摘要： A method of producing amorphous sample bodies that can be used for optical spectral analysis and X-ray spectral analysis, by batch-wise smelting in a crucible a mixture of analysis sample and a flux. The method is characterized by allowing a controlled flow of molten material to run out of the crucible and successively down onto a horizontal receiving surface and there form the sample bodies. The mixture is smelted suitably at a temperature of between 800.degree. and 1300.degree. C., preferably at about 1000.degree. C., and is carried out in a crucible having a hole in the bottom thereof. A apparatus for producing such amorphous sample bodies is also disclosed. The apparatus includes a smelt crucible provided with an opening in its lower part and which is designed to be downwardly tapered at least inside in order to prevent the mixture from coming out, but to facilitate running of molten material through the opening. The apparatus will also preferably include a casting plate or a mould for casting sample bodies positioned horizontally beneath the crucible. The method and apparatus can be used in the production of sample bodies for the analysis of geological material, inorganic environment test material and sulfidic and/or oxidic products from ferrous and non-ferrous production processes.
