According to Craig Schenning, author of "A Century of Indiana Glass" this grill plate was made in pink, green, and crystal. He also speculates that it might have been made in topaz since Indiana was producing other lines in that color during this era.
The known items that exist are a 6-1/2" plate, a 7" plate, a 9" rectangular meat platter, an 11" rectangular meat platter, a 9" oblong vegetable bowl and the 10" grill plate (shown above). These are the only catalog listings.
