This dataset consists of elemental concentration from floatglass as obtained with LA-ICPMS. The measurements are from reference glass from casework, collected in the past 10 years or so.
The dataset consists of two parts:
- the data used for training the two-level model. It consists of 3 replicated measurements per glass particle.
- the validation data, consisting of five replicates per glass particle, divided in ‘duplos’ and ‘triplos’ for cross-comparison.
Each particle is from a different reference window. The elemental concentrations are on a log_10 basis, and normalized to Si.
