Tin metal are wild use in making glazes. To opacity glazes we usually hand made it, the most popular use of tin in glazes are hand decorated tin glaze earthenware of the 1700/1800s. Tin has a very high melting temperature, and it's very expensive, it can react with tinanium and rutile to variegate the glaze.

Properties
There are two types oxide of tin: Tin oxide and Tin dioxide. Tin (II) oxide is also called Stannous oxide.
Compare with Tin (II) oxide, Tin (IV) dioxide is more common, when you heat Tin dioxide in the air it will easily change into Tin oxide. Tin dioxide is wight dust and Tin oxide is black.
When Tin oxide heated under an inert atmosphere disproportionation will occur with the Tin metal and the Stannic oxide are being formed in equimolar proportions.
The electronic band gap is between 2.5eV and 3eV.
Occurrences
Tin oxide appears as black dust and when it was heating in a not enough air position it may be apoised as a pure thing. It also can be used as part of the creating of ruby glass, like the reducing agent. We can use Stannous Oxide for divalent into salts or tin compounds; and Stannous oxide s not use for esterfication catalyst as much as use for the other things.
Uses
Tin oxide has a lot of different physical uses and characteristics. Through the new technical result, the tin oxide can be used for many things.
The components of electronic and electrical; polished the marble like thing; melted the glass; make brake pads and friction stuff; make contribution of sputtering technology; be used as antistatic coating; filled the plastics; made the sheer materials for exhibition; detected catalysis and gas; weld optical surface area; exchanges ion for radionuclide; colored and glazed ceramic. [1]
The range of tin oxide may affect the rank of passed the domain of the surface area and the particle size. It also can affect the pigments of high quality ceramic, friction and brake materials, and tin oxide’s electrodes of glass melting, carefully controlled the range of ranks of tin oxide for suing on silver and tin oxide electrical connect stuff, to do the best of put the best size of the particle for the performance of margin and the durability in this exacting application. [2]
Alpha stannic acid is one type of hydrated tin oxide which has a more structure of particle than the metastannic acid grade. It said that not only can be used in catalysis nut also can be used in the separation of radionuclides as an ion exchanger. [3]
Other
Tin oxide is not pure; it has small impurity in it. This certain impurity can give the range of tin oxide by based on the area of high specific surface, and the size of the particle. These characters make us easy to find the application in catalysis or gas sensor.
Metastannic acid is another hydrated tin oxide except alpha stannic acid that we were mentioned before. This acid has a very high specific surface area and a primary particulate particle size. It also helps to find the way of application for the production of ceramic pigments and catalysis.
