What Artists Paint On

Canvas, panel, linen, paper, metal and wall: how painting supports are built, prepared, and why the wrong substrate fails decades later

A painting support is the surface paint adheres to: stretched linen, oak panel, watercolour paper, copper sheet, or lime plaster on a wall. This guide maps the main support types, how sizing and gesso prepare them, linen versus cotton weave, stretcher bars and panel cradling, named works in major museums, typical failure modes, and what each option costs in a studio today without turning into a gear catalogue.

What Is Mixed Media?

When paint, paste, print and found objects share one surface: how mixed media works as technique and label, from Cubist paste to Neo-Dada combines and contemporary assemblage

Mixed media art combines two or more materials or techniques in a single work so the label lists more than one substance or process. This guide defines the term against collage and assemblage, traces adhesive chemistry and layering order, reads six museum objects from Picasso to Rauschenberg, and notes how composite works fail in storage.

Diptych and Triptych, Explained

Hinged panels, wings, and the move from Roman writing tablets to Bosch, van Eyck, and Rothko: how two- and three-part formats work as structure, not only as altarpiece lore.

A triptych is a work in three panels, often hinged so outer wings fold over a centre; a diptych uses two. This guide defines both formats and polyptych briefly, traces panel joinery and hardware, walks a workshop sequence, reads six museum examples including Bosch and Rothko, and notes how splits, warping, and bad hinges fail in storage.
