Their clay was not red, it was brown and the iron within it turned it red, finding red clay in New England would be like finding gold in the toilet after you turn ok a shite.
It depends on where you get your clay from. Brown comes from maganese and no matter how much iron you add, it´ll always fire dark brown because of the manganese. Iron inpurities turn red when less or no manganese is present.
I live on an island in Hawaii which has a lot of red dirt, clay. I recently dug some up and made clay out of it. Did a test piece to fire. It did fire and didn't break when struck against something. Although later it ws brittle and did crumble. My other test piece which I got from a darker gray red area seemed to be moreplastic and held up better in the firing process and is still all together. I was wondering what I could do to make the red clay here more plastic . Hold together better in firing? I am brand new to making pottery and am fascinated by the pueblo pottery and want to make stuff like that with Hawaiian petroglyph designs painted on it . Could you give me some hints on this.?

Very old comment, but one way to make clay more plastic is to add something basic to neutralize the clay. Traditionally this might be wood ash but many additives can work, even crushed sea shells (calcium carbonate)
Is Georgia Red Clay and Red Clay Pottery the same material? I heard Red Clay cannot be used for cooking, storaging food or hold water as it is not cured. Is this information correct?
Red clay is just white clay with iron oxide in it. It´s the most common type of clay and can be found in many places all over the globe. You can use it for cooking. Cookware made of red clay was common in Europe till iron or copper pots were available. The trick is to fire it at a low temperature. I still make pie dishes out of red clay.
The firing temperature depends on the clay. I can get local red clay and have to fire at 1150°C. Last year I was in Sicily and talked to a few potters in Caltagirone. They fire their Terra Cotta around 1030°C. It depends on what you´re working with.

Hi Ned, I used to do shows and met you at Annandale, Va. Glad to see you are still potting, we moved to Canada and pot up here. Take care. Vaughan
I like it! and cats too)))
A great pottery video with bonus cats.
LoL, That looks just like the cat Lester had living in his work shop, I guess a great potter needs a free spirited cat in the work shop.

@@mcRydes To make it more plastic, you can add some bentonite. That stuff make a huge difference.

Jesus Llenza if you glaze it with a gloss you can but it is so porous and correct uncured and unsafe for edibles before glaze

At what temperature do u fire red clay, in my country it goes upto 1050 max.
