As per subject, what material are the gas burners on the hob made of?

SWMBO has burnt something onto one and wants me to clean it off. I'd
usually start with a soak in Soda Crystals but that's a no-no for
aluminium. It feels light and is non-magnetic.

It's a Russell Hobbs and the only help in the manual is to use a metal
surface cleaner - suggestions?


The usual method is to use XRF to identify the metal/alloy.....

Can't find a decent spectrometer on ebay


you have to look for x-ray fluorescence spectrometer and the three main
suppliers of this equipment are

Fischer scientific
Niton Uk
Oxford Instruments

They are not the sort of thing you will find on Ebay.

Alternatively you could buy a SEM with an EDS or WDS spectrometer
attached but that means destructively cutting your object to give you a
small sample to put into the vacuum chamber.
