Glass transition

Why you have chosen this article to evaluate?
I chose to evaluate this article as I have some familiarity with the concept of "glass transition temperature" from class. I would like to observe and evaluate how this topic is presented on Wikipedia to learn what to look for and how to edit other articles for the class project.

Evaluate the article
Content

The article does a satisfactory job of introducing the concept of the glass transition process and the associated glass transition temperature as it relates to various glasses and polymers. However, there is missing information regarding the dependency of the glass transition temperature on pressure, for which there is backing research. Furthermore, while the article lists the glass transition temperatures for most relevant silicates, polymers, chalcogenides, and other covalent-network glasses, only silicates and polymers are elaborated on in their respective sub-sections and there is no available explanation for the significantly lower glass transition temperatures of chalcogenides and other covalent-network glasses.

Tone

The article does a satisfactory job of presenting the varying perspectives and findings of the contributors whose works shape the scientific understanding of glass transition without relying too much on one contributor's theory or model.

Sources

There is sufficient reliable sourcing backing the information presented in the article, with the exception of the claim regarding the relationship between the glass transition temperature of polymers and Gibbs free energy, for which there exists supporting research. The majority of cited sources are published research from a diverse list of accredited contributors.

Talk Page

The talk page of this article consists of a lengthy edit-war with seemingly no concrete conclusion. There are a variety of concerns raised such as the article being overall too technical for the average reader, merging glass transition and vitrification, and the insertion/removal of various sub-sections. The article is rated C-class and is part of the 'Glass', 'Polymers', and 'Physics' WikiProjects.
