I needed to buy a memorial tree in Roselawn. When I took the people I'd bought it for to see it we found it was stunted and misshapen.
I'm surprised they don't have people with pliers removing any gold teeth or valuable rings before the flames can get at them.
All the metal would, otherwise, have gone to waste. As long as they aren't doing dental extractions prior to cremation there is no harm in seeking the metal.
When I went to pick up my dad's ashes I was amazed at how heavy they were, maybe just something that I had never thought about before. He is living in Loch Earn these days - bit chilly just now.
