I'm going to buy some mason stain test packs, and I'm wondering what color blue people like to use.

I will be using it to make colored porcelain. I've used Wedgewood 6310 with good results, but it comes out on the slightly purple side.

Thanks

hi matt,

I use Zircon Blue (Mason 6315) that I get from Pottery Supply house in Canada.

Depending on how much you use, you can get a nice medium blue from it.

I cant find a picture of it where we used it though or else I would share.

Hope this helps

I use Mazarene Blue ... It goes from deep blue to a lovely faded denim color as you add white clay.

I've used colbalt oxide , it's a very vibrant blue. A little goes a very long way.

I've used MS Robin's Egg with a low fire porcelain clay body. It fired to Cone 6 and maintained a light blue that was true to the color of the original stain material.I was awhile ago, but I believe I used 7%.

Just a note that a few years ago I noticed that the Robins Egg changed. So please test any of these suggestions before making an investment.

Thanks for all the suggestions.

I know cobalt is the most common for blue, which is used in mazerine, but I see lighter stains use vanadium with zirconium.

I'll order some samples of mazerine and the others, then do some tests. It looks like Mason Color Works used to blend a cobalt containing stain with a vanadium, to get bright blue. I'll have to try that too.

Thanks again.
