why this product

Use this cup to quickly separate meat and poultry juices from fat when making your gravy. Fat, being lighter in weight than water, naturally rises to the top. The low-placed spout easily pours off the juices while confining the fat within the container.

The glass cup is machine blown in order to achieve exact measurements and sizes while the spouts are manually attached. They are made with borosilicate glass, a strong material used in laboratories and kitchens due to its resistance to thermal expansion and shock. Borosilicate glass is 17% lighter than aluminum – making your work easier when slowly pouring your the turkey drippings into your cooking roux.

The glass is heat resistant up to 450 °C (842 °F), so you can pour hot juices directly into the vessel without fear of it cracking.

use & care

Pour meat drippings in the glass fat separator. Within a few minutes, the fat rises to the top, and the low spout allows you to pour out only the juices from the bottom. 

The fat separator is safe for use in the microwave, dishwasher and stove (only for heating clear liquids) and can also be put in the freezer down to temperatures of -35 °C (-31 °F).

Although the borosilicate glass is thermal resistant, sudden changes in temperature may still cause volatile expansion and shrinking that leads to cracking. Leave hot glassware to cool before storing in the refrigerator or freezer.

The pore-free surface cleans easily in the dishwasher, or by hand.


production & design

German inventor Otto Schott developed the first borosilicate glass in 1893 by adding boric oxide to the traditional glassmaker's cocktail of silicate sand, soda and ground lime. The new material was immediately marketed for laboratory and industrial use as well as for the home kitchen.

The decade-old German company that created this fat separator continues to innovate upon that initial innovation for the domestic market, winning the iF product design award for 2013, a juried exhibition and awards ceremony mounted in 1953 by International Forum Design of Hannover, Germany.
