Is It Safe To Superglue A Mug?

We’ve all been there; one careless movement while doing the dishes, and suddenly you watch in horror as your favorite mug – or your only mug – breaks into chunks in the sink. The only thing you have is a tube of Super Glue. Will it work, though? And is it safe to use on a mug?  

If the Super Glue contains cyanoacrylate, you should not use it to fix your mug. Cyanoacrylate is an ingredient in most Super Glues and is a toxic substance and therefore not food safe. If the cup is used for decorative purposes, Super Glue is a great option to consider.

Let’s go through the ins and outs, the dos and don’ts of choosing the best Super Glue to fix your mug – and the ones best steer clear from.

Can I Use Super Glue To Fix My Mug?

Super Glue, invented in 1942, is a fast-acting, long-lasting adhesive used to fix everything from ceramics to toys and even shoes. But is it food safe? Will it hold? Will you still be able to drink your coffee from the mug and what if you have a dishwasher?

When choosing Glue, make sure you have the best product for the type of material and its intended use. While it may seem that any glue would work for the job, there are a few things you should consider before applying glue to kitchenware, for instance:

  • What materials are you trying to glue together?
  • Will this item be used to hold foods or liquid?
  • Is the glue heat and water-resistant?
  • What are the ingredients of the glue?

The Dangers of Cyanoacrylate Adhesive

Super Glue is fantastic and can be used to fix just about anything, but there are some hidden dangers. Most Super Glues contain cyanoacrylate, a potent chemical responsible for the fast-bonding characteristic of Glue. It is, in fact, a toxic chemical that can cause significant injury and illness when ingested or gets into contact with the skin.

Cyanoacrylate is not a food-safe glue, which means we should not use it on any items holding food and liquids because of possible chemical leakage. Superglues that contain cyanoacrylate are not FDA approved for use on kitchen items due to the toxicity of the adhesive. When choosing Super Glue, always look at the ingredient list and select a glue that does not contain cyanoacrylate.

Cyanoacrylate can cause the following symptoms when ingested or if it gets onto your skin:

  • Skin irritations
  • Nose and eye irritation from glue vapors
  • Asthma-like symptoms
  • Flu-like symptoms

Avoid using Super Glue with cyanoacrylate on any kitchenware items that you routinely place in the diswahser or microwave.
