Dear Materialscientist - first of all, thank you for your comment. I wanted to add an information in the article since measuring the viscosty by use of an oscillating quartz crystal is a unique measuring method which might be of interest for the reader. It was not meant to be promotional but I do understand the critic and will alter the information accordingly. Johanna321 (talk) 12:41, 2 July 2015 (UTC)[reply]
