Hello

I found a video online on how to cast a curling stone:
http://youtu.be/vdFCZHeOxeE

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.

A person holding a homemade concrete curling stone with a metal handle, placed on a textured floor.
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 the concrete.
Had to google prices on curling stones... :eek: will start making those soon...

Kind 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.
