With the observation of the outward appearances, it can be known roughly that if the sample was added with adulterations. Since the beeswax dissolves in the benzene but the adulterations, such as gypsum, starch and so on do not, these can be determined. By the verification of acid value and alcohol dissolve ability, the acid or non acid added can be determined. By the change of saponification value, the ester or non ester added can be determined. By the carbonification degree in the concentrated sulphuric acid, the mineral wax, such as paraffin wax added can be determined.

通过样品外观的观察初步定性是否掺有杂质；利用纯蜂蜡在苯中溶解，而掺入的石膏、面粉和淀粉等杂质在苯中不溶而定量鉴定这类杂质；由酸值变化和乙醇溶解物的量，测定掺入的硬脂酸等酸性物质或其它的非酸性物质；由皂化值变化，定量测定掺入的动物脂等酯类物质或其它的非酯类物质；根据蜂蜡中的烃类在浓硫酸中可被炭化，加入的石蜡等矿物蜡不被炭化来测定此类掺杂物。
