Mysterious time capsules of Germany

These construction workers, while demolishing an old building in Germany, discovered strange holes under the foundation. It was a passageway to a laboratory containing ancient components dating back to the 17th century. The government invited scientists who signed a non-disclosure document before entering. Later, they noticed mysterious walls in the tunnel basements that were different from the others. One of the researchers carefully broke the bricks, revealing not a hidden passage, but an actual time capsule. The amazing thing is that they found another 50 such capsules, each one unique. Opening them, they found glass containers wrapped in paper, with the inscription that these dangerous substances were created in the 17th century. This raises intriguing questions. For which generations were these substances intended? How dangerous could they be to humanity?
