There seem to be a number of things that could give rise to headaches there.

The reason I asked was that people are describing anything that it is not a UV
tube as a plate burner or a street light which is thus something beyond the ken
of ordinary people and to be avoided.. The effect is that alt process people are
limiting their abilities.

Any good supplier will be able to tell you what UV sources are used for what
purposes.

That is just a cyanotype. They are very easy and very cheap to make.
There is a lot in the archive but if Laura e mails me I will give her hints.

Taken overall the plate burner Laura mentions is a standard graphic arts lamp
that is nothing to be frightened of. You will find them in art schools in
fashion and ceramics and printing departments across the world where the other
disciplines are using photography in ways undreamt of by photographers. I have
found that introducing these people to each other produces healthy cross
fertilisation of ideas.
