In the medieval period, white chalk played a significant role in various aspects of daily life. From practical applications to artistic endeavours, chalk was a versatile and valuable material. Here’s a closer look at the medieval use of chalk.

Slate and Paper

Chalk was also utilised in the creation of illuminated manuscripts, which were intricate and richly decorated handwritten books. Scribes would apply it as a preparatory layer on the parchment to create a smooth surface for writing and painting.

It also helped prevent ink from bleeding into the fibres and allowed for finer details in the illustrations. Early paper was expensive so mistakes were costly.

Chalk served as a versatile artistic medium in the medieval period. Artists, particularly those working on walls or murals, used chalk as a preliminary sketching tool. They would outline the desired design on the surface before applying pigments or frescoes. The soft texture of chalk allowed for easy corrections and modifications.

Chalk in Medieval Trades

Chalk was commonly used by medieval tailors and seamstresses. They would mark patterns and measurements on fabrics using chalk, enabling precise cutting and stitching. The chalk markings were temporary and could be easily removed or washed away once the sewing was complete. The same method is still used by tailors today.

Chalk powder was sometimes consumed orally as a remedy for indigestion or heartburn. Additionally, chalk was also used as an ingredient in medicinal compounds and poultices applied externally for skin ailments or soothing irritations.

Colouring

Chalk was ground into a fine powder and used as a white pigment in medieval art and decoration. Artists would mix chalk powder with binders like water, egg whites, or animal glue to create a white paint known as “gesso.” Gesso was used as a base layer for paintings, sculptures, and gilding, providing a smooth and luminous surface.

Another product that featured chalk heavily was medieval cosmetics, particularly in the creation of face powders and foundations.

Finely ground chalk powder was mixed with other substances like white lead or powdered pearls to produce face powders that would give the skin a paler and smoother appearance.
