmosphere. These pores are not present in metal utensils.
This way, more water surface is exposed to the atmosphere in an earthen pitcher than in a metal utensil.
Exposure of water is factor in the speed of evaporation. Water evaporates faster from the earthen pitcher than from the metal utensil, due to the increased exposure.
When a liquid evaporates, it absorbs heat from the bodies in contact with it, to convert to water vapour. This reduces the heat and temperature of those bodies.
Since water is evaporating relatively faster from the earthen pitcher than the metal utensil, the pitcher will be cooler.
