They cast the stones in concrete in a metal salad bowl and insert a metal handle before the concrete hardens. I'm thinking of trying it.
1. What type of concrete should I use?
2. They spray the salad bowl with "cooking spray" before pouring in the cement so that it will come off more easily. What is that? Is there a simple alternative?
Rapeseed/olive oil works to release concrete.
Had to google prices on curling stones... :eek: will start making those in the future...
Best regards, fremax
What it costs to manufacture probably depends on what you're going to use it for; for curling, you have a challenge if you've tried the sport
So these cast ones become a fun toy on some uneven lake ice.
