Karas that we encountered weren't large in volume, probably between 100 to 200 L, they had a very clear appearance (white clay?) and some had reddish color pattern like Hidasuki (Fire markings) of Bizen from Japan.

"Anfora" making, is it artisanal or industrial? This is our question because we have a strong feeling for the specific method of hand forming, although in Italy they often use the mold. In addition, the Italians not only use clay, otherwise, "grès (sandstone)" or reformed clay as well. The advantage: The use of mold allows the manufacturer to produce containers with exactly the same volume as industrial products.

Are there good quality clays for pottery in France? A serious question. Was it not because there was no satisfactory quality that the French began to vinify in wood? What we hear is that French amphorae drink a lot (like a hole = heavy “BOOZER”), in other words, they leak a lot, no good porosity. Some potter imports clay from Italy ...

Spanish "Tinajas" are, unlike the Italian anforas, very handcrafted especially in Villarrobledo and Catalonia. Potters still work in the traditional way, that is to say, hand forming. However, unfortunately, they are no longer able to make large format tinajas, up to 6-7000 L, which all the villagers have participated in making together.

Most tinajas are neutral without inner treatment.

In Japan, most of potters are "Artists" instead of "Craftsmen". (We dislike the term "ceramist" that we find pretentious). Their creations are considered to be fine arts. It says that they are very expensive even though they are in the form of everyday items. Advantage : Very beautiful, certainly, they have one of the best qualities of pottery in the world.
