Recent edit to Zeolite
Hello, and welcome to Wikipedia. I wanted to let you know that I removed one or more external links you added to the Zeolite article, because they seemed to be inappropriate for an encyclopedia. You may find our linking guidelines helpful in this regard. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you!
