What does encaustic mean?
Encaustic describes an ancient painting technique in which pigments are blended with hot, typically beeswax-based medium and applied while warm, then bonded to the surface through further heating. The word functions as both an adjective, as in "an encaustic portrait," and a noun denoting the resulting artwork itself. The method is best known from the remarkably well-preserved Fayum mummy portraits of Roman Egypt, whose wax surfaces have retained their color for centuries. In a separate but related sense, "encaustic tiles" refers to inlaid ceramic floor and wall tiles, popular in medieval churches and revived in the Victorian era, where colored clays are set into a base before firing rather than painted on afterward. Today the term is largely confined to art historical, archaeological, and studio contexts, though encaustic painting has enjoyed renewed popularity among contemporary artists drawn to its tactile, luminous, and durable surfaces. It carries a scholarly, specialized tone rather than everyday currency.
(of paint, pigment, or a work of art) made with colors mixed with hot wax and fixed by heat.
"The gallery acquired an encaustic panel attributed to a Hellenistic workshop."
A painting executed by the encaustic method; also, in ceramics, a tile decorated by inlaying colored clay into an unglazed body before firing.
"Among the collection's treasures is a Roman-era encaustic of a young woman holding a stylus."
In ceramics, "encaustic tile" is the standard term; the noun sense referring to tiles usually appears attributively.
The plural "encaustics" occasionally refers collectively to works made by this method, but the singular is more common even for multiple pieces.
"The exhibition brought together encaustics spanning two millennia."
The encaustic mummy portraits of Roman Egypt still glow with lifelike color after some 2,000 years — because pigment mixed in beeswax simply refuses to fade.

Etymology of encaustic
Encaustic derives from the Greek enkaustikos, meaning "burnt in," from enkaiesthai, "to burn in," formed on the verb kaiein, "to burn." It passed into English via Latin encausticus, appearing in English in the early modern period. The same Greek root gives English "caustic," "cautery," and "cauterize," all sharing the underlying idea of burning — fitting, since encaustic painting literally fixes pigment with heat.
How encaustic is actually used
A technical term used chiefly in art history, conservation, and ceramics contexts. In contemporary usage it most often appears in discussions of painting media, especially the revival of wax painting among modern artists.
Easily confused with encaustic
"Caustic" means capable of burning or corroding, while "encaustic" refers to a painting technique using hot wax — both derive from the same Greek root meaning "to burn," but their meanings differ entirely.
