Galium verum L. for

To prepare a painted fabric for comparative purposes, small bands of ferrous oxide, an alizarin/purpurin mixture, ground up bloodroot (Sanguinaria canadensis L.) and bedstraw (Galium verum L.) were painted on linen fabric (Testfabrics L-57). As carriers or binder for the pigment colorants to be painted on the fibrous materials, beef fat was used as a substitute for bear grease and egg white was used as source for albumin. The various combinations of these materials were mixed and painted on areas of the test fabric as outlined in Table III. The painted test fabric was left to diy for 24 hours.
