Gilyon ha'Shas 16a DH Avdu Behu:
 Gemara 16b [line 8]:
1) [line 1] KLEI NESER - (a) utensils made from the crystals of alum (RASHI); (b) utensils stuck together with alum (ARUCH)
2) [line 2] MITAM'IN U'METAM'IN - they may become Tamei and may make the objects inside them Temei'im
3) [line 3] ACHOREIHEN - the inside of their stands
4) [line 7] YACHZERU L'TUM'ASAN YESHANAH
(b) The Gemara (16b) gives three reasons for his decree: (1) so that Mei Chatas (the water that contains the ashes of the Parah Adumah) not become obsolete. For example, a person owns a utensil which comes in contact with a dead body. It must be sprinkled with Mei Chatas on the third and seventh days of the Taharah process. He would rather pierce it, fix it, and be able to use his utensil on the same day that it became Tamei. (2) lest people pierce their utensils with a hole *less* than the required size to render them Tehorim, and mistakenly think that they have rendered them Tehorim. (3) lest people think that a utensil that becomes Tamei (through Tum'ah other than a dead body) can be immersed in a Mikvah and used immediately, without waiting for nightfall.
(c) The Gemara asks with regard to glassware, that even though they have been broken in the interim (which renders them Tehorim), why do they not receive their previous status of Tum'ah when they are rebuilt, as is the case with metal utensils?
5) [line 8] KLEI MATCHOS - The six types of metal utensils which are listed in the Torah (Bamidbar 31:22) are gold, silver, copper, iron, tin and lead. If they become Temei'im, they can be immersed in a Mikvah to make them Tehorim again. If they are pierced or broken and are no longer useful, they become Tehorim. If broken metal utensils that are Temei'im are rebuilt, they return to their previous status of Tum'ah.
6) [line 17] ACHISU BAH RABANAN TUM'AH - the Chachamim decreed that their previous Tum'ah should return to them
7) [line 2] NIR'EH TOCHO K'VARO - (a) since its inner surface is visible
from the outside, the outer surface has the same laws as the inner surface,
and *does* become Tamei, unlike the outer surface of earthenware utensils
8) [line 10] TZOREF - smith; smelter
11) [line 18] RATZFINHU MIRTZAF - he totally smashed them
13) [line 22] KLEI GELALIM - utensils made from animal dung (RASHI throughout Shas; here Rashi appears to translate Gelalim as marble). See Insights
14a) [line 28] KISHUR AVIM - when the clouds are gathered together before a
15) [line 34] BATZREI LEHU - there are less [than eighteen]
16) [line 35] BENOS KUSIM NIDOS ME'ARISASAN
(b) The Chachamim decreed that the daughters of the Kusim have the status of Nidos from birth. TOSFOS (Nidah 32a, DH Rebbi Meir) explains the disagreement of Rebbi Meir and Rebbi Yosi as to the nature of the decree. According to Rebbi Yosi, the Rabanan gave Benos Kusim the status of Nidos in order to prevent us from mingling with them. According to Rebbi Meir, the Rabanan gave them the status of Nidos from an early age because the Kusim did not accept the Torah Law that a one-day-old girl becomes a Nidah through a discharge of blood, and we suspect every Bas Kusi of having had a discharge of blood. See Insights to Nidah 31:2.
17) [line 36] MEVI'IN ES HA'TUM'AH
18) [line 37] B'OVI HA'MARDEI'A - the width of the handle of a plow, which has a circumference of a Tefach
