AOEYnes 0 Posted November 23, 2020 Report Share Posted November 23, 2020 (edited) Hello, I have been in contact with different companies and labs and asked if they did oxide analysis of clay and how much it would cost. Some did not, some only analysed metal content, not oxides and some labs vere a bit expensive. I am hoping to, in time afford a thorough analyse from SGS Minerals, which would cost apprx 350$. I use marine clay, arctic brick clay which is ice age deposited everywhere here in Norway. This near polar area holds billions and billions of very fine earthenware clay. Much more finely particled than any other clay or porcelain. I am hoping to be able to better mix the clay as glaze base if I can acquire the percentages of its different constituents. I know mix the clay body with 15% puraflo blueclay (50% SiO2). Anyway, I like this clay, I think using lokal clay is the base for any potterycraft and I would like to know a bit more about it, do you know of anyone that can do a simple analyse of this clay for the 4-5 most prevalent oxides?

PeterH 130 Posted November 23, 2020 Report Share Posted November 23, 2020 Any interest? Use of Greenlandic resources for the production of bricks https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwiJ-emZvJntAhVDSxUIHR9OB18QFjAGegQIBxAC&url=http%3A%2F%2Forbit.dtu.dk%2Ffiles%2F126945450%2FThesis_til_orbit.pdf&usg=AOvVaw2oMF4lP_Sg5P0_zuXaTlrz Quote Link to post Share on other sites
Min 3,432 Posted November 23, 2020 Report Share Posted November 23, 2020 @PeterH, I got an unsafe warning when I went to open the link you posted. Is it the same as this? 3 areas of Norway marine clay samples at various depths. https://www.ecsmge-2019.com/uploads/2/1/7/9/21790806/0265-ecsmge-2019_paniagua.pdf Quote Link to post Share on other sites

AOEYnes 0 Posted November 23, 2020 Author Report Share Posted November 23, 2020 It is definetly interesting to see the values, but with sediments, one bay can differ greatly from another so the clay in different places , with only miles apart can have quite dissimilar percentages of the different oxides, so using a table like this has no appliance when it comes to mixing.

Min 3,432 Posted November 24, 2020 Report Share Posted November 24, 2020 @GreyBird had a samples tested at Mineral Labs, I don't know how much they would charge for what you are looking for, she paid $500- for comprehensive testing. Thread with the information she got is here. Hulk 1 Quote Link to post Share on other sites
