    No it doesn't contain lead. Glazes never have, because of the temperature required to fire a glaze. Glazes are basically powdered glass and the glass melts in the kiln and attaches to the ceramic.

    Lead is a very low melting and boiling element and would burn out of any glaze mix without doing anything useful
