Does a poercelain tea kettle need to toveled with bracha? What about its cover?
The kettle and its cover should be toiveled, but not with a berachah.
Porcelain might have the halachah of cheres, clay, whereby it is exempt from tevilah. However, because of the method of porcelain production today, most poskim are stringent and obligate tevilah (seeing the porcelain utensil as being possibly similar to glass), but without a berachah.
