Five invaluable books are at your disposal to assist in identifying Haeger pottery and shedding light on crucial details such as the time period of a piece and the name of the glaze. Many Haeger pieces are marked with numbers, serving as a significant clue and a starting point in the identification process. Occasionally, specific pieces were crafted during certain periods as part of a new product line, only to later fall out of favor, be shelved, and subsequently reintroduced, sometimes decades later.

The diversity and abundance of glazes further complicate matters, with the glaze itself often providing clues about the production year. Certain glazes were produced only during specific timeframes, hinting at the age of any piece sporting that glaze. While many pieces have a clear initial production date, they could have been manufactured at any time thereafter, especially if the item became a staple in Haeger's catalog.

It's worth noting that while there's no single definitive source for information on every Haeger piece ever made, our resources serve as an excellent starting point for your research. We've dedicated ourselves earnestly to provide accurate information about your pottery.
