Pyrex glass works all started when a request came in from the railroads to create a lantern glass that would not break when the hot glass was hit by rain or snow. A glass was developed that could handle these conditions and was so successful that the company saw a sales decline in replacement globes. This "fire glass", was resistant to temperature changes, corrosion and even breakage.
This very glass eventually was found to be an excellent baking solution. Since it would not easily chip or crack, and produced a very even cooking environment. by 1915 Pyrex had a line of glass bake ware that hit the marketplace.
Nowadays you see Pyrex bake ware in all different forms shapes and sizes...and even in Coffee Percolators!

I’m wondering if I can replacement parts for the Pyrex glass percolator. I’m in the Edmonton, Alberta, Canada area.
there are plenty of parts available. Just check all the swap meets and garage sales.
It is easy to find complete units with all the parts in all sizes for very little money. I have several sizes.. I love my 4 cup pyrex percolator and use it every weekend.. I put a paper filter in the brew basket and it works beautifully.. Nothing makes better coffer unless it’s cowboy brew… Thats the best… good luck you will find it… Not rare…
I have a pyrex glass percolator wonder if it can be used on an electric stove or a gas stove. I surely do not want to break it. I have an electric warmer with it but it does not heat enough to perc coffee. I love percolated coffee so am anxious to use it.
Yes..it can be used on electric/gas stoves. I used to make coffee for my parents in theirs. I have one, but need a replacement stem. I use it all the time to brew tea and coffee
I don’t think a Pyrex glass should be used directly on an electric stove. I was just researching this subject…
I just bought one of the 6 cup unit clear glass perculators and used it on my gas stove, but I was afraid that it would break so I used an alum. pan on the heat and put the pot on top of it…The coffee came out wonderful…its so cool….I am thrilled. There is a site for Pyrex with directions, but I would not put it on direct heat unless someone can guarantee it won’t break. I guess you can buy some type of gadget to put on your stove top, but I needed to use it today…
I grew up with these coffee pots. Ours came with a little wire thing that you’re supposed to use between an electric plate and the coffee pot. The instructions say that if you put it straight on the hot-plate the glass can sometimes crack.
But if you’re using it on a gas stove you can put it straight on the flame. Remember this is the same kind of glass you used in Chemistry lab in school.
HTH.
I have had a pyrex coffeepot in my family since I was little it has always gone directly on the gas stove and works great
5minuts after you lower the hear once it starts to perk makes the best coffee
Does anybody know if they still make these? I can only find them used. I’d rather start new. Would love to bring back those childhood memories!
Unfortunately they don’t make these percolators anymore (not since the early 70′s), but the glass and the aluminum components are super easy to clean. Mine looks like new and it is a model from the early 50′s.
