A beneficial technique, using glycol ethers, to help reduce the amount of amorphous organic matter (AOM) in palynological preparations is described. A brief history of glycol ethers, and their historical applications, is also discussed. The technique, which is relatively simple, inexpensive and rapid, can easily be applied as a terminal step to most maceration schedules. The technique does not appear to have any deleterious effect on palynomorphs, but testing treated and non-treated residues is recommended. Two examples, one Late Devonian and one Middle Pennsylvanian in age, are provided to illustrate the effectiveness of glycol ethers in removing AOM.
