An indoor exhibit within the Museum Geologi Bandung, Bandung City, Indonesia, displays a collection of approximately 35-40 liquid samples. These samples are arranged in multiple rows on a white, elevated display surface. The collection comprises two main types of containers: eight clear glass bottles with ground-glass stoppers, which contain dark, viscous, opaque liquids; and approximately 27-32 plastic vials with screw-on caps. The plastic vials feature both white and blue caps and hold liquids of varying colors, including clear, light yellow, orange, reddish-brown, and predominantly dark brown to black opaque substances. Some plastic vials have faint, illegible labels. The background features an informational panel with Indonesian text that partially reads: "...bangan secara tradisional pada sumur minyak tua peninggalan Belanda di daerah Kawengan Bojonegoro, Jawa Tengah." This translates to "...traditionally developed in old oil wells, a Dutch heritage in the Kawengan area, Bojonegoro, Central Java." Below this text, a dark, indistinct image of an industrial structure, possibly an oil rig or derrick, is visible against a blue background. No individuals are present in the scene.
