Hello, I'm Materialscientist. I wanted to let you know that I reverted one of your recent contributions—specifically this edit to Briquette—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) 06:53, 25 November 2021 (UTC)

Hello, I'm Squeakachu. I wanted to let you know that one or more external links you added to White coal have been removed because they seemed to be inappropriate for an encyclopedia. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page, or take a look at our guidelines about links.   Squeakachu (talk) 06:58, 25 November 2021 (UTC)
