Abstract
The chemical composition of bottle glass is consisted of Na2O-CaO-SiO2. However the cullet is mornally used in order to decrease the melting tsmperature. This induce the productivity of bottle and decreases the cost. The addition of plate glass decreases the Al2O3 content and in fluence the stone phenomenon and devitification in botle glass. Tus the Feldspar is added in order to increase the Al2O3 content when plate cullet was added in melting. The Tridymite crystal was observed over 7.5% Al2O3 contents, which shown as white crystal in appearance. It is Supposed that the Wollastonite Would be occurred in more over 7.5% Al2O3. This fad id well consised With the Litertctures.
병유리 파유리는 생산하고자 하는 제품과 같은 조성을 가지고 있어 아무리 투입해도 문제가 발생하지 않지만 수급에 문제가 발생하고 있어 예전에는 사용하지 않고 폐기하던 판상 파유리를 사용하고 있다. 그러나 현재 판상 파유리를 사용하면서 판상 파유리의 이질성 때문에 실투, Stone과 같은 많은 문제가 발생하고 있다. 이것의 원인은
