Date an object

Answer what you are sure of and leave the rest. Every question is optional, and the list narrows as you go.

Style is copied; construction is not. A convincing Victorian look can be forty years old, but a circular saw mark cannot predate circular saws. Answer on how the thing was made rather than what it looks like.

1.What is it made of?

optional

The broadest split, and the one that decides which evidence is worth looking for.

2.What construction evidence can you see?

optional

Look at the parts nobody finished — the back of a case, the underside of a top, the base of a bottle. Pick everything that applies.

3.Are there any marks?

optional

Marks are the fastest dating evidence when they exist. A registry diamond, a hallmark or a patent number can date an object to the year.
