More than half a million glass mugs have been recalled after they began to break when filled with hot liquid, dunking coffee drinkers in scalding liquid and cutting their hands.
So far, the company behind the mugs, JoyJolt, has heard from 103 people who reported that the mugs broke upon contact with a hot liquid, which is exactly what they are designed for.
Dozens of people have been injured by the use of defective cups, suffering burns and lacerations all over their bodies. In some cases, people were injured so severely that they required surgery.
JoyJolt is a popular glassware company that sells many similar products, including mugs, wine glasses, and champagne flutes, but this recall only applies to their Declan 16oz single-wall glass mugs.
The recall affects JoyJolt’s Declan 16oz Single Wall Glass Mugs (JG10242), which broke upon contact with hot liquids.
According to JoyJolt: ‘Our Declan 16oz single wall glass mugs may not hold up to heat as well as we expected, increasing the potential risk. So let’s do it right.
‘To date, we have received 103 reports of such incidents out of 580,000 mugs sold. “Your safety is our top priority and we are taking immediate action by issuing a voluntary recall for this product.”
Users can contact the company for a refund.
Of the 103 cases of broken vessels, 56 people were injured, including 35 burns and 21 cuts.
Seven people had to go to the hospital to receive medical care, including surgery and stitches for the injuries they suffered.
The products were sold through Amazon and the company’s website from September 2019 to May 2022 for between $20 and $25 for a set of six mugs.
Most JoyJolt mugs are double-walled glass, which has two layers of glass surrounding an insulated air pocket.
Declan mugs, however, are single layer glass. Glass is very sensitive to temperature changes and adding hot liquid like coffee can cause uneven contraction and expansion of the glass, causing it to break.
This is not the only cup recall that has occurred this year. In March, more than 440,000 Starbucks cups were recalled after customers reported they also overheated and broke.
There were 12 reports of ceramic- and metal-coated mugs malfunctioning, resulting in 10 injuries, including severe burns and blisters on customers’ hands, as well as cuts to their fingers.
