As far as tattoo ideas go, this illustration is on fire! Shown here is a plate depicting the “Atomic Theory of the Hydrocarbon Flame” from A Text-Book of Medical Chemistry and Toxicology (1908). The accompanying caption reads, “The red discs are oxygen atoms, the black are carbon, the blue are hydrogen; the black circles in the yellow zone are incandescent carbon atoms emitting light. The products of the combustion are water and carbon dioxide.” As explained in the textbook, the illustration shows “what the chemist imagines to occur when he explains the burning of common illuminating gas in a luminous flame” (page 113). . . #OthmerLibrary #TattooableTuesday #TattooInspo #TattooInspiration #TattooIdeas #Tattoos #Flame #Chemistry #FlameTattoo #Candles

Upon first glance, you may think you are looking at some colorful marbles and/or sea urchins. In both cases you would be incorrect. What you are in fact looking at are illustrations of fat, butter, beef, and lard crystals under a microscope. The illustrations accompany the 1886 reprint of Dr. Thomas Taylor's reply to "Science", relating to the crystals of butter, animal fats, and oleomargarine. . Figure 10 depicts a butter crystal as seen under polarized light and selenite plate; Fig. 11: a boiled “oleo” crystal by polarized light; Fig. 12: a boiled “olelo” crystal by polarized light and selenite plate; Fig. 13: a lard crystal; Fig. 14: lard crystal under plain light; Fig. 15: lard crystal under polarized light and selenite plate; Fig. 16: oleomargarine; Fig. 17: pure butter, both unboiled, polarized light and selenite; Fig. 18: boiled beef fat crystal under polarized light and selenite. . . #OthmerLibrary #TattooableTuesday #tattooideas #tattooinspiration #tattoos #butter #margarine #19thcentury #scientificillustrations
