The company INGA stands for "Industria Nazionale Gessi e Affini" and was founded in the early fifties by the Sgambaro family.

It was one of the four Italian manufacturers producing chalk for school blackboards, an indispensable aid in education and entertainment for thousands of children and young people at the time. In addition to blackboard chalk, INGA produced "affini," which are other chalk products such as stucco, packaged and sold in powder or paste form. In the 60s and 70s, INGA also added decorative interior elements to its blackboard chalk production. This way, the INGA brand became one of the leading producers of original decorative stucco, such as rosettes, frames, and wall and ceiling cornices. These were very fashionable at the time, ordered and installed in homes as decorative elements.

Over the years, Inga gradually moved away from mass production to focus solely on creating artistic objects that reflect a passion for beauty, culture, and elegance. INGA transformed into a true art laboratory, where unique, refined, and personalized plasters are created for clients from all over the world.
