The alchemist has no choice but to prepare either a large amount of gold and silver so that it is available to him when he needs it or only enough for a short while. pg 355
Daily Halacha
Shabbos begins with the lighting of candles only for the lady of the house who is lighting the Shabbos candles. All other household members, including any girls in the house who do not light candles, are not obligated to begin observing Shabbos until sunset or at a designated earlier time when the entire community "accepts Shabbos."
