    Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing optical glass to prevent the deterioration of a burner used for synthesis of glass particulates composing the optical glass and to obtain the optical glass of stable quality.
    SOLUTION: The optical glass of ≤0.005 piece/cm
    3 per unit volume in the number of residual air bubbles above 0.3 mm. The method for manufacturing a porous body comprises controlling the end face temperature of the burner 10 for glass synthesis by regulating the velocity of flow of combustible gas or combustion supporting gas during the deposition of the glass particulates. The end face temperature of the burner 10 for glass synthesis is regulated to ≤900°C. When the velocity of flow of the combustible gas is defined as vH, the velocity of flow of the combustion supporting gas as vO and the relation therebetween as vH=vOxa, a≤0.2 is set. When the velocity of flow of the combustible gas is defined as VH and the velocity of flow of the combustion supporting gas as VO 0.1≤b≤0.8 is set in the relation therebetween: VO=VH×b.
