What is the pink set you are looking at ?? Can you post a pic of it ?? Another note to the above post is who made the item you are interested in !! Mfrs are important if you know it !! Some unmarked items are easy to find by description and others are not !! And separate the classification between pottery/china and glassware !! It will be easier to research for you !! In other words,,the McKee set is opaque glassware but even though china/porcelain/ceramic is opaque,,it is not glassware !! How to tell older milk glass from the new,, hold one of the cups by the handle and look through the cup top to bottom toward a bright light,,sunlight is best but any bright light source will work !! You can see flashing yellow/ orange and red as you move the cup !! Most new milk glass will not have the fire,,as it is called !!
