In Figure 1, the top row of petri dishes shows the crystallization of a coating made with partially hydrogenated oil: the petri dish on the left was cooled, and the one on the right was left out at room temperature. Both have a good gloss and show no signs of bloom. The bottom row of petri dishes shows the crystallization of a coating made with fractionated oil: the petri dish on the left was cooled, and the one on the right was left at room temperature and developed bloom and "skin" surface formation.
