Yes. The glass hydrometer and 8.5 fl oz cylinder will touch glaze, which can contain metals that are not food safe. Rinse them after use and store them in the studio only.

Sieve and stir the glaze every time, then fill the 8.5 fl oz cylinder to the same level before lowering the hydrometer. Write down the reading with the recipe so you can match it next time.
