Property Predictor¶
The Property Predictor is an interface to predict the values of desired properties for specified glass compositions.
It allows the user to select the appropriate method (model) for performing the predictions.
Models¶
Currently, only GlassNet is available.
GlassNet¶
GlassNet , a multitask model deep neural network model developed by Daniel R. Cassar that is capable of predicting 85 different properties.
Please cite the following paper if you're using this model in your research:
Cassar, D.R. (2023). GlassNet: A multitask deep neural network for predicting many glass properties. Ceramics International 49, 36013–36024. 10.1016/j.ceramint.2023.08.281.
Note
Some properties predicted by GlassNet use different units (and scaling) than SciGlass. Check the Property section below for details.
In Sciglass Next, we still use the default units used in SciGlass for consistency as default.
Compositions¶
You can specify up to 15 component names and the corresponding values as input for the prediction.
An autocomplete dropdown list will be shown when you click on the component input fields:
Note that the names in the dropdown list are from the SciGlass database and should cover most common components.
If the name you typed does not match in the database, it may still be used as input as long as it is valid.
Warning
When using the GlassNet model, only the elements between atomic numbers 1 and 83 (hydrogen and bismuth included) were considered, excluding promethium and the noble gases.
If GlassNet cannot handle the names, a warning message will be shown.
Concentration¶
Specify the kind of percent for the value fields. The following options are available:
- Mol% (Molar %)
- Wt% (Weight %)
The default is in Mol%.
Paste¶
Paste the composition copied from other places. This is not available yet.
Clear¶
You can click on the Clear button to clear all component and value fields.
Predict¶
Click on the Predict button to make a prediction with the entered glass compositions and the chosen model.
Property¶
All 85 properties (with scaling and units) available in GlassNet are shown below extracted from the paper in comparison to SciGlass.
GlassNet uses the International System of Units (SI) unit by default. In SciGlass Next, we still use the default units used in SciGlass for consistency.

View (Property Filter)¶
If you are only interested in some properties, you can switch the visibility with this function on the right-hand side.
For example, with only Density group visible:
Unit (Unit Converter)¶
You can use this function to switch to different units for different properties.
Currently we offer the following options for unit conversion:
- Default (SciGlass units)
- International System of Units (SI)
- Custom (User-defined units)
Note
There are currently only few properties and units available for unit conversion.
If you have any suggestions/preferences, please let us know so that we can add more units.
Example¶
With SiO2=70, B2O3=20, Na2O=10 in mol%
Tip
The composition values are rescaled in GlassNet, i.e. the total sum does not have to be 100.
If we type SiO2=0.7, B2O3=0.2, Na2O=0.1, the results will be the same.
You can also switch to grid view for better comparison ans export the data to Excel/CSV format:
Or you can switch to the plot view for visualization:
Currently, only the temperature-dependent properties are available for plotting.
