Charcoal is one of the most important necessities required in Church during prayers, the union within the censor of charcoal and fire symbolizes the unity between the Divinity and Humanity of Christ, and is placed in censers representing the Virgin Mary.

Charcoal is one of the offerings in the church and thus included in the sacrifices litany. The priest prays on the altar the litany of sacrifices (Remember, O Lord, those who have brought unto you these gifts, those on whose behalf they have been brought, and those by whom they have been offered. Give them all the heavenly reward.)

Charcoal production steps: -
The theory of charcoal production is (burning wood in the absence of Oxygen)
First: charcoal is produced from wood trees and the best types of charcoal is made from wood of fruit trees, and this is the type used in church as it helps coal smell good with the incense grains.
Second: Wood is prepared, by cutting it in different sizes (based on thickness and not length).
Third: a suitable place is prepared in terms of ventilation and space to make a charcoal kiln.
Fourth: wood is arranged in the charcoal kiln, where thin wood is placed at the bottom and then the thicker, and so on… until we reach the thickest size. Then thick wood is placed first and then the thinner, until the end of the kiln, and thus the kiln is pyramid in shape.

Fifth: The Kiln is then covered with rice straw and sand is placed over it

Sixth: The Kiln is then put in fire in a certain way; during the presence of Bishop Metaous the Abbott of the monastery to bless the work upon starting
Seventh: Movement of the flare of wood is controlled through small openings which helps air to enter, and this attracts the flare towards the small openings, which are made in the upper third portion of the kiln.
Eighth: Once the burning of the upper third portion ends, we start dropping the flare from top to bottom (from the upper third to the lower two thirds) this is done through certain holes in the bottom of the kiln; the time it takes to burn the kiln depends on its size.
Ninth: The kiln is left several days while noticing the flare calms gradually
Tenth: The process of extinguishing starts, water extinguishing is the method used by the monastery. The charcoal is left until it completely dries from the water and

then the storage process begins.
