Any idea what minerals in the wood cause this?

Typical opal will fluoresce bright green under SW UV light. The link below will give you a list of many possibilities based on colour for both LW and SW UV light.

rocknrob: There was a shop in Portland, don't know if it's still there called Kenny and Zukes who made the absolute best pastrami sandwiches I have ever had. The problem is every restaurant thinks their sandwich is worth $20 now and seldom makes the grade. Nov 12, 2024 9:53:31 GMT -5

rocknrob: So, to end my thread on sandwiches. If you find your sandwich worthy of that price by all means keep going to that restaurant (chewie)
