This article shows a scientometric analysis for glass researchers and compares it with those for researchers in two fashionable research topics, representing the science-push area "graphene" and the market-pull area "lithium ion battery." Also presented are similar statistics for two widely different macro fields, "materials science" and "mathematics." While productivity (no of published articles) of a researcher and his/her H-index are found to be correlated, these correlations are very different for different research fields, depending on their size, fragmentation, interdisciplinarity, and on the community's publication and citation culture. The paper also explores the correlation between citation statistics and scientific quality and find it to be elusive. While certain bibliometric indexes indicate how active, prolific, and visible a researcher is, it's argued that quality - evaluated by the originality, strength, reproducibility and relevance of the findings of a researcher's publications (as judged by peer review) - is much more important than the number of published articles and citations, and this is where efforts must be concentrated by researchers and evaluating bodies.
