 Although the pottery was in fact of minor economic significance and survived for only twenty years on a site used for other clay products for 69 years, its products are visible and collectable where pipes, chimney pots, tiles and bricks have for the most part remained functional and less well regarded.As an aspect of Lithgow Valley Colliery, the most long-lived of all Lithgow enterprises, the clay products division offered employment and company facilities (such as quoiting) which were a significant part of Lithgow life for a century.Lithgow Valley Colliery & Pottery Site was listed on the New South Wales State Heritage Register on 2 April 1999.
