Never burn your mouth again.
Enjoy your hot beverage for hours.

Have you ever burnt your mouth on that first sip of coffee? Have you ever struggled through that last bit of tepid tea?

This is the mug for you.

Temperfect mug cutaway

The Temperfect mug brings your freshly-brewed beverage to the perfect drinking temperature within minutes, and, using the energy it stores, it maintains that temperature for hours. It requires no batteries or cords, and it’s infinitely reusable!

Temperfect Mugs add an extra layer of special insulation to a standard double-wall travel mug. The Temperfect insulation absorbs the excess energy from your hot beverage. This means your drink will reach the perfect temperature quickly, and you can start enjoying it right away.

Temperfect operation

Pour your fresh-brewed beverage in, the Temperfect insulation absorbs the excess heat

In about 2 minutes your drink is at a comfortable drinking temperature

The Temperfect insulation slowly releases the heat into your drink to keep it just right for hours

This excess energy is stored in the insulation layer and released over time to keep your drink at the optimum drinking temperature for hours.

You won't have to wait to enjoy your drink, and you don't have to rush to finish it before it gets cold.

Get a Temperfect mug and join us in Hot Beverage Bliss!

We used a Kickstarter campaign to help us buy the tools we need for the manufacture of our Temperfect mugs. That campaign ended in January, 2014 and was a resounding success. We are now working full time getting mug production underway. Our initial estimated ship date was July, 2014, but we've had numerous production delays. We're now expecting to begin shipment in the first half of 2015. Follow us on facebook or twitter to keep up with our progress.

If you missed the Kickstarter campaign you can still pre-order a mug any time. These pre-orders will be fulfilled after the Kickstarter mugs ship. If you order now you will get your mug as soon as possible, and your credit card won't be charged until we ship it.

Javabliss 16

The Javabliss is a 16 oz. travel tumbler designed to fit perfectly in your car cup-holder. It has an easy-to-operate shutter on the lid to keep your drink from sloshing out. The rim of the lid is designed to have a pleasant lip feel, like that of a ceramic mug, and the tumbler's triple-wall design gives it the heft of ceramic. All the Javabliss tumblers have polished high-grade stainless steel interiors so that they are easy to clean and won't retain odors or taste from your last drink. The tumbler body is not dishwasher safe (because of the insulation used), but the lid is easily disassembled for cleaning in a dishwasher. And of course all Javabliss models have the Temperfect insulation that keeps your hot drink just right.

black oxide finish
ships 1st half of 2015

This version of the Javabliss mug has a beautiful, smooth, brownish-black sepia finish, the result of a chemical reaction between the stainless steel and an alkaline aqueous solution. It is a robust finish that resides in the pores of the metal, not on the surface like a transparent lacquer. It has an interesting, somewhat mottled appearance, changing depending on the light, like no other mug on earth. The darkness and color of the finish are somewhere between those of the photograph and of the render in the image above (see also the photo of the engraved version below). These mugs will have a bead-blasted droplet logo, and no sleeve (though we'll be glad to furnish one). The lid is high-gloss white. $160 plus shipping. Expected delivery: first half of 2015.

Titania Finish

Titania ceramic finish
ships 1st half of 2015

Titanium dioxide, or Titania, is a coating used in industry for insulation from extreme heat (in gas turbines, for example) or for parts that need an extremely wear-resistant coating. It is a ceramic, and it is applied with a plasma-spray process in which it is heated above its 3,400°F melting point and sprayed onto the mug surface, building up a layer of material from 0.003-0.007" thick. The finish has a fine roughness, like that of bisque-fired ceramic, or slate, and even when wet it is not slippery. Because of the roughness, it builds up an interesting patina of scuffs with use (not scratches, it's too hard for that), so it is not a coating for someone who wants perfect uniformity. This is also a chameleon coating that changes color depending on the light, surroundings and observer. It can appear to be black, dark blue, gray and all colors in between.

Titania finish colors

On these mugs the droplet logo and base are masked during the spraying process so that the underlying stainless steel shows through, as in the rendering above. The lid is high-gloss white. $280 plus shipping. Expected delivery: first half of 2015.

Engraved Black Oxide Finish

We are offering a select, artistic version of the black oxide finish mug, with hand engraving by a local Raleigh, North Carolina artist, Dustin Walker. Dustin is a metalsmith who makes unique designs, and for this project he will be creating a different, beautiful, engraved pattern for each mug. The engraving will be applied to the surface of the mug in a band encircling the bottom as shown, and each of his designs is exclusively one of a kind. $400 plus shipping. Expected delivery: first half of 2015.

Questions & Answers

How do I use the Temperfect Mug?

Just like any other mug! The special insulation layer does the work for you so you can enjoy your beverage.

Does it matter what temperature my coffee is at initially?

The Temperfect Mug is designed to work best with your beverage right after brewing because it uses that excess energy to keep your drink just right. We measured an average serving temperature of about 175°F coming out of coffee makers and for tea and coffee served at shops, so that's the temperature we use for designing our mugs. If your drink is at a different temperature, the mug will still work fine!

Is the insulation layer safe?

The insulation layer is non-toxic and completely safe. It is sealed off from the beverage so the two will never come into contact.

How long does the insulation layer last?

The insulation layer lasts for the entire lifetime of the mug; it will never lose potency or leak.

Can I put the Temperfect Mug in my dishwasher?

The lid for the Temperfect Mug is dishwasher safe, and is easily disassembled for thorough cleaning in the dishwasher or by hand. However, the main body of the mug is not dishwasher safe. It is made of stainless steel, and requires only a rinse after use in most cases. The inner surface of the mug has a smooth finish which will not retain flavors of your last beverage.

Does the Temperfect Mug keep cold drinks cold?

The Temperfect Mug will keep cold drinks cold for hours due to the vacuum insulation layer. You can even pre-cool your mug in a refrigerator for even better cold-drink performance.

Currently Enjoying: Angela's Teas Dung Ti Oolong

As a sensitive lipped individual, I would brew my tea and then have to stare longingly at the cauldron of undrinkable lava I had created. By the time I was brave enough to sip it, it was often a little too tepid, and I would only have a few moments to enjoy it before I was drinking glorified shower water. In my senior year at NC State University I took on this problem as a senior design project and started crafting prototypes. Right after graduation I was pointed in Dean’s direction by another Raleigh entrepreneur. Dean and I met and decided to join forces; the rest is history.


Currently Enjoying: Lupicia Sencha from Uji, Kyoto

I started working on this idea in 1995, when I was still using a simple ceramic coffee cup. I would carefully brew a perfect cup of coffee, and then set it on my desk to wait for it to cool some before drinking. Often, though, I would forget it, and when I remembered it again it would be cold. Even when I did catch it in its temperature sweet spot, the drinking pleasure was far too short. I thought about ways to bring the coffee quickly to a comfortable temperature and then keep it there, and came up with the solution used in our Temperfect mugs. I worked on this idea for 15 years, learning along the way to make these coffee mugs myself. They work great, and, following a very successful Kickstarter campaign in 2013, I am now making them available to the world.
