This item is a vintage ruby-flashed and clear pressed glass pedestal cake stand (also frequently referred to in vintage catalogs as a cake salver or torte display plate), dating from the mid-20th century (circa 1950s–1970s).
The design features a clear glass plate base pressed with an underlying grid/block pattern, split into quadrants by four raised directional lines, and structured with a small square center recess. The vibrant red color around the wide rim is ruby flashing (a thin layer of red glass or stain fused over the clear glass). It is completed by a flared, clear glass hollow pedestal stem.
This specific 12-inch style was produced by mid-century American elegant glass manufacturers such as the Indiana Glass Company or Tiffin Glass.
Large 12-inch cake stands from this era are highly collectible due to their practical size and seasonal aesthetic. On vintage secondary platforms like eBay and Etsy, pieces in excellent condition fetch the top end of this range.
Because the ruby flashing is completely smooth and free of any scratches, wear, or embossed patterns, your cake stand is in excellent vintage condition.
This narrows its manufacturing identity down to a mid-century Indiana Glass Company pattern (such as their sleek mid-century utility lines or clean-rim variations). The absolute smoothness of the red border significantly helps its presentation value, as ruby flashing from this era is notoriously prone to kitchen knife scores and flaking.
