Boron oxide (2 B 0 3) was added in a weight ratio of component 5%
A glass containing a weight ratio is formed, a glass bottle of 50 ml capacity is blown as a glass product from the glass, and silyltetraisocyanate is contacted by a CVD method at a take-out tong, and a silica is used for heat treatment in a slow cooling furnace to prevent elution of alkali and the like. A coating was formed.

The amount was measured (method of measuring surface alkali by the Japanese Pharmacopoeia Method No. 2), and the consumption of sulfuric acid was 0.08 ml. Also, there was no clouding due to cloudiness on the surface.

The results show that the presence or absence of the silica coating containing the boron oxide component of the glass The amount of sulfuric acid consumed The amount of cloudiness (% Weight ratio) 1 / 50N (ml) 0 No 2.45 0 Yes 0.32 Slightly cloudy 0.5 No 2.31 0.5 Yes 0.30 Slightly cloudy 2.0 No 2.29 2.0 Yes 0.12 No clouding 5.0 No 2.06 5.0 Yes 0.08 No clouding 8.0 No 2.15 8.0 Yes 0.04 No clouding 10.0 No 2.20 10.0 Yes 0. 04 No fogging From these results, it can be seen that when the content of the boron oxide component in the glass composition is 2% by weight or less, the appearance of the silica coating by silyltetraisocyanate is cloudy and the effect of preventing elution of alkali and the like is stable. do not do. On the other hand, when the content of the boron oxide component in the glass composition is set to 10% by weight or more, the cost of raw materials such as boric acid increases, so the 10% by weight is the limit.
