In a LiO&#x2014;AlO&#x2014;SiObased crystallized glass using SnOas a substitute fining agent for AsOor SbO, a crystallized glass having less yellow coloration is provided at low costs. The glass is a LiO&#x2014;AlO&#x2014;SiObased crystallized glass comprising from 0.01 to 0.9% of SnOin terms of % by mass and having a content of each of AsOand SbOof 1,000 ppm or less as a glass composition, which has a VOcontent of from 0.08 to 15 ppm in the glass composition.

[object Object]

An object of the present invention is to provide a LiO&#x2014;AlO&#x2014;SiObased crystallized glass with excellent bubble quality even without using AsOor SbOas a fining agent and a method for producing the same. The LiO&#x2014;AlO&#x2014;SiObased crystallized glass of the present invention is a LiO&#x2014;AlO&#x2014;SiObased crystallized glass which does not substantially comprise AsOand SbOand comprises at least one of Cl, CeOand SnO, and has a S content of not more than 10 ppm in terms of SO.

Provided is a LiO&#x2014;AlO&#x2014;SiO-based crystallized glass, comprising, as a composition in terms of mass %, 55 to 75% of SiO, 20.5 to 27% of AlO, 2% or more of LiO, 1.5 to 3% of TiO, 3.8 to 5% of TiO+ZrO, and 0.1 to 0.5% of SnO, and satisfying the relationships of 3.7&#x2266;LiO+0.741MgO+0.367ZnO&#x2266;4.5 and SrO+1.847CaO&#x2266;0.5.

A glass manufacturing container includes a container body and an electron donor. The container body is made of a precious metal or an alloy containing a precious metal and has an inner surface to be brought into contact with molten glass and an outer surface kept from contact with molten glass. The electron donor is electrically connected to the outer surface of the container body. The electron donor is made of an electron donating material capable of donating electrons to the container body at operating temperatures.
