Concerns around black clay safety are understandable, as some historical black clay bodies used manganese oxide pigmentation.
Nigra 2002 is manufactured by a reputable European supplier and pigmented using safe manufactured stains rather than manganese oxide. The supplier confirms the clay body is suitable for studio and ceramic use.

Great colour rich red used on my chickens. Used 2 coats of deep glossy red on the chicken body and 1 coat of lucent indigo.

I don’t have a proper picture but all 10 pieces turned out bubbled. Tiny little bubbles.l through the glaze. The clay is a Keanes stoneware and 3 good layers didn’t bring out the yellow but I’ve got another batch going in so maybe this will come out differently.

Such beautiful smooth clay and dries white , Haven’t fired it yet- looking forward to it

About this piece , I printed a clay from a wood block , so the glaze really fits to it

Stunning glaze, dips beautifully, this is layered under a pink with flux and it’s a wonderful combo!
Kara A. 5/5 Verified
Stunning!! Absolutely love the way it breaks and the slight crystalline affect where it pools 😍
Kara A. 5/5 Verified
Gorgeous! Two of your new glazes. Amazon and Camelia. Brushed on beautifully. The Amazon ruins a bit but I love the effect.

Lovely to work with and stable holds its shape in the kiln on glaze

My new favorite clay
Daniel M. 5/5 Verified
Gorgeous glaze, deep green and translucent as expected. Just a little tricky to apply (like a dipping glaze) so I might need to add some brushing medium.

These aren’t the best pictures but it’s wonderful, sparkles gold in the light, with just the right amount of iron.

I have only put it on a test tile, as yet, but it came out perfectly, gorgeous glaze

I love the colours and as someone new to pottery it’s just exciting to know that this product has quality and a huge range of colour. Looking forward to adding more to my existing colours and exploring what magic can happen with them!

Love it, a very nice purple glaze. Shows texture. Very happy
Kathryn G. 5/5 Verified
Beautiful deep dark green. I probably should have applied a little thicker, but very happy. Some lovely crystals too. Looking forward to exploring more

First time user , it does run a bit but the speckled effect is lovely.
Lyn B. 5/5 Verified
Really smooth and satisfying to throw with, holds its shape well
Iseult S. 5/5 Verified
Excellent clay great for everything sculpting or wheel
Linda F. 5/5 Verified
The colour has very little nuance. It may look better over/under other glazes
Iseult S. 2/5 Verified
Love the matt texture and varied surface finish I was able to achieve with this turquoise glaze.
Lisa H. 5/5 Verified
Purchased the clay a few months ago, finally have time to try it, nice texture and strength, very easy to throw, definitely will order again once I finish my current stock.
Betty Ma M. 5/5 Verified
The darker ones were a refire over another glaze. The lighter one is the true colour but I really like it and very true to expected result.
Lyn F. 5/5 Verified
Versatile medium hand build slab work and wheel throwing. I think this is my new favourite . I absolutely love this stone ware nigra clay, couldn't be happier with my results
