Glass chemistry is important for environmetal protection, e.g., for glass recycling, for developing lead-free crystal glasses, fiberglasses with reduced boron content, glasses free or arsenic, antimony, barium, and strontium for flat panel display substrates, and radioactive waste vitrification strategies.
The Sol-gel technique may be used for making bulk glasses of unusual composition that can not be obtained otherwise by the traditional melting. In addition, coatings may be prepared by the sol-gel technique.
Glass-ceramics are made as glasses by melting. However, afterwards a tempering step leads to devitrification, to crystallization. Glass-ceramics may have improved fracture toughness and thermal shock resistance compared to normal glass.
Porous glass, made by phase separation of sodium borosilicate glass or similar compositions, continues to be one of the most investigated amorphous solids, applied in industry, medicine, pharmacy research, biotechnology and sensor technology.
Hollow glass microspheres are used, among else, as lightweight filler in composite materials, and serve as storage and slow release medium for pharmaceuticals, radioactive tracers, and hydrogen.
The chemical analysis of glass compositions (in particular for archeological purposes) is discussed in the article Robert H. Brill.

Things to do, Glass Chemistry:

Creation of new articles, e.g., Glass former, Glass modifier, Glass coating, Mixed-alkali effect, ULE glass (see patent US2326059).
Expansion of the article about Otto Schott, the first glass chemist.

Introduction: The introduction does not yet include all sections accordingly, for example, the art and history section are not well introduced.
Proper referencing: Most sections are not properly referenced, e.g., they contain some statements at the end of paragraphs that have no reference. These sections are: Glass ingredients Done -KAP03(^{Talk • Contributions • Email}) 15:23, 21 May 2017 (UTC), Contemporary glass production, Network glasses, Glass versus a supercooled liquid, Behavior of antique glass, Color, History, Islamic world, Medieval Europe, and Murano glassmaking.
Content encompassing the topic? A small section about glass coatings should be included, referring to insulated glazing, low-emissivity, windshield, smart film, smart glass, water-repellant glass, glass fiber sizings, laminated glass, and bulletproof glass. The paragraph under Contemporary glass production seems too short in view of the importance of the subject. Similarly, a section about Fiberglass Done -KAP03(^{Talk • Contributions • Email}) 15:20, 21 May 2017 (UTC) and Glass corrosion appears appropriate.
History section: Roman glass should be shortly discussed; just the reference to the main article is not consistent with the other sections in the glass article. The same is valid for Anglo-Saxon glass and Forest glass (Late medieval Northern Europe). As a whole, the topic "glass history" is still not shown as unitary, but composed of many pieces that not always fit well.

Short discussion of further glass color topics with reference to the main articles:
- Photochromic glass
- Smoked glass
- Glass coloring using vanadium oxides
- Glass containing Cu or Ag ions, colored on the surface by exposing to hydrogen at elevated temperature, thereby reducing Cu or Ag compounds to the metal
- Coloring by ion exchange
- Surface coloring of glass by organic coatings or via the sol-gel method
Discussion of the coloring mechanism in ionically colored glasses and striking glasses, e.g., using the crystal field theory
