The contacting can be performed by applying the composition to the surface of the glass or the ceramic frit using an application apparatus. In one embodiment, the composition further comprises a lubricant. In another embodiment, the composition further comprises one or more ethoxylated alcohols. In another embodiment, the composition further comprises one or more fragrances. ## Claims ### Claim 1 A method comprising contacting a composition comprising i) alumina particles having a particle size of about 1 to about 40 microns and a Mohs hardness of about 9.0 to about 9.5; ii) one or more alkyl sulphates; iii) one or more thickeners; and iv) water with a glass surface or a ceramic enamel frit disposed on a glass surface. ### Claim 2 (depends on 1) A method according to claim 1 wherein the contacting is performed by applying the composition to the surface of the ceramic frit using an application apparatus. ### Claim 3 (canceled) ### Claim 4 (depends on 2) A method according to claim 2 wherein the composition comprises: i) about 10 to about 80 percent by weight of alumina particles; ii) about 0.1 to about 5 percent by weight of one or more alkyl sulphates; iii) about 1 to about 10 percent by weight of one or more thickeners; and iv) about 15 to about 80 percent by weight of water. ### Claim 5 (depends on 4) A method according to claim 4 wherein the composition further comprises a lubricant. ### Claim 6 (depends on 5) A method according to claim 5 wherein the lubricant is present in an amount of about 0 to about 25 percent by weight. ### Claim 7 (canceled) ### Claim 8 (depends on 5) A method according to claim 5 wherein the composition further comprises one or more ethoxylated alcohols. ### Claim 9 (depends on 8) A method according to claim 8 wherein the one or more ethoxylated alcohols are present in an amount of about 0 to about 0.1 percent by weight. ### Claim 10 (depends on 8) A method according to claim 8 wherein the composition further comprises one or more fragrances. ### Claim 11 (depends on 10) A method according to claim 10 wherein one or more fragrances are present in an amount of about 0 to about 0.1 percent by weight. ### Claim 12 (canceled) ### Claim 13 (depends on 1) A method according to claim 1 wherein the one or more thickeners comprises cellulose, a derivative of cellulose, clay or an acrylic polymer. ### Claim 14 (canceled) ### Claim 15 (depends on 1) A method according to claim 1 which further comprises the step of cleaning the surface of the ceramic frit. ### Claim 16 (depends on 15) A method according to claim 15 wherein the cleaner is a mixture of water and alcohols. ### Claim 17 (depends on 14) A method according to claim 14 wherein the cleaning step is performed after application of the composition containing alumina particles. ### Claim 18 (depends on 15) A method according to claim 15 wherein the method further comprises applying a glass primer system to the surface of the ceramic frit after applying the composition containing alumina particles. ### Claim 19 (depends on 15) A method according to claim 15 wherein the method further comprises applying a glass primer system to the surface of the ceramic frit after applying the composition containing alumina particles and the cleaning step. ### Claim 20 (depends on 1) A method according to claim 1 which further comprises applying an adhesive to the ceramic frit surface of the glass and contacting the glass with a second substrate wherein the adhesive is disposed between the glass and the second substrate. ### Claim 21 (depends on 20) A method according to claim 20 wherein the second substrate is a flange of a window frame. ### Claim 22 (depends on 21) A method according to claim 21 wherein the second substrate is the flange of a window for an automobile. ### Claim 23 A method of replacing a window in a structure which comprises a) removing the old window from the window frame; b) applying to the surface of a ceramic enamel frit disposed on the surface of a replacement glass window a composition comprising i) alumina particles having a particle size of about 1 to about 40 microns and a Mohs hardness of about 9.0 to about 9.5; ii) one or more alkyl sulphate; iii) one or more thickeners; and iv) water; c) optionally, cleaning the surface of the ceramic frit with a cleaner; d) optionally, applying a primer system to the surface of the ceramic frit; e) applying a bead of adhesive to the glass window around the periphery of the ceramic frit; f) applying an activator system to the old adhesive remaining on a flange of the window frame; g) contacting the window with the window frame such that the adhesive is disposed between the window and the flange and that the adhesive forms a seal between the window and the window frame.
