The lyrics of the song are emotional and convey a sense of struggle. They express the singer’s feelings of having to face numerous challenges and the realization that they could have been living a happier life. Reportedly, Jessie J is going to perform the song live first to gauge if she has a hit on her hands. Apparently, her team thinks “Heaven Bound” is a perfect comeback track. The song has also made Jessie really proud because it is a collaboration with Claude. The singer has been working hard on a new album and is proud of everything she has created in the studio so far. Still, it seems “Heaven Bound” is truly special to her.

It was announced that Jessie J was currently working on a documentary that will focus on her journey back to music, as well as her journey to becoming a mother. The documentary is set to cover a range of topics, including Jessie’s experiences with pregnancy, health issues, heartbreak, and her love life. The documentary will also touch upon her fall from public favor, as well as her plans for a comeback.

According to a source, Jessie was determined to continue her career despite her pregnancy, and the documentary will provide a behind-the-scenes look at her efforts to do so. Jessie’s upcoming album, which will be her first since 2018’s R.O.S.E. and the holiday album This Christmas Day, is highly anticipated by her fans.

Jessie recently performed an acoustic set at London’s O2 Shepherd’s Bush Empire and had a TV crew with her. In addition to the new album, a world tour is being prepared as a follow-up in 2024. The singer, who is with the basketball player Chanan Colman, announced her pregnancy this January, 13 months after suffering a devastating loss of pregnancy.

A ceramic vessel was recently found in Jerusalem that contained chemical residues that seem likely to have originated from explosives. The vessel was dated to the 12th century and represented a sort of medieval hand grenade that was likely used by Saladin’s forces at the Siege of Jerusalem in 1187. The recent discovery has practically supported claims that hand-held explosive devices were, in fact, used during the Crusades. Apparently, the recipe never reached beyond North Africa and the Middle East.

Other Ceramic Vessels from the Era of the Crusades Had Other Purposes

While conical and spherical ceramic vessels from the 9th to the 15th century and the era of the Crusades are often discovered across the Middle East, their uses are usually debated among scholars. Some speculations include that they held mercury for some arguable medicinal purposes of the time and mining, as well as scented oils.

According to Dr. Carney Matheson of Griffith University, the residues inside four of the recently discovered vessels were all found in Jerusalem’s Armenian Gardens. They were found in a layer dating to the 11th and 12th centuries. Matheson, ceramicist Rob Mason, and other co-authors of the research and paper have found different chemicals in those vessels, showing that they had diverse uses.

One of the Vessels from the Crusades Contained a Flammable Mixture

One of the recently found vessels, which was called sherd 737, was probably the most significant. It contained a flammable mixture that could have been used as an explosive. It wasn’t an import from China, where gunpowder was in use since the ninth century, but rather made by local manufacturers at the time, and was possibly a unique invention. Sherd 737 contained traces of mercury, sulfur, magnesium, and nitrates, showing a sophisticated explosive device. It was very different from Chinese black powder and used magnesium that came from the Dead Sea.

Dr. Carney Matheson pointed out that these vessels have reportedly been used during the time of the Crusades. It was known that the grenades were thrown against Crusader strongholds and produced loud noises and bright flashes of light. Matheson added that researchers have proposed the vessels were used as grenades that used Chinese black powder. It has also been proposed that black powder might have been introduced to the Middle East as early as the 9th to 11th centuries. Still, the Arabic texts from the time refer to various recipes for explosives that have proven hard to replicate.

Matheson believes these vessels were used as hand grenades because they were sealed within ceramic and fired at temperatures of up to 2,400ºF, so pressure could build up inside and explode into fragments.
