水浴(yu)鍋就是(shi)使用水(shui)(shui)作(zuo)為熱(re)浴物質的(de)熱(re)浴方法(fa)。由于水(shui)(shui)溫在(zai)標準大(da)(da)氣壓下，最高(gao)為100℃，所(suo)以(yi)水(shui)(shui)浴最高(gao)溫度為100℃。應用水(shui)(shui)浴處理容(rong)器產品(pin)的(de)方法(fa)是(shi)：將需(xu)水(shui)(shui)浴的(de)容(rong)器浸沒在(zai)盛有水(shui)(shui)的(de)較(jiao)大(da)(da)容(rong)器中(zhong)，需(xu)水(shui)(shui)浴的(de)容(rong)器不(bu)得與較(jiao)大(da)(da)容(rong)器直接接觸，再將較(jiao)大(da)(da)容(rong)器置于熱(re)源上加熱(re)，至(zhi)適(shi)當溫度時停止加熱(re)，待冷(leng)卻后取出水(shui)(shui)浴容(rong)器即(ji)可。 

油浴鍋就(jiu)是使用油(you)(you)(you)(you)作為熱浴物質的(de)熱浴方法。常用的(de)油(you)(you)(you)(you)有豆油(you)(you)(you)(you)、棉籽油(you)(you)(you)(you)等。油(you)(you)(you)(you)浴最高溫度比(bi)水浴高，一般在100℃－250℃之間。油(you)(you)(you)(you)浴操(cao)作方法與水浴相同，不過進(jin)行油(you)(you)(you)(you)浴尤其要操(cao)作謹慎(shen)，防(fang)止(zhi)油(you)(you)(you)(you)外溢或油(you)(you)(you)(you)浴升(sheng)溫過高，引起失火。

溫(wen)(wen)度(du)區別：水浴溫(wen)(wen)度(du)0-100，油浴溫(wen)(wen)度(du)100-260。

加(jia)熱(re)(re)(re)(re)過程：加(jia)熱(re)(re)(re)(re)時，待加(jia)熱(re)(re)(re)(re)的(de)物(wu)(wu)質通常(chang)置(zhi)于(yu)容(rong)(rong)(rong)器(qi)(qi)(qi)內(nei)，容(rong)(rong)(rong)器(qi)(qi)(qi)置(zhi)于(yu)熱(re)(re)(re)(re)源上，有(you)些容(rong)(rong)(rong)器(qi)(qi)(qi)，如玻璃容(rong)(rong)(rong)器(qi)(qi)(qi)和陶瓷容(rong)(rong)(rong)器(qi)(qi)(qi)，若直(zhi)接置(zhi)于(yu)熱(re)(re)(re)(re)源上，則往往因受熱(re)(re)(re)(re)不(bu)均(jun)(jun)(jun)，溫升(sheng)過快(kuai)，產生炸裂，或(huo)因熱(re)(re)(re)(re)傳遞不(bu)良(liang)，使加(jia)熱(re)(re)(re)(re)物(wu)(wu)質受熱(re)(re)(re)(re)不(bu)均(jun)(jun)(jun)勻。為此，對(dui)進入實(shi)驗(yan)室(shi)的(de)加(jia)熱(re)(re)(re)(re)容(rong)(rong)(rong)器(qi)(qi)(qi)產品應(ying)進行熱(re)(re)(re)(re)浴(yu)處理。所謂熱(re)(re)(re)(re)浴(yu)，是將(jiang)容(rong)(rong)(rong)器(qi)(qi)(qi)置(zhi)于(yu)熱(re)(re)(re)(re)浴(yu)物(wu)(wu)質內(nei)，讓熱(re)(re)(re)(re)浴(yu)物(wu)(wu)質的(de)溫度緩慢升(sheng)高到一定程度，再讓其緩慢冷卻，從而(er)達到改善容(rong)(rong)(rong)器(qi)(qi)(qi)熱(re)(re)(re)(re)傳遞性能(neng)，使容(rong)(rong)(rong)器(qi)(qi)(qi)質底均(jun)(jun)(jun)勻的(de)方(fang)法(fa)。在實(shi)驗(yan)室(shi)常(chang)用(yong)的(de)熱(re)(re)(re)(re)浴(yu)方(fang)法(fa)有(you)水浴(yu)、油浴(yu)、沙浴(yu)等。
