Due to the Torah injunction not to eat ''chametz'' (leaven) during Passover,<ref name="bibleverse||Exodus|12:15|HE"/> observant families typically own complete sets of serving dishes, glassware and silverware (and in some cases, even separate dishwashers and sinks) which have never come into contact with ''chametz'', for use only during Passover. Under certain circumstances, some ''chametz'' utensils can be immersed in boiling water (''[[Hagalah|hagalat keilim]]'') to purge them of any traces of ''chametz'' that may have accumulated during the year. Many [[Sephardi Jews|Sephardic]] families thoroughly wash their year-round glassware and then use it for Passover, as the Sephardic position is that [[glass]] does not absorb enough traces of food to present a problem. Similarly, ovens may be used for Passover either by setting the self-cleaning function to the highest degree for a certain period, or by applying a [[blow torch]] to the interior until the oven glows red hot (a process called ''libun gamur'').<ref name="WSJblowtorch">{{Cite news |last= Lagnado |first= Lucette |title= As Passover Nears, These Rabbis Are Getting Out Their Blowtorches |page= A1 |newspaper= The Wall Street Journal |location= New York |date= April 18, 2011 |url= https://www.wsj.com/articles/SB10001424052748704628404576264751651607740 |access-date= August 8, 2017 |archive-date= August 25, 2017 |archive-url= https://web.archive.org/web/20170825112734/https://www.wsj.com/articles/SB10001424052748704628404576264751651607740 |url-status= live }}</ref>
