What is a state casket primarily characterized by?

A state casket is primarily characterized by a design that features a 90-degree angle to the bottom. This design aspect is specific to state caskets as they are typically rectangular in shape, providing a formal and dignified appearance suitable for high-profile funerals or state occasions. The square corners contribute to a more traditional and stately look, which is often preferred for ceremonial uses.

The other characteristics, while noteworthy in their own right for various casket styles, do not apply to state caskets. For instance, a round shape with curved corners is not typical for a state casket, which aims for a more angular and formal profile. Intricate carvings, while beautiful, are not the defining feature of state caskets, which prioritize elegance and simplicity in their design rather than ornate detailing. Lastly, while metal can be used for state caskets, the defining characteristic is not their material but rather the distinct angular design.
