A barium-zinc frit that contains 11% lead oxide; the maker lists it among its lead frits. Keramik-Kraft sells it simply as 'Zinkbarium Fritte'. It is used for matte and crystalline glaze effects. Expansion is 119 x 10^-7/K, with softening above 870 °C.

Oxide analysis and unity formula

Glazecalc has the analysis of Mondré & Manz Zinc-Barium Lead Frit M 4067 as weight percent of the raw material. The unity contribution is the moles of each oxide in the amount of Mondré & Manz Zinc-Barium Lead Frit M 4067 that holds 1.0 mole of flux, which is how Glazecalc adds it into a recipe's unity formula.

Hazards and safety

This material contains lead oxide (PbO).

Hazards: CONTAINS LEAD (PbO about 11%) and barium (BaO about 38%). Keramik-Kraft lists H351 (suspected of causing cancer), H360FD (may damage fertility or the unborn child), H362 (may harm breast-fed children), H372 (damages organs through prolonged exposure) and H410 (very toxic to aquatic life). It is not suitable for schools or hobby use without proper controls. Lab-test any glaze made with it for lead and barium release before it is used on food or drink surfaces.

Glazecalc shows the hazard wording as its record gives it. It is not a full risk assessment, so read the safety data sheet from your supplier. Before you handle any glaze material, read Safe mixing and ventilation and Glaze safety at home.
