The invention relates to a stabilized composition for coating glass containers, and to its method of use. The method involves the steps of heating the surface of a glass container to at least 427°C, and spraying the surface of the glass with a glass coating formulation comprising monoalkyltin trihalide and about .5 to 10 parts by weight per hundred parts monoal- kytin trihalide of a solubilizing material. The solubilizing material can be a solvent such as monohydric alcohols, represented by the formula ROH, where R is a C1-C8 straight or branched chain group and dihydric alcohols represented by the formula, HO-(CH2)m-OH, where m = 2 to 6. Other materials include glycol ethers represented by the formula R1(OCH2' CH2)nOH, where R' is a C1C3 group and n = 1 or 2 esters represented by the formula R2O2CR3, where R' is a C,C. straight or branched chain group, R4(OCH2CH2)swhere R' is a C1-C4 group, s = 1 or 2 branched chain group, R4(OCH2CH2)s where R' is a C,-C. group, s = 1 or 2, and R' is a C1C4 group or -CH2OH. Another class of materials is ketones having the formula R5COR', where R5 and R5 are C1-C6 straight, branched chain or cyclic groups. Other class of materials are ethers represented by the formula R7(OCH2CH2)OR5 where R' and R5 are C,-C. groups or-(CH2)P- where p=4or5,or-CH2CH2OCH2CH2-,and r = 0 - 4 and aldehydes represented by the formula R'COH, where R9 is C1-C3. Further class are anhydrides represented by the formula R10CO2COR11 where R10 and R" are a C1-C3 group and formamides represented by the formula R"R"NCOH where R12 and R" are a C1-C4 group, as well as acetals represented by the formula R14(CH2)qCH(OR15)2, where R" is H, OH,(CH3)2N, or(C2H5)2N, q = 0 or 1, and R15 is a C1-C2 group or a nitrile, R"CN where R" is a C1-C3 group. Mixtures of the various materials can be used. In every case the combination of the dopant and the glass coating material must have a flash point of at least 60°C. Among the preferred materials are the monohydric alcohols methanol, ethanol, propanol and isopropanol and mixtures thereof.
