About These Laumontite Specimens

Laumontite is a relatively common zeolite group mineral (that can occur in excellent specimens!) but because it usually dehydrates relatively quickly in air (and can then turn to powder), it is not so commonly preserved and encountered in mineral collections.

These laumontite specimens have been stabilized. After experimentation with various methods and materials, it has been found that a technique using a mixture including water-soluble glue is the most effective, with no impact on the visual appearance of the specimens (colour or lustre). Nova Scotia laumontite specimens stabilized using this method have proven stable over longer than 20 years, with no indication that such stability will change (in mineral cabinets, at approximate normal indoor humidity levels – ranging from approx. 25-75%). Specimens in my own collection are as good as the day they were stabilized.
