I have an electrical ceramic glass stove (pots are put on the glass). Am I allowed to use it on Pessach and how would I have to kasher it. Thanks and regards
I am copying the instuctions from the Star K website: at http://www.star-k.com/kashrus/kk-passover-kashering.htm#smoothtops THE STAR-K PESACH KITCHEN Rabbi Moshe Heinemann, Star-K Rabbinic Administrator Kashering a Glass, Corning, Halogen or Ceran electric smoothtop range for Pesach use is a bit complex. To kasher the burner area, clean well and turn on the elements until they glow. The burner area is now considered kosher for Pesach. However, the remaining area that does not get hot is not kashered. The manufacturers do not suggest covering this area as one would a porcelain or stainless steel top, as it may cause the glass to break. Real kosherization can be accomplished by holding a blow torch over the glass until it is hot enough to singe a piece of newspaper on contact with the glass. However, this too may cause the glass to shatter and is not recommended. As the area between the burners cannot practically be kashered, it would be wise to have a trivet on the open glass area to move pots onto. In addition, in order to use a large pot that extends beyond the designated cooking area, one should place a metal disc, approximately 1/8 of an inch thick, on the burner area to raise the Passover pots above the rest of the glass surface. (Caution: This disc should not extend beyond the designated cooking area.) This will also help in case a small pot boils over, sending a trickle of hot liquid that would serve as a connector from the Passover pot to the non-Passover stovetop. (Note: Cooking efficiency may be compromised when using a metal disc.) For gas stovetops with a glass surface, one may kasher the grates by putting them in the oven with a libbun kal (550°F for forty minutes). In most such models the grates cover the entire top of the stove and there should be no problem adjusting pots on the stovetop. Food which falls through the grates and touches the glass surface should not be used. For those models where the grates do not cover the entire cooktop surface, it would be wise to place a trivet on the open glass area to move pots onto, as no food or pots may come in direct contact with the non-kashered glass surface. Some gas cooktops have an electric warming area on the glasstop. This area would have to become red hot when turned on in order to kasher. Many of these warming areas do not get hot enough for kashering and may not be used on Pesach.
