He calls himself a natural clay ceramist: "My products are born from earth and fire to delight people." With great passion, he prepares the clays, shapes them, and experiments with different kilns. His works are a continuous metamorphosis towards the perfection of the interplay between material, form, and their language.

"I already played with clay on my way to school and modeled it with great joy," says Josef Wieser. It was very soon clear that he would dedicate himself to the craft. He learned two apprenticeships that were originally inseparable: stove fitter and ceramist.

His closeness to nature is reflected in his works. "I often roam landscapes in search of geological peculiarities. The region between the limestone Alps and the granite massif, as well as the weathering effects of millions of years, have left different sedimentation formations." Wieser traces abandoned clay and sand pits, old brickworks, or closed glassworks to excavate different clays. "I only process clays and loams that I have dug myself into masses with unmistakable character and lively appearance. I grind rocks and sands for my self-made glazes."

He also uses different kilns for his ceramics: electric kiln, gas kiln for reduction firings, and wood kiln. He started his first attempts with the latter at the age of twelve. "A small shaft kiln served for experiments, later followed by other kilns with different flame paths. Thus, fire has been marking my vessels for over 35 years."

With special passion, Josef Wieser dedicates himself to the East Asian technique of Anagama firing. In this process, the ceramics are exposed to glowing embers and fly ash and thus, at a temperature of 1,300 degrees Celsius, acquire a unique coloration. As an archaic craftsman, researcher, and seeker, he constantly evolves, tries new things, and transforms the unexpected.
