After such an experience many people, myself (particularly) included, tended to look dubiously at peroxide and to pass it by on the other side.” ― John D.

| Jul 15, 2020 at 16:42 | comment | added | Ed V | I did not downvote, but I am a bit concerned about the “playing with” 60% hydrogen peroxide. It is dangerous, causes nasty painful burns (worse than the 30% grade) and practically everything catalyzes its highly exothermic decomposition. Silver, including sterling silver teaspoons, is one of the many substances that act as efficient catalysts. You may well be lucky nothing really bad happened. Please read up on hydrogen peroxide and be safe: use the appropriate PPE! | |
