On Wednesday March 23, 2016 at The Cathedral Basilica of St Augustine there was The Mass of Holy Chrism. The Celebrant was The Most Reverend Felipe Estevez, Bishop of St Augustine.
From Wikipedia a brief explanation of what Chrism is:
Chrism is essential for the Catholic Sacrament of Confirmation/Chrismation, and is prominently used in the sacraments of Baptism andHoly Orders. Those to be confirmed or chrismated, after receiving the laying on of hands, are anointed on the head by the bishop orpriest. In baptism, if the person baptized is not to be immediately confirmed or chrismated, the minister anoints them with chrism. Newly ordained priests are anointed with chrism on the palms of their hands, and newly ordained bishops receive an anointing of chrism on their foreheads. It is also used in the consecration of objects such as churches and altars.
Before the reforms of the Second Vatican Council, chrism had to be used to consecrate patens and chalices as well. The Sign of the Cross would be made with the chrism on the interior parts the chalice and paten where the Eucharist would rest; the Cross would then be smeared to cover the entire interior parts. The chalice and paten would need to be consecrated with the chrism again if they were re-gilded. This ritual could only be performed by a Bishop or a priest with the faculties to do so. According to the rubrics, a simple blessing suffices. However, it is still permitted that the bishop performs the consecration with chrism.
Chrism is made of olive oil and is scented with a sweet perfume, usually balsam. Under normal circumstances, chrism is consecrated by the bishop of the particular church in the presence of the presbyterium at the Mass of the Chrism, which takes place in the morning of Holy Thursday. The oil of catechumens and the oil of the sick are also blessed at this Mass.
These holy oils are usually stored in special vessels known as chrismaria and kept in a cabinet known as an ambry. When the oils are distributed to a priest for him to use in his ministry they are kept in a smaller vessel with three compartments, known as an "oil stock". There is also a type of oil stock that is shaped like a ring, to make the anointing easier. The "jewel" of the ring is a container with a removable lid.
The Holy Ampulla or Holy Ampoule (Sainte Ampoule in French) was a glass vial which, from its first recorded use by Pope Innocent II for the anointing of Louis VII in 1131 to the coronation of Louis XVI in 1774, held the or anointing oil for the coronation of the kings of France. Said to have been discovered by Hincmar the Archbishop of Reims when the sepulcher containing the body of Saint Remi was opened in the reign of Charles the Bald and identified with the baptism of Clovis I, the first Frankish king converted to Christianity; it was kept thereafter in the Abbey of Saint-Remi, Reims and brought with formality to the Cathedral of Notre-Dame, Reims at each coronation, where the emphasis was on the anointment rather than on the crowning. Some remains of the content of the ampoule, destroyed in 1793 by French revolutionaries, were placed in a new reliquary made in time for the coronation of Charles X and are kept since 1906 at the Archbishopric of Reims.
