The article has a body of porous aerosol containment material. An annular first body of smokable material is located around the body of porous aerosol containment material. There is also provided apparatus for heating smokable material having a first heater extending along an axis and a second heater spaced from and at least partially surrounding the first heater. A method of manufacturing an article for use with an apparatus is also disclosed in which an assembly having porous aerosol containment material on a first layer of smokable material is provided and rolled so the first layer of smokable material becomes an annular body of smokable material located around the porous aerosol containment material. ## Claims ### Claim 1 An article for use with apparatus for heating smokable material to volatilize at least one component of the smokable material, the article comprising: a body of porous aerosol containment material; an annular first body of smokable material located around the body of porous aerosol containment material; and an annular second body of thermally-conductive material located around and in contact with the annular first body of smokable material, the annular second body of thermally-conductive material comprising a metal foil. ### Claim 2 (depends on 1) An article according to claim 1, wherein the annular first body of smokable material is in contact with the body of porous aerosol containment material. ### Claim 3 (depends on 2) An article according to claim 2, wherein the body of porous aerosol containment material is annular. ### Claim 4 (depends on 3) An article according to claim 3, wherein the body of porous aerosol containment material fills a space that is surrounded by the annular first body of smokable material. ### Claim 5 (depends on 3) An article according to claim 3, wherein the body of porous aerosol containment material is located around an air gap of the article. ### Claim 6 (depends on 1) An article according to claim 1, comprising a second body of smokable material, wherein the body of porous aerosol containment material is located around the second body of smokable material. ### Claim 7 (depends on 6) An article according to claim 6, wherein the second body of smokable material is annular. ### Claim 8 (depends on 7) An article according to claim 7, comprising an annular first body of thermally-conductive material, wherein the second body of smokable material is located around the annular first body of thermally-conductive material. ### Claim 9 (depends on 6) An article according to claim 6, wherein the smokable material of the annular first body of smokable material has a form or chemical composition that differs from the form or chemical composition, respectively, of the smokable material of the second body of smokable material. ### Claim 10 (depends on 9) An article according to claim 9, wherein the smokable material of one of the annular first body of smokable material or the second body of smokable material includes an aerosol forming agent, and the smokable material of the other of the annular first body of smokable material or the second body of smokable material is free or substantially free of the aerosol forming agent. ### Claim 11 A method of manufacturing an article for use with apparatus for heating smokable material to volatilize at least one component of the smokable material, the method comprising: providing an assembly comprising porous aerosol containment material on a first layer of smokable material, and a second layer of thermally-conductive material comprising a metal foil, the first layer of smokable material being on the second layer of thermally-conductive material; and rolling the assembly so that the first layer of smokable material becomes an annular first body of smokable material located around the porous aerosol containment material and so that the second layer of thermally-conductive material becomes an annular second body of thermally-conductive material located around and in contact with the annular first body of smokable material. ### Claim 12 (depends on 11) A method according to claim 11, wherein the rolling comprises rolling the assembly so that the porous aerosol containment material becomes an annular body of porous aerosol containment material which is arranged to be located around an air gap of the article. ### Claim 13 (depends on 11) A method according to claim 11, wherein the assembly comprises a second layer of smokable material on the porous aerosol containment material. ### Claim 14 (depends on 13) A method according to claim 13, wherein the smokable material of the first layer of smokable material has a form or chemical composition that differs from the form or chemical composition, respectively, of the smokable material of the second layer of smokable material. ### Claim 15 A kit comprising: an article for use with apparatus for heating smokable material to volatilize at least one component of the smokable material, the article comprising a body of porous aerosol containment material, an annular first body of smokable material located around the body of porous aerosol containment material, and an annular second body of thermally-conductive material located around and in contact with the annular first body of smokable material, the annular second body of thermally-conductive material comprising a metal foil; and apparatus for heating the smokable material of the article to volatilize at least one component of the smokable material, wherein the apparatus has an interface and the article is for co-operating with the interface of the apparatus. ### Claim 16 (depends on 8) An article according to claim 8, wherein the annular first body of thermally-conductive material comprises a metal foil.
