Expert Answer:

Brass is a good conductor of heat. Therefore when one touches the brass tumbler, heat is conducted from the body to the tumbler easily. So the temperature of the body reduces the and the brass tumbler feels much cooler than a wooden tray.
 
In case of wooden tray, wood is a poor conductor of heat and therefore very little heat is conducted from the body to the wooden tray.
Hence there is a very small drop in the temperature of the body and it does not feel cool.
