Frau Kroger Mirror Glass Container
Made by Raumgestalt
Christian Metzner drew from the quiet ceremony of British teatime, specifically the modest milk and sugar jug, to shape the Frau Kroger Container. The result is something that sits between archetype and experiment: a conical form in mouth-blown borosilicate glass that carries the precision of laboratory ware alongside the familiarity of the table.
Three spouts are set at equal intervals around the rim, a considered departure from convention. The user never needs to rotate the vessel to find the pour. It is a small gesture with a significant effect on how the object is handled.
- Mouth-blown borosilicate glass, heatproof and durable
- Reflective silver glazing applied to the interior surface
- Three evenly spaced spouts integrated into the conical form
- Designed by Christian Metzner for Raumgestalt
The mirrored interior gives the container a strong presence at the table, catching light in a way that plain glass does not. It is equally suited to milk, cream, syrups, or dressings, the form making no assumptions about its contents.

Frequently Asked Questions
What is borosilicate glass and is it safe for hot liquids?
Borosilicate glass contains boron trioxide, which gives it a very low coefficient of thermal expansion. This makes it highly resistant to thermal shock, so it can safely hold hot liquids without cracking or warping.
What is the purpose of the three spouts on the Frau Kroger Container?
The three spouts are positioned at equal intervals around the rim so that the vessel can be poured from any angle without turning it. This is a functional reinterpretation of the standard single-spout jug form.
How is the mirrored interior finish achieved?
The reflective silver effect is a glazing applied to the interior surface of the glass. It creates a mirror-like quality that gives the container visual depth and a distinct presence on the tabletop.
Who is Christian Metzner and what is Raumgestalt?
Christian Metzner is a German product designer known for objects that reframe everyday archetypes through material and formal precision. Raumgestalt is the Berlin-based design studio and brand through which his work is produced and distributed.
Can the Frau Kroger Container be used for substances other than milk or cream?
Yes. The form is intentionally open-ended and suited to any pourable substance, including syrups, dressings, or oils. The borosilicate glass is non-reactive, making it appropriate for a wide range of uses.
