What type of material is commonly found in the creation of doll heads and body parts in composition dolls?

The material commonly found in the creation of doll heads and body parts in composition dolls is sawdust and glue. Composition dolls became popular in the early 20th century, and their bodies were typically made from a mixture of sawdust, wood pulp, and glue, which was pressed into molds to form the doll's body and head. This process allowed for a durable and lightweight product that could be mass-produced relatively easily.

The composition material was designed to replicate the look and feel of porcelain but at a lower cost and with greater resistance to breakage. The use of sawdust and glue also contributed to the distinct texture and finish of these dolls, which were often painted to resemble more expensive materials.

Other materials mentioned in the choices, while they may be used in doll manufacturing, are not typical for composition dolls specifically. For example, plastic and foam are more associated with modern dolls, while glass and metal are used in collectible dolls rather than composition dolls. Rubber and resin might be found in contemporary manufacturing processes but do not pertain to the traditional composition method.
