Recipe #1 (minus the cobalt): https://glazy.org/recipes/151716
Recipe #2, low magnesium, haven't tested yet: https://glazy.org/recipes/472422
I'm new to pottery and making glaze. The 1st recipe covered my dark clay well and made a nice texture so I've ordered mason stains to play with. I've seen a very vague mention of magnesium not playing well with some so I'm looking for insight before starting. The main info I have is on the mason stain reference page here. The two green shades I ordered say they're best without zinc and I saw a correlation with magnesium, so it's possible I might have trouble with green...? A couple of the colors say they'd do better with some zinc in the recipe, the rest I ordered are fine with or without it. Does anyone know how much should be added? I don't see any zinc on the analysis for either recipe.
Since the top recipe makes white rather than clear, is it best to keep it as-is when wanting vibrant colors or should I remove the zircopax? I read somewhere that mixing into white will make more pastel colors, which is actually what I want to start with. A test I saw without zircopax didn't cover darker clay so I don't see the recipe working without it.
Thanks for any thoughts you have on this! It's just a hobby during the little free time I have very little understanding of the chemistry.
