This purple-colored lined paper notebook is perfect for chemistry class, the science lab, your thesis or just your general thoughts, notes or journaling. The cover was designed using a vintage illustration of a bunsen burner from a chemistry textbook published in 1888 (and the original text which accompanied this illustration). The text states: "In the process of boiling, the water rapidly passes into steam. Although what is popularly called steam appears as a white cloud, true steam is never seen as such." Contains 102 lined pages inside.
