What it is
A lamp with a fuel tank that is pressurised and vaporised on passing through a heated tube, producing a very hot, directed flame. It was used for tin soldering, paint stripping and heating metal parts.
It is credited to Carl Richard Nyberg (1882), but the manufacturer Max Sievert (Sundbyberg) also developed it in the same decade and his brand dominated production; the dates and priority between them are unclear.
What it led to
- soft soldering and heating of parts in workshops, plumbing and building
- petrol, propane and butane torches
- oxyacetylene welding sets
