Is it possible to use a Pyrex double boiler on a glass ceramic cooktop
without using the wire spider underneath it (a requirement when using
it on a coil-type element)?

TIA

I'd look up the owner's manual, on line if you don't have it. I just
got rid of my electric, that came with the house, and instr. said not to
use glass. Owned an old JennAir a while back, and made the mistake of
putting an empty pyrex pie plate on a burner I thought was off
(finishing prep for T'giving dinner). About two or three minutes later,
as we had just sat down for dinner in the dining room, the pie plate
exploded! Long shards of glass all over the kitchen, and it sounded
like a bomb. I've never used the Pyrex intended for stove-top cooking,
but letting one boil dry gives me pretty awful hazards to contemplate.
Of course, we never PLAN to let one boil dry. I'm back to gas range and
loving it :o)

Yeah
I just went from electric to gas
Lot cheaper to cook on natural gas

I just got rid of gas cooktop that came with the house and installed electric :) Had to pay $400 for the 240V line and capping off the gas pipe. The lady of the house can't stand the soot and grime cooking on gas creates. This kitchen is open to the rest of the first floor space and no vents anywhere. Can't believe they put a gas cooktop/oven there in the first place.

Back on topic tho: I never knew Pyrex isn't compatible with glass tops. Perhaps it was not the type of the surface per se but just any type of intense heat? It would seem you'd need to be even more careful with gas flames then, no?

I don't know your relative energy rates or how much you cook.
But in my experience, the electricity used by a range, oven isn't
enough to make much difference on an electric bill. In the
typical house, you just don't use it that many hours to make it
matter. Something like AC, now that is a different story. The
choice of gas vs electric is usually a function of preference and
availability.

My exploding pie plate was not intended for stovetop cooking (microwave
or oven). The "pots and pans" made of Pyrex are different, and I have
never used them.

Don't want to start a war over gas vs electric, just that I prefer gas
and have done a lot more cooking with it than elec. We just moved into
a house that had a Frigidaire electric range. The oven was haywire,
really tough to bake or roast with the temp settings, so replaced. The
cooktop on the range, though, was really nice. I would not have minded
keeping it if not so expensive to replace a thermostat....$150 more than
the thermostat paid for my new gas range. No bells or whistles or
automatic anything (new washer and dryer and play Beethoven's fifth:o)
Cost us $160 to run a gas line to the kitchen and then discovered that
there was something quirky about the electric line in that area, so
spent another $200 for new breaker and elec. line.....I wasn't in
trouble with the master until the electrician left :o) His friend.

FWIW, we've cooked with gas for decades and never experienced "soot and
grime." If your gas range is creating soot, it probably needs
maintenance. If you have grime problems with gas, you probably have
grime problems with electric, too.

Gas is much more controllable than electric for cooking. And cheaper.
I doubt you'll find many restaurants using electric.

A properly functioning gas cook top does NOT make "soot and grime"
It only produces CO2 and H2O

FWIW, I live in a condo where gas is not available, so that isn't an
option, even if I wanted gas, which I don't.

I have a new electric range with radiant elements under a glass
ceramic cooktop.

My premise for _possibly_ using the Pyrex double boiler is that only
simmering or boiling water (~212°F) would be used in the bottom pot,
limiting the temperature that the pot can reach. The glass cooktop,
in a sense, provides a barrier from direct contact with the electric
coils.

The old Calrod type of exposed coils will definitely cause virtually
any non-metallic material to explode.

Thanks for your comments...

I really think you need to read the owner's manual
You could also try to see if there is a FAQ at Pyrex
And if you're not sure, just use the heat diffuser to be safe

The real problem is that if the Pyrex is thin, it will heat up unevenly,
which is the time that it's at risk of breaking.

I use propane for that reason. It has been good for the past 30 years
here.

Sorry to hear you wasted that money. I've been cooking with gas for
over 60 years and never had soot or grime. You evidently had a poorly
adjusted appliance.

Sure, but that's not always possible and usually throws the cost
advantage out the window (not that the cost of running a stove is a
huge deal).

The Pyrex brand used to be borosilicate glass. The stuff they have been
selling for quite a while isn't borosilicate anymore. The new stuff
isn't as heat resistant. (Seems kinda like bait and switch.)

BEWARE: "Pyrex" is both a material AND a company name. Pyrex (the company)
makes non-pyrex (the material) stuff. The non-pyrex material does NOT
function like the pyrex material.

This is the same confusion you find with TSP. You can buy TSP-labeled stuff
that has no TSP in it!

Yeah, it's soda-lime glass now. I came across this revelation a few
months ago. It was just an inconspicuous news article among the deluge
of articles. The curious part was that the source was a report from a
glassware trade group. They usually don't say anything bad about their
industry regardless of how bad it is.

These days it is probably not possible to use your Pyrex Glass Double-Boiler on a glass smooth top range. Pyrex Glass Double-Boilers, and their related coffee pots, and tea pots were made for stove-top usage at a time when most stoves were gas stoves, which did not present a problem when low and medium flames were used. When electric coil stove usage grew, it was found that a defuser was needed to protect the cookware and to prevent breakage. The defuser lifts the cookware a bit off of the element so the heat is less direct, letting hot air heat the bottom and sides of the pot. I just checked my coffee pot and double-boiler set, and neither of them actually have very flat bottoms, something that is required for today's smooth-top ranges, but not required for most gas or electric coil ranges.

Corning was the maker of the first radiant glass-smooth top electric stoves in the early 1970's, and they supplied each stove with a set of their Corningware white-glass cookware for usage on those stoves. So it was not any ideas about "glass on glass cooking" - the stoves were calibrated for the cookware, and the cookware had polished smooth-bottoms. In any case in late 1980's, Corning sold its Housewares division - meaning it no longer makes any Pyrex or Corningware cookware - those famous pyroceram white dishes with the blue cornflower, or its stoves, etc. Corning became a company that focused on glass products like fiber optics, glass for computers, cell-phones and electronics, etc.

In any case another company, World Kitchen now makes the Pyrex-labeled and Corningware-labeled products, but they changed the formulas of the products so that they can only be used in the oven, not for the stove-top. For generations there was Pyrex BAKEWARE - the casseroles, the pie plates, mixing bowls, etc. that have the name PYREX embossed on the bottom of the dishes. From day one - these items were meant for the oven - where uniform heat surrounds the dish to cook the food. These items were never meant for the stove-top, but also happen to be what many people refer as "Pyrex" since the older doubler-boilers, coffee and tea-pots were no longer made. The formula for the Pyrex oven-ware was changed to a soda-lime type which works fine for oven-usage, and which is supposed to with-stand bumps and bruises. This soda-lime type has been used for decades by many folks without incident, and is marked clearly not for stove-top usage. Add in a few scare stories about "Pyrex exploding" via the internet and TV, and fear is generated.

So now floating around are two types of "Pyrex" and "Corningware" products - the older stuff that was clearly built and designed for the stove-top, and the older casseroles and pie-plates designed & built for the oven, as well as the newer types available in stores right now labeled "Pyrex and Corningware" that can only go in the oven. Add in the rise of glass smooth-top ranges where the makers can be sued if the instruction manuals say that a certain type of cookware can be used, and that cookware somehow "explodes". I believe that for liability reasons, because the stove makers could not always know just what kind of "Pyrex" or "Corningware" is being used on their stoves - in a blanket way state that no glass-cookware of any kind be used on their stove-tops.

Throw in glass smooth-top induction stoves which need magnetic pans - which leads to the idea that only suitable metal pans should only be used on any kind of stove top. Plus many of the current smooth-top electric stoves are calibrated for usage with metal pans, and not for the older pots that have not been produced for a long time. So the problem becomes one where if there is any damage to the smooth-top electric stove, or to the cookware - it would become the fault of the user, and the user would have pay for all repairs. So it becomes a "proceed at your own risk" type issue, where many just might opt to be safe, even if the product just might work.

All is not lost. One your Pyrex Double-Boiler is a great nostalgia piece from the days of Bewitched and the Brady Bunch. Many folks make their own "double-boiler" by using a metal pan for the bottom and a Pyrex bowl resting on top. Depending upon the size of the lower metal pan, you might be able to use one of the "pots" of the double=boiler set. In either case the bottom of the Pyrex bowl or inner pot should not touch the bottom of the pan of boiling water or actually "sit" in the boiling water, but rather rest above it, to get the low simmering that you need.

There are even ads for defuser type items for usage on smooth-top ranges. Many smooth-top ranges include a "simmer-burner" or keep-warm burner" for very low temperature tasks. I know that this message is long-winded, but I felt a better explanation and a little history was needed.

I just checked my two Corningware "Grab it" bowls that my mother got with
Green stamps (should tell you how old they are!) They say
"range-oven-microwave" on them and they've been virtually indestructible and
I've used them everywhere - even on electric ranges without a diffuser.
