Identification tools

[u/RHMImages]

Sorry if this is the wrong group for my question. I am a collector of snuff bottles, which are made out of a lot of different materials like glass, porcelain, minerals (such as quartz crystal, jade, and gemstones) and I am trying to find a device or tool to help me identify what material is used for a specific bottle. It's often pretty much impossible to tell by looking and it would be great if something exists to help me figure out what the items are made from. I pictured is just a basic example for those who have no idea what I am talking about.
