Material name
1798 on a placard, orange panel or shipping paper
It can stand for either of two ERG 2024 entries: “Aqua regia” and “Nitrohydrochloric acid”. Both use Guide 157, so the number alone is enough to find the guide. On a numbered orange panel, 1798 is the lower number (how to read an orange panel).
