Jacobs also paints on rigid wood panels, their surfaces absorbent enough for molten wax to adhere. See Encaustic Works on Wood/Paintings. Jacobs paints layer upon layer of pigmented wax, fusing each layer with a heat gun or propane blowtorch. It is the heat and the fusing process that bond the layers of paint together permanently. She typically scrapes, gouges, and makes marks on the wax in order to achieve certain effects, then again fuses with heat. She sometimes collages paper, fabric, metallic pieces, and other elements into the painting. Some of the paintings on wood are framed; others are not. Prints are available.
In addition to painting encaustic on wood, Jacobs attaches photographs to smooth wood panels, then paints the photographs with clear encaustic medium until she achieves a smooth, even surface intended to imbue the photographs with qualities of permanence, mystery, and fragility. The pieces shown in Encaustic Works on Wood/Photographs are representative of this series. All are framed.
