Don't have a picture right now..maybe later?

But it doesn't do that. It is pretty opaque.

Carolanne Currier said...: Thanks, John. That might be worth testing. That recipe spawned another question though - I did not know there was such a thing as Mag Carb light. I've just always seen and bought Mag Carb. What's the diff?; February 9, 2011 at 12:47 PM
John Britt said...: Carolanne,

I think heavy mag. carb. has 4 water while light has 3. For our purposes I think?? that they are essentially the same. I think I get mag. carb. from Highwater and it is the light.; February 9, 2011 at 1:25 PM
