Question: Is this pot flat on the bottom, I have a glass top range. Also, does anyone know which rack to purchase for water bath canning?  Thank you
Document: I love this pot - it is nice and big and works great for all my canning & preserving projects. It fits well on one side of the stove when my enormous hot water bath canner is on the other side, heating up. I can make so much marinara, plum jelly and other goodies with this pot - it's really a great help.The bottom is nice and heavy - the surface cleans well (even if I scorch inside the pot) and the lid fits well.
I bought this 20 qt. pot specifically to boil lobsters. I have an old Granite Ware pot that is plenty big but the bottom doesn't heat well on my electric stove. I fixed two 1-1/2 pound lobsters last night and the pot did it's job admirably. The pot looks great and I like the glass top that allows you to check the water status easily. The riveted handles are rock solid.
Sturdy enough handles. I wondered if glass top might pool water in the handle part when washing, but not so far and there is a screw that could likely fix it. Manufacturers sticker on bottom of pan comes off easily with a micro-sponge.I washed before first use, but I wish I would have boiled water or something else first instead of the red sauce I made. There was a slight synthetic aroma that may have cooked off into the food, that I would have rather boiled and thrown out.
This really is a great pot. I am not sure why anyone would buy a cheap aluminum version when they have this. I use this one for home brewing beer and wine, but really you could make pasta in it if you felt like it. My only complaint is that the top is glass and it could possibly break, but so far I have no corrosion to report. Very happy.
Just received this pot. It is a nice pot, with a nice thick bottom. I filled it up with water to a level I would be comfortable boiling liquid at, about 1.5" from the top, and to my surprise it only holds just under 3.5 gallons. I would understand if it was 20 quarts to the rim of the pot, but it is barely 16! It is a nice pot for the price, but definitely not as big as advertised.
A little defect in the base (piece of loose metal rattling around in there), but most importantly it is flat and heavy on the bottom. I would actually prefer stainless lid, but glass is fine, especially considering the price overall.
I purchased this pot for extract brewing based on all of the positive comments, and it has lived up to all of them. A big heavy bottom coupled with a nice glass lid made paying a little extra for this pot well worth it. One of the best things is the fluted lip that made pouring directly from the pot a breeze. I am looking forward to using it for non-brewing cooking and would highly recommend this to anyone.
This pot is first-class: heavy bottom, strong and easy to hold handles, well-fitting lid, nice shape. It is beautiful as well as functional. I have seen similar in stores for almost twice the price. It sits nice and flat on my electric range, heats well and holds the heat for a long time, perfect for long cooking of soups and stews. It cleans up well, with nothing burning or sticking. I don't think one can do better.
I use this pot when I want to make large batches of fish stew. It is very thick on the bottom to help ensure even cooking and less burning and the handles seem like they will hold up well. I was nervous about the glass top cracking at first but it is pretty thick and doesnt seem to be a problem.
The glass lid is nice and weighty, the kind of weight that lets you know it's stout. The bottom is thick, distributes heat evenly without scorching. I have no doubt this will give me years of excellent service if I treat it well and take care of it. You wouldn't bang this around in a commercial kitchen, the sides are thin and wouldn't take industrial abuse. But they certainly will put up with any average home kitchen.
Answer: It is flat on the bottom.  It has a diameter of 11 3/4 inches and a depth of 9 1/2 inches.  You would need to having a canning rack that would fit down into the pan so the jars are covered in boiling water.
