بَوْرَقٌ
1.
, (JK, Mgh,) with fet-h to the ب (Mgh,) or بُورَقٌ., with damm, (K,) A certain, thing, or substance, that is put into dough, (JK, Mgh, TA,) and causes it to become inflated; (Mgh;) or into flour; (TA voce بُورَكٌ;) [or this is a particular kind thereof, as appears from what follows: according to Golius, nitrum and aphronitrum: but] it is of four kinds;
مَايءِىٌّ [or the water-kind], and جَبَلِىٌّ [or the mountain-kind], and أَرْمَنِىٌّ [or Armenian], and مِصْرِىٌّ [or Egyptian], which is the
نَطْرُون [q. v., i. e. natron]: (K:) the best thereof is the
ارمنى; and this is said to be meant by the term when it is used absolutely: this is called also
بورقُ الصَّاغَةِ [a term now applied to borax, as is بورق alone, and مِلْحُ
الصَّاغَةِ], because it polishes silver well [or because of its use in soldering]: the dust-coloured kind thereof is called
بورقُ الخَبَّازِينَ [the
بورق
of the bakers, or makers of bread]: the
نطرون
is the red kind thereof: and there is a kind thereof having an oily quality: and a kind consisting of thin butyraceous fragments; and this, if light and hard, is the
إِفْرِيقِى: and the best thereof is that which is produced in Egypt: (TA:) bruised, or powdered, the belly is smeared with it, near to a fire, and it expels worms: and moistened with honey or with oil of jasmine, the male organs of generation are anointed with it, for it is excellent for the venereal faculty. (K.)
