Why an Unmarked Jar Suits Hydrometer Readings
Hydrometer jars are deliberately left without printed graduation markings because their job is to hold a stable, sufficiently deep column of liquid so a separate hydrometer can float freely and settle to its equilibrium depth — the reading is taken from the hydrometer stem, not from the jar. A round base and the absence of a pouring spout keep the internal diameter consistent from top to bottom, avoiding the taper distortion a spout can introduce near the rim, which matters when a hydrometer needs adequate clearance from the jar walls to float without touching them. Borosilicate glass construction resists the mild chemical exposure common in specific-gravity testing of oils, syrups, acids and other industrial liquids.
