Kathleen,
 The original  compound came in three temperature ranges.  O.C.T. Roman
numeral( l)  for 0 to -15 degrees, , O.C.T.( II ) for -15 to -30, and
O.C.T.( III ) for -30 to -60. Today you have only one choice. I think
"O.C.T."  Compound was a copyright name at one time and  competitors now
refer to "freezing compound"  for their products.
