1. When entering the Kodesh ha'Kodashim, the Kohen Gadol would hold the fire pan of coals in his right hand and the Ketores in a smaller vessel in his left hand.
2. Both the Kemitzah and the rest of the flour-offering must be present when the Kemitzah is burned in order to fulfill the Mitzvah of offering a flour-offering.
3. He may burn the Korban on the Mizbe'ach by making a condition that if the Korban is invalid (and may not be burned on the Mizbe'ach as a Korban), then it should be considered fuel for the fire of the Mizbe'ach, and not a Korban. The Rabanan argue that this is forbidden.
4. One is supposed to take his hand with the sides of his fingers facing downwards and the palm of his hand facing the mixture, and fill his fist with the mixture.
5. For example, if one were to have his palm on top of the mixture and dig his fingers downward into the mixture thereby filling up his hand, the Gemara concludes with a doubt ("Teiku") about whether this is a valid Kemitzah.
