The plates arrived on time, well protected, with a bit too much packaging. They are durable.

These hardness plates are of the highest quality. They are thick enough that student's don't crack them applying pressure. I recommend these for any geology laboratory!

Best quality available today! - We have ordered less expensive glass slides from other companies, but always end up ordering these hardness plates from Wards. They are the best quality, and therefore end up being more economical.
