Long before whiteboards, beamers and laptops entered modern school classrooms, teachers relied on the humble, dusty, sometimes screechy blackboard chalk -- a material that has created a Jordanian business success story.
Chemical engineer Salah Aloqbi remembers sitting on a bus in Amman in 1995 when he hit on the idea that would lead him to create his company. More than two decades later it boasts 150 staff, with exports to more than 100 countries.
Chalk, a white, soft limestone, was formed aeons ago when the shells of tiny marine creatures were compressed on the sea floor -- and the landlocked Middle Eastern desert country of Jordan is blessed with vast deposits.
"I was returning from work at the Jordan Carbonate Company when I heard a radio interview saying that the calcium carbonate produced by the company is used in various industries in Jordan -- except the chalk industry."
Aloqbi pondered how to make blackboard chalk, which was until then wholly imported, to gain extra value from the calcium carbonate that is also used to produce white cement, make soils less acidic, and toothpaste more abrasive.
"But the chalk that we produced at that time was no longer used around the world, so we moved to produce dustless medical chalk," he said, referring to a carbonate-based type with larger particles.
- The right stuff -
Jordan has a near endless supply of the raw material, with the ministry of energy and mineral resources estimating the country's "assets of limestone exceed 1.3 billion metric tons".
Limestone is the common form of calcium carbonate CaCO3, the main ingredient for chalk.
The chalk pieces come in a wide palette of colours and are used for art and play around the world.
The firm has also branched out into coloured crayons and modelling clay, and is the country's only producer of chalk sticks.
Today, the company sits on a 7,500 square metre plot and offers sought-after jobs in a country where the unemployment rate soared to 25 percent last year, about the same as the poverty rate.
At first, she said, "it was difficult for parents to allow females to work ... But today they have no problem with that, especially because the factory is safe, not like other workplaces."
Another colleague, Alaa Aloqbi, 33, said "the factory has provided job opportunities at a time when life became difficult".
