Hi John- Do you have a pic of this? I'm looking for a red-orange glaze that picks up black spots when used on an iron-bearing clay. Does this do that, or is it a solid, opaque color? Thanks.

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

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

You might try :

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?

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.
