The easiest way to tell reproduction pottery from authentic pottery is the makers mark. Take the piece of pottery and pick it up. Most pottery pieces are marked on the bottom. Look at the mark and compare it with marks the original pottery company had. There are books that show most of these. Also why you are looking at the bottom look for natural wear. Generally if a 100 year old piece of pottery looks brand new it might be.
Look at the glazing and colors used in painting the piece. Most authentic pottery pieces are a dull or matt finish. The colors are generally earthtones to. Watch out for pieces that shine or bright colored pieces. There is a few but it is not the norm.
Examine the size of the piece alot of reproduction pieces change the size just a little so it is legal. Measure the piece and compare to your reference book. I know roseville and hull have excellent books out there.
