Volcanic is glassware like you've never experienced.The idea behind Volcanic starts with a glass that does not have a foot. Instead, it has an angular base that prevents the user from setting the glass anywhere. In order to set the glass down, the user must place the glass in its cradle. Upon doing so, the arms will close in and hug the glass to keep it firmly in place. When the glass is removed from its cradle, the spring-loaded arms will open back up and await the return of the glass.
