Microwavable system and method of facilitating microwave heating of liquids

A system for facilitating microwave heating of a liquid, comprising:

• a cylindrical holder for receiving at its interior the liquid to be heated by microwave energy, said holder being at least partially composed of microwave energy transparent material;
• shielding means being at least partially composed of high microwave reflectivity material and being disposed on a surface of said holder for blocking microwave energy from entering a selected interior portion only thereof to prevent direct microwave heating of the liquid in said selected portion so that there are shielded and unshielded portions of the liquid being heated to cause substantial uniformity of temperature throughout the liquid being heated;
• and
• means for facilitating axial adjustment of said shielding means relative to said holder to enable said shielding means to be positioned such that the upper blocking portion thereof is positioned at or above the level of the liquid disposed within the interior of said holder whereby the top layer of the liquid is shielded from direct microwave heating to prevent unwanted heating of a top layer of liquid.
