Method and apparatus for producing a specimen bead in a mouldible (9) for future analysis wherein a halogen gas is passed over the surface of the specimen whilst molten to increase surface tension thereof thus enabling the bead to be released from the mouldible. A furnace (1) has a cradle (8) to support the mouldibles (9) and an injector (12) delivers halogen gas through nozzle 17. Alternatively, a halogen source may be located in the cap or lid of the mouldible. |
