I want to make a mug that is used just for drinking. I'm figuring I'll make it out of the thinnest plastic bottle I can find. Wrap the plastic bottle in bubble wrap and then foil, basically making a all in one cozy mug. The lid would be just like a traditional cozy to go over the top. I have a few questions though; what glue should I use? and do they normally use regular aluminum foil to make cozies or should I use space blanket material? Thanks.Aug 30, 2008 at 3:35 pm #1449313

Reflectix insulates well. Foil/space blanket…..not very well.Aug 30, 2008 at 6:20 pm #1449331
A piece of a foil reflective windshield screen for your car works.Aug 30, 2008 at 7:23 pm #1449338

I use the foil/foam laminate windshield reflectors as well. They work OK.
The smallest Ziploc storage container (semi-rigid, with lid) holds 9 oz, and makes a fine cup. Addition of foil/foam improves its heat holding. And it cleans up better than a pop bottle. If you want a larger sized cup, look for bottles with flat bottoms and smooth sides so you can clean them easily.Aug 30, 2008 at 7:57 pm #1449344

I've been thinking about the same. I'm awaiting the arrival of a Trapper Mug and have thought about the Reflectix/tape combo or maybe making a "koozie" out of an old 3mm neoprene rock sock (diving boot). It's wearing thin in the toe, so its days are numbered. The ankle section is fine and that's the section I'd be looking to salvage. Bonus: I never considered recycling when I bought them back in the mid 90s. A knife, a needle and some thread and I can make a pair of them!
Any thoughts?Aug 30, 2008 at 10:59 pm #1449351
Just check what the bottle's made of before you do too much work. PET or PETE will become VERY soft and unstable at 100C (Boiling water)
PE and PP should be fine (Their melt temp is around 160C)
The advantage of something like a Glad/ Ziploc container is you can punch a couple of holes in the lid and drikg through it, to prevent so much heat loss out the top of your mug.Aug 31, 2008 at 12:03 am #1449354
Changed gears. Thanks for the replies though. I got a trappers mug and the caldera system for it. I was gonna put the plastic mug inside the caldera caddy for the system I have for my titan kettle. I normally only use 1-1.5 cups of water for my cooking so I'll drop the kettle and go to the mug. I didn't realize reflectix was already a bubble wrap material I thought it was just a foil and I had to glue it to bubble wrap, that's why I asked about the other materials. I'll probably make a cozy for the mug.
Answer me this though, if I put a silicone lip protector on the mug; right at the rim and use this as a spacer to keep it that high above the caldera cone; could a small lid made of reflectix that came down over the sides of the mug a little bit be used without any issues? I don't think any flames would hit it but it would be exposed to a lot of steam and might touch the cone a little. Other than that it would be touching the silicone which wouldn't be an issue. Thanks.Aug 31, 2008 at 12:42 am #1449355
I imagine you may burn the reflectix lid as the occasional flame does shoot out the side when it is windy. As you mentioned the inner of the refectix is just like bubble wrap, so not too flame resistant. A foil lid works for boiling and will allow you to bend and store it inside the Caldera.The cozy would work well though, You could invert it and use it to hold your caldera setup together inside the trapper. AntiGravity Gear, who you can order the Caldera through can probably make you one up. I looked at customising one I had, but the result was pretty bulky, plus I don't have a need to keep my water hot for that long.

Your idea will work perfectly for a koozie. Of course, no flames aloud! :)
A used, thin ccf pad can be cut, shaped, and glued into a good one, as well. So recycle and enjoy!!!
