Cam vazo tavlama i\u015fleminin b\u00fcy\u00fck bir k\u0131sm\u0131, temelde, \u00fcr\u00fcn\u00fcn oda s\u0131cakl\u0131\u011f\u0131na ula\u015fmadan \u00f6nce i\u00e7 gerilimlerinin giderilmesi yoluyla yeni geli\u015ftirilen cam\u0131 stabilize eden kontroll\u00fc bir \u0131s\u0131l i\u015flem s\u00fcrecidir.

Normal soda-kire\u00e7 cam\u0131 (tipik olarak -74 silikon dioksit (SiO2), -15 sodyum oksit (Na2O) ve %8-10 kalsiyum oksit (CaO) i\u00e7erir) durumunda, tavlama s\u0131cakl\u0131\u011f\u0131 normalde 515\u00b0C ile 565\u00b0C aras\u0131ndad\u0131r. Bu noktada cam, \u015feklini koruyacak kadar sert, ancak atomik yap\u0131n\u0131n kademeli olarak yeniden d\u00fczenlenmesine ve gerilimin giderilmesine izin verecek kadar da yumu\u015fakt\u0131r.<\/p>
