Patent ID: 8034732

Claim:
An antimicrobial glass comprising: a tabular antimicrobial glass comprising a glass composition and silver oxide capable of exerting an antimicrobial effect by releasing silver ions from the silver oxide, wherein the maximum diameter (t 1 ) of the antimicrobial glass is adjusted within a range of 3 to 30 mm and, an inorganic coloring agent as a compounded component, wherein an addition amount of the inorganic coloring agent is adjusted to a value within the range of 0.001 to 0.5% by weight relative to a total amount of the antimicrobial glass, wherein the inorganic coloring agent is cobalt oxide, wherein an amount of the silver ions eluted from the silver oxide is adjusted to a value within a range of 0.01 to 0.45 mg/(g·24 hrs), and wherein a ratio expressed by C1/C2 is in a range of 0.0006 to 3, where C1 is an amount of the inorganic coloring agent and C2 is an amount of the silver oxide relative to the total amount of the antimicrobial glass.
