Hello, I noticed that you may have recently made edits while logged out. Wikipedia's policy on multiple accounts usually does not allow the use of both an account and an IP address by the same person in the same setting and doing so may result in your account being blocked from editing. Additionally, making edits while logged out reveals your IP address, which may allow others to determine your location and identity. If this was not your intention, please remember to log in when editing. Thank you. Drmies (talk) 20:58, 24 April 2020 (UTC)
 * If this is a shared IP address, and you did not make the edits referred to above, consider creating an account for yourself or logging in with an existing account so that you can avoid further irrelevant notices.

Hello, I'm Materialscientist. I wanted to let you know that I reverted one of your recent contributions —specifically this edit to Chemical coloring of metals—because it did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Help desk. Thanks. Materialscientist (talk) 13:40, 11 November 2020 (UTC)
