Theresia Gruber, known as Tresl da Ulëta, bequeathed Museum Gherdëina a collection of terracotta figurines and ceramic works. Daughter of two artists, and an art teacher herself, she dealt with a variety of materials all her life and was a promoter of the Ladin language back in the 1930s. In 1970, when she was 73 years old, she set up a pottery school in Belém in Brazil. 

A stylised depiction of a double eagle in slip decoration, the sign of the cross and the year 1828 adorn a large glazed clay plate. More decorative elements are arranged in concentric circles. Ceramic utensils were typical for Tyrol, and this plate comes from Hof Rescion in Überwasser.

This small, rounded clay vessel was excavated on Picberg along with a handful of calcined bone remnants from animal sacrifices (cow, sheep). This find was probably in connection with a depositing ritual after a sacrificial ceremony carried out on a mountain top. The discovery site and altitude point towards an Iron Age fire sacrifice site.

Fragments of several pitchers made of so-called 'Melaun ceramic' from the late Bronze Age were discovered at Lech Sant at Mastlé (Aschgleralm). These jugs feature girlands and small vertical borders going down the sides. They were principally used for religious rituals at cult sites or cremations as vessels for pouring special liquids.

Fragments of several 'classic' Laugen jugs (named after the discovery site near Brixen) were found on the Burgstall crest at 2400-2500 metres above sea level. They are assumed to be libation vessels that were deliberately smashed during cult acts. The weather-beaten shards of clay from the late Bronze Age are part of a series of discoveries from the Schlern plateau, which is assumed to have been a fire sacrifice site (1200-1000 B.C.).

A large, shallow, pan-like bowl with two side handles was unearthed during excavation of a floor in a Rhaetian dwelling south of Col de Flam historical farm side. The excavation work was carried out druing the extension of the from from St. Ulrich to St. Jakob and provided the first certain proof of an Iron Age settlement at Col de Flam.

In prehistoric dwellings, large ceramic containers were used to keep foodstuffs in. These coarse clay shards have decorative trims going around them, partly smooth, partly with indentations. The finds come from Rabanserhof in St. Peter at Lajen, the original parish of Gröden. They were unearthed during excavation of a house from the mid Bronze Age (1500 - 1350 B.C.).

The fragments of several 'classic' late Bronze Age jugs from the Laugen culture were found northwest of Raschötz upper cable car terminal. The jugs are characterised by two wartlike bumps on the side of the lip and have a thick handle with a ribbon-shaped profile. Research still has to clarify whether the finds are connected with a high place of worship or a burnt-down  mountain shepherd's hut from the Bronze Age.

This terracotta tile features a vivid depiction of some musicians. In terms of its depicted content and original function, this object is difficult to interpret and categorize stylistically. It comes from Stufan farm, yet the exact circumstances of its discovery are unknown. Thermoluminescence dating techniques are therefore uncertain, 13th to beginning 15th century.
