A Corningware stovetop percolator is similar to many other stovetop models, only it is made with Corningware ceramic-glass. The set up includes the coffee pot, a lid, a perk stem and a coffee basket. The most popular design for the percolator is the cornflower blue pattern, but several other designs are available.
Fill the coffee pot with water to the fill line marked inside the pot.
Assemble the basket to the stem by sliding the center hole of the basket over the top of the perk stem. Place this assembly into the coffee pot.
Measure the desired amount of coffee into the basket. A good general rule is 1 tbsp. of coffee per cup.
Secure the lid on the percolator.
Place the percolator on one of the smaller eyes of your stove if it is electric. Any stove eye will work on a gas stove.
Turn the heat on the stove to medium high.
Watch for the coffee to perk. You will be able to see the perk bubble though the glass handle top of the lid.
Let the coffee percolate for 6 to 10 minutes.
Serve the coffee. Return the percolator to the stove eye and turn the heat to low to keep the remaining coffee hot, but not boiling.
In general, the longer the coffee perks, the stronger the coffee taste will be. You can overcook coffee to the point of it becoming bitter and undrinkable. You can usually find Corningware stovetop percolators at thrift shops and yard sales for a fraction of the price of new stovetop models. Replacement parts are available for the Corningware stovetop percolator at many online retail shops and outlets.
