   DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
   The present invention will be described in detail by way of a preferred embodiment with reference to accompanying drawings. 
   The present invention forms screw-like projection towards the inner side of the ceramic bottle at the time of ceramic bottle production. When it pertains to plastic cork, screw-like projection is formed towards the outer side so that plastic cork can be used to air-tight the entrance of the ceramic bottle. 
   The present invention results from the following process; installation of medium for combination at the lower part of funnel-shaped plaster framework&#39;s main entrance; installation of screw pipe where screw-like projection is formed, onto aforementioned medium for combination; then production of ceramic bottle so that aforementioned screw pipe is situated at the entrance of ceramic bottle; undergo plasticity process while screw pipe is inserted onto produced entrance of ceramic bottle so that screw-like projection is formed from the inner side of ceramic bottle&#39;s entrance. The present invention enables the air-tightening of ceramic bottle&#39;s entrance with plastic cork by using screw-like projection. 
   The present invention formed screw-like projection ( 11 ) at the entrance ( 6 ) of ceramic bottle ( 1 ), produced with slip casting method so that plastic cork ( 16 ), formed with screw-like projection ( 15 ), can air-tight the entrance ( 6 ) of the ceramic bottle ( 1 ) by using the formed plastic cork ( 16 ) in the form of tightening the screw. 
   screw-like projection ( 11 ) is formed at the inner side of entrance ( 6 ) of the present invention&#39;s ceramic bottle ( 1 ), and screw-like projection ( 15 ) is formed on the cork ( 16 ) that blocks the entrance ( 6 ) of the aforementioned ceramic bottle ( 1 ) to block the entrance ( 6 ) of the ceramic bottle ( 1 ) by using plastic cork ( 16 ) through the combination of screw-like projection ( 11 ) ( 15 ). 
   Here, screw-like projection ( 11 ), formed on ceramic bottle ( 1 ), and the screw-like projection ( 15 ) of the plastic cork ( 16 ) are combined or such combination is removed when they are turned. Air-tightening is realized when plastic cork ( 16 ) is blocked. When the air-tightening of ceramic bottle ( 1 ) and plastic cork ( 16 ) is doubtful, and then install silicon packing ( 17 ) at the lower part of the plastic cork ( 16 ) so that silicon packing ( 17 ) is situated between the ceramic bottle ( 1 ) and plastic cork ( 16 ) to ensure impeccable air-tightening. 
   The production method of ceramic for plastic cork for the present invention is comprised of the following processes; process of combining screw pipe ( 14 ), installed at the lower part of the funnel-shaped plaster framework ( 5 )&#39;s main entrance ( 4 ) with screw pipe ( 14 ); process of inserting slip by placing funnel-shaped plaster framework ( 5 ), combined with aforementioned screw pipe ( 14 ), on the upper part of the plaster framework ( 2 ) ( 3 ); process of pouring slip when the thickness of ceramic bottle ( 1 ) is formed between the plaster framework ( 2 ) ( 3 ) and screw pipe ( 14 ); process of separating plaster framework ( 2 ) ( 3 ) and funnel-shaped plaster framework ( 5 ) when aforementioned ceramic bottle ( 1 ) hardens so that screw pipe ( 14 ) is inserted into the entrance ( 6 ) of the ceramic bottle ( 1 ); and the process of forming screw-like projection ( 11 ) at the entrance ( 6 ) of the ceramic bottle ( 1 ) by undergoing plasticity process for the ceramic bottle ( 1 ) where screw pipe ( 14 ) is inserted. 
   When it pertains to funnel-shaped plaster framework ( 5 ), funnel-shaped main entrance ( 4 ) is formed at the inside, and installation of medium for combination takes place at the lower part of the aforementioned main entrance ( 4 ). Formation of aforementioned medium for combination is based on the combination pipe ( 12 ) or combination projection ( 12 ). When combination pipe ( 12 ) is installed at the funnel-shaped plaster framework ( 5 ), screw pipe ( 14 ) is combined by being externally inserted into the combination pipe ( 12 ), and when combination projection ( 13 ) is installed into funnel-shaped plaster framework ( 5 ), the combination takes place by being inserted into the combination groove ( 18 ), formed on screw pipe ( 14 ). 
   The present invention&#39;s medium for combination may take place by using other mediums besides the aforementioned combination pipe ( 12 ) or combination projection ( 13 ), but these shall include a structure whereby screw pipe ( 14 ) can be attached. 
   The present invention&#39;s screw pipe ( 14 ) is made with materials such as plastic, resin and starch that can be destroyed by fire when heat is exerted. Screw pipe ( 14 ) shall be destroyed by fire during the process of incineration for ceramic bottle ( 1 ). 
   The following is the production method for the ceramic bottle ( 1 ) of the present invention. 
   First of all, the process of assembling plaster framework ( 2 ) ( 3 ) is comparable to that of existing slip casting. In the present invention, medium for combination is installed at the lower part of the funnel-shaped plaster framework ( 5 ) to combine with screw pipe ( 14 ). 
   When combination pipe ( 12 ) is formed at the lower part of the funnel-shaped plaster framework ( 5 ), combine by circulating with screw pipe ( 14 ) attached on. When combination projection ( 13 ) is formed at the lower part of the funnel-shaped plaster framework ( 5 ), then combine by circulating after inserting into the combination groove ( 18 ) of the screw pipe ( 14 ). 
   When screw pipe ( 14 ) is combined with the lower part of the funnel-shaped plaster framework ( 5 ) using medium for combination, install funnel-shaped plaster framework ( 5 ) in a way so that the aforementioned screw pipe ( 14 ) is situated at the inside of plaster framework ( 2 ) ( 3 ). Then, insert slip into the inner part of the plaster framework ( 2 ) ( 3 ) through the main entrance ( 4 ) of the aforementioned funnel-shaped plaster framework ( 5 ). 
   When slip is filled inside the plaster framework ( 2 ) ( 3 ) and funnel-shaped plaster framework ( 5 ), then ceramic bottle ( 1 ) of specific thickness shall be formed after specific time lapses by. When the time needed for the formation of desired ceramic bottle ( 1 )&#39;s thickness at the interior of the plaster framework ( 2 ) ( 3 ) lapses by, discharge slip, filled in the plaster framework ( 2 ) ( 3 ) by lifting plaster framework ( 2 ) ( 3 ) up side down. 
   When the slip, filled in the plaster framework ( 2 ) ( 3 ), is discharged, then return plaster framework ( 2 ) ( 3 ) into its original position. Then, remove funnel-shaped plaster framework ( 5 )&#39;s medium for combination to separate screw pipe ( 14 ), and lift out funnel-shaped plaster framework ( 5 ) to separate into plaster framework ( 2 ) ( 3 ) again. 
   Then, ceramic bottle ( 1 ) is formed at a state whereby screw pipe ( 14 ) is inserted into the entrance ( 6 ), which leads to the birth of complete ceramic bottle ( 1 ) after going through the drying and plasticity processes. 
   Plasticity process is undergone at a state whereby screw pipe ( 14 ) is inserted into the entrance ( 6 ) of aforementioned ceramic bottle so that screw pipe ( 14 ) maybe completed destroyed by fire during the above mentioned process due to heat. 
   Then, screw-like projection ( 11 ) is formed at the entrance ( 6 ) of ceramic bottle ( 1 ), which coincides with the external view of the screw pipe ( 14 ), and which in turn is produced at a specific, consistent measurement since screw pipe ( 14 ) is produced in a consistent manner. 
   When the ceramic bottle ( 1 ), formed with screw-like projection ( 11 ) at the entrance ( 6 ), completed, the screw-like projection ( 15 ) is formed on the plastic cork ( 16 ) to ensure combination among screw-like projections ( 11 ) ( 15 ). Therefore, entrance ( 6 ) of ceramic bottle ( 1 ) is blocked with plastic cork ( 16 ). 
   Here, air-tightening of ceramic bottle ( 1 ) with plastic cork ( 16 ) is made impeccable. However, when doubtful, use silicon packing ( 17 ) to air-tight with plastic cork ( 16 ) from the upper part of the ceramic bottle ( 1 ) to ensure a more complete air-tightening. As mentioned above, the ability to tighten the entrance ( 6 ) of ceramic bottle ( 1 ) by using plastic cork ( 16 ) in a form of screwing in by forming screw-like projection ( 11 ) is not limited to the ceramic bottle ( 1 ). Application can be made on the ceramic container with wide entrance and other products such as ceramic container and related products.
