Heated waving irons
Compare tong shape, handle insulation, heat source and the hair arrangement. Marcel waving used heated irons to create temporary waves; it was not itself a permanent-wave chemical process.
Three everyday objects, many centuries of craft, industry and social history.
← All research collectionsA mirror, a comb and a brush are so familiar that their history is easily overlooked. Yet each object brings together raw materials, specialist workshops, changing fashions, trade routes and the everyday routines of hairdressers and their clients.
From everyday workshop objects to specialised electrical equipment: follow the material, manufacturing technique, working practice and surviving historical evidence.
Mirrors shaped the arrangement of salons and the relationship between practitioner and client. Their history involves glassmaking, reflective coatings, furniture, lighting and the changing experience of seeing oneself.
Combs and brushes served different functions: separating, arranging, detangling, cleaning and finishing hair. Their forms depend on materials, methods of manufacture and the work for which they were designed.
Object-based research · Technical history
A surviving object tells us something different from an advertisement or a patent. The object can reveal materials, dimensions, wear and construction; a patent records a disclosed technical proposal; trade literature may establish marketing claims and intended users. None alone proves widespread adoption.
Compare tong shape, handle insulation, heat source and the hair arrangement. Marcel waving used heated irons to create temporary waves; it was not itself a permanent-wave chemical process.
Study tooth or bristle arrangement, handle materials, manufacturing marks and repair traces. Patent evidence can document innovations, but individual dates of invention require verification.
Investigate glass production, reflective coatings, furniture, illumination and the social arrangement of the salon. Separate the history of manufacture from the history of salon use.
Heating elements, rods, suspension arms and scalp protection must be understood as parts of a working system rather than as interchangeable inventions.
Object / manufacturer · approximate date · place · material · measurements · inscriptions · mechanism · provenance · image rights · primary source · confidence level. Record uncertain identifications as such rather than converting them into definite attributions.
Research leads: Lyda D. Newman’s US 614,335 (1898) is a useful patent starting point for brush history; contemporary catalogues and surviving examples are needed to assess manufacture and use. Read the patent →
Mirrors, combs and brushes were everyday working tools; permanent-waving machines belonged to a different category of specialised equipment. Studying their use together can nevertheless illuminate the organisation of a salon and the changing relationship between manual skill and mechanical apparatus.
Marjorie Stewart Joyner’s 1928 design is an example: its overhead dome supported several electrically heated curling irons, while separate clamps reduced the weight borne by the client’s hair. The patent also illustrated scalp protection during winding.

Marcel waving illustrates why an implement must be studied alongside the hand technique used with it. Heated tongs did not produce the wave automatically: temperature, pressure, direction and timing were all matters of professional skill.
The surviving package offers evidence of product presentation and printed directions. Its language, manufacturer’s marks and construction should be transcribed and compared with dated advertisements before assigning a production date. It is not itself a patent for the original invention.
For the distinction between temporary thermal waving and permanent chemical waving, see Technology & Patents: Marcel Grateau. The patented electric heater for flat winding is examined separately under Josef Mayer.
The Technology & Patents collection now contains a detailed, evidence-labelled catalogue of Nessler, Gallia, Szeemann, Suter, Calvete, Croquignole, Frederics, Mayer and Joyner, alongside the distinct Marcel method. Explore the comparative catalogue →
