Insulating a pyrex cup

Recommended Posts

I remember a post a long time ago that someone, poured POP around the outside of the cup to help keep the heat in the cup. Has anyone done this and if so does it help? The reason I ask I pour in a cool basement, and have to nuke the plastic often to keep it warm.

In the colder climates we have what's called pipe heater tape or pipe warmer. It's an insulated electrical heater that looks like electrical wiring with a male plug on one end. We wrap this around water pipes that are in danger of freezing in the winter.

Surprised I never thought of this before.

One could just inbed this in the plaster around the dipping can and then just plug it in.

It won't get hot enough to melt the plastic for pouring; but it will slow down the cooling process quite a bit.

You folks down south might have difficulty finding this locally but I'm sure you could order it in. It's not an exspenive item.

I'm not pushing any of these companys. I just did a google and came up with this list which looks promising.

I just took a gallon milk jug, cut it in half, then sunk my 2 cup pyrex cup in the center after filling the milk jug halfway with pop.

I had to put some balanced weight in the cup to keep it down in the pop.

I would guess the thickness is about 2-3 inches on all sides.

Yep, Jim is rite I made one per Jim's advise and it works well. Very cheap and easy to make. I live in Arkansas where the weather changes hourly this time of year. So if it is really cool out or just plain cold, I use a heat gun at a short distance to warm the pop warmer before putting the pyrex into it. If not the pop could crack or your cup explode. They do work great though. Jim knows his stuff.

Thanks Shane but I take no credit. The idea came to me when Dave and Nil were talking about the insulative properties of pop vs aluminum molds.

They provided the light bulb!!!!

I think you're wrong there Jim. I think every contributing member of TU can take credit for the ideas that any member can take advantage of.

The free exchange of ideas is what makes TU the very best site of it's kind on the net.:yay:

I enjoy watching how someone will come up with something and during the discussion someone else will say something that takes the origional idea to another level. It's like the post takes on a positive life of it's own.

I do thank you for the acknowledgment and I' sure Dave does as well.:tipsy:

Then the cup is not fully insulated? Its only partial? what if you taped the handle opening up then poured the POP leaving the POP about an inch from the top of the handle (enough to get your finger in to lift it out) then took the tape off after the mold set up? It would leave the entire handle cavity open. Would getting more height with the POP insulate it any better? Just a thought.
