MOUNTAIN VIEW -- After selling out of its off-white models of Google Glass within hours Tuesday, the search giant planned to end its one-day sale of its $1,500 Google Glasses.

At one point Tuesday, Google told this newspaper that it might extend its offer to sell the wearable computers, but later in the day decided to end sales.

Although Google has no intention of revealing how many units it sold Tuesday, the company said on its Google+ account, "Wow, what a morning! We're happy to see so many new faces (and frames) in the Explorer community. Just a quick update that -- ack -- we just sold out of Cotton, (a color of Google Glass) so things are moving really fast."

Google Glass allow its users to use voice and touch activation to access many of the same tools and toys enjoyed by smartphone, laptop and tablet users -- except in a lighter, wearable package.

Until Tuesday, an estimated 10,000 units have only been in the hands of people hand-selected by Google, dubbed Explorers.

While many are curious about the capabilities of Google Glass, some of the early adopters have reported angry confrontations over the wearable technology's ability to surreptitiously record and shoot images and instantly upload them to the Internet.

Google has said it hopes to bring Google Glass to the mass consumer market sometime later this year. So it was unclear what Google was trying to accomplish by offering an unspecified number of units for a limited time -- for a cool $1,500 each, not including tax.

But J.P. Gownder, vice president and principal analyst with the Forrester tech research firm, told this newspaper that Tuesday's sale will give Google prime market data on the demand for Google Glass.
