21b

{Shabbat 47a}
Rava said: When we were in the house of Rav Nachman, we would handle a brazier on account of its ashes, even if broken pieces of wood were lying upon it.

They learnt {in a brayta}: The sockets of a bed {into which the legs of a bed fitted. to prevent them from being rotted by the damp earth}, the legs of a bed, and the archer's tablets {Rashi: a small wooden plaque inserted in the bow upon which the arrow presses before it is released} may not be re-inserted, yet if one does re-insert [them], he is not liable [to a sin-offering], but it is forbidden to do so;

{Shabbat 47b}
nor must they be [tightly] fixed in, and if one does so, he is liable to a sin offering. Rabban Shimon ben Gamliel says: if it is loose, it is permitted.

At R. Hama's home there was a folding bed, which they used to put up on Yom Tov.
One of the Rabbis to Rav Chama {our gemara: Rava}: What is your view, that it is building from the side {that is, not done in its usual way}: granted that there is no Scriptural prohibition, yet it is Rabbinically forbidden?
He said to him: I am of the opinion of Rabban Shimon ben Gamliel, who says: if it is loose, it is permitted.
And so is the halacha.

{The Mishna had said:} "A VESSEL MAY BE PLACED UNDER A LAMP TO CATCH THE SPARKS":
But he nullifies the vessel of its readiness?
Rav Huna the son of Rav Yehoshua said: Sparks are intangible, and it is permitted to handle/move them, and so they do not nullify the readiness of the vessel?

"BUT ONE MUST NOT POUR WATER THEREIN, BECAUSE HE EXTINGUISHES [THEM]":
They learnt {in a brayta}: A vessel may be placed under a lamp on the Sabbath to catch the sparks, and one need not say, on erev Shabbat. But one must not pour water therein - on erev Shabbat, and one need not say, on Shabbat, because one brings the extinguisher near.

MISHNA:
WHEREIN MAY WE STORE [FOOD], AND WHEREIN MAY WE NOT STORE [IT]?
WE MAY NOT STORE [IT] IN PEAT, FOLIAGE, SALT, LIME, OR SAND, WHETHER MOIST OR DRY;
NOR IN STRAW, GRAPE-SKINS, SOFT FLOCKING OR HERBAGE, WHEN THEY ARE MOIST; BUT WE MAY STORE [FOOD] IN THEM WHEN THEY ARE DRY.

{Shabbat 49a}
WE MAY STORE [FOOD] IN, GARMENTS, PRODUCE, DOVES' WINGS, CARPENTERS' SAWDUST AND THOROUGHLY BEATEN HATCHELLED FLAX.
