A caulking composition and method, particularly for hermetically sealing coke ovens and the like having high temperature requirements. The composition is adhesive to metal surfaces at elevated oven temperatures, elastic to accommodate expansion, warping, etc. and drys to a crushable powder by the conclusion of the oven cycle. The composition comprises, by weight, 19 to 23% of a high temperature silicone oil, preferably about 20% dimethyl polysiloxane 20 to 34% of a thermally conductive white metal oxide, preferably zinc oxide, 20 to 34% of an inert particulate filler material, such as whiting and 22 to 35% of a hydrated alkaline metal oxide, such as hydrated lime.
