Question: Is this coffee pot for electric only or can you use it on open flame as well?
Document: Following the directions, I  set my gas flame to medium and it turned out great in a short time. The coffee was smooth, clean, and tasted GREAT. The plastic basket and top is not a problem either, it's not flimsy and thin. I'll never go back to an electric pot again and HIGHLY RECOMMEND this one.Suggest: 1- Using the filter assured the grounds did not fall into the pot from the basket.
The smell of coffee brewing is wonderful! I no longer will use an electric coffee pot! The taste is more real to me than electric.
Love it Love it Love it. Havent had one of these in years. Perfect for a back up when the lights are out and cant use the electric coffee pot. Perfect for fixing hot tea.
I used to use the perex percolators all the time. You can't replace the parts anymore. We have power failures in our area all the time and I need my coffee. I love it. Have almost stopped using my electric drip pot.
I love using a glass stovetop percolator. I've been brewing my coffee in one of these for over 20 years, and will never go back to using an electric coffee maker.....unless they stop making these. The coffee tastes so much richer, and you use much less ground coffee, because the coffee actually brews. It doesn't just pass through the grinds one time like in a coffee maker. Yes, it does take longer to make a pot of coffee, but it is worth it.
Great pot for boiling water over direct heat (gas stovetop). Haven't tried it for making coffee, since I just use my small electric Krups 4 cup (actually 2 x 8 oz. )for coffee. Wanted this to boil water for tea, cocoa, instant coffee, soup, etc. Works great on my gas stovetop for large (8 cup +) volume of boiling hot water, or lesser volume if you please.
I have used a percolator in the past growing up,so I am familiar with there operation. This unit seems to be made well until you use it. After the first pot of coffee made I found the Top of the pot becomes dislodged causing spillage while trying to pour the coffee out. Found upon the second try  that the top dislodging causes the top of the brew basket to become dislodged also,causing the coffee grounds to come spilling out along with the coffee as you pour.
Well, I like good coffee (remember, spring water from my spring and hand ground beans? ), I like that I can make coffee without electricity. I like perked coffee (perked as long as I want it perked, not some electric sensor setting length of time), and I like the simplicity (got a weakness for the classics, I guess).Am considering getting another. Time will tell.
I had an old Pyrex all glass percolator for years. Once the glass basket broke I could not find replacements. This percolator makes excellent coffee!! I always use a paper filter found in any grocery store (as I did with my other one)  so you can use any ground coffee. Just make sure you get the "wrap around style" filter and it says made for percolators. I also have gas stove and use a medium low flame for the smoothest tasting coffee.
A very nice glass percolator for use on a propane gas stove. Also can be used on electric stove with the enclosed heat defuser. Makes real good coffee.
