Natural flour glue is used in mosaics or restoration because it is free from any ingredients that could harm or stain the support (canvas or paper).
 The indirect method requires the use of a binder that can be easily removed from the paper or mesh backing.
 Boiled flour paste is made from a mixture of boiled water, salt, and flour and is the best solution for this purpose.
 This glue is also highly recommended for creating papier-mâché works.
