Resumo: | This work presents an evolution profile of labels and containers of commercial chemicals employed in laboratories since 1870. Most chemicals were made in Germany before the Second World War, after which many other manufacturers arrived on the Brazilian market. North-american products were dominant in the 1940s, but Brazilian chemicals have increased their participation along time. Labels presented increasingly more information, from originally simple names of the compounds at the beginning of the XXth century to the data presented today such as chemical formulae, safety regards and detailed chemical analysis. The raw material for container manufacturing also changed: glass was dominant until the 1950s, but nowadays plastic flasks are preferred whenever possible. Cork covers were replaced by screw caps. The diversity of commercial products also sharply increased with time, especially after the 1950s, following the many new and specific applications of chemicals for research and commercial purposes. |

This work presents an evolution profile of labels and containers of commercial chemicals employed in laboratories since 1870. Most chemicals were made in Germany before the Second World War, after which many other manufacturers arrived on the Brazilian market. North-american products were dominant in the 1940s, but Brazilian chemicals have increased their participation along time. Labels presented increasingly more information, from originally simple names of the compounds at the beginning of the XXth century to the data presented today such as chemical formulae, safety regards and detailed chemical analysis. The raw material for container manufacturing also changed: glass was dominant until the 1950s, but nowadays plastic flasks are preferred whenever possible. Cork covers were replaced by screw caps. The diversity of commercial products also sharply increased with time, especially after the 1950s, following the many new and specific applications of chemicals for research and commercial purposes. |
