Mug fixing with Araldite
Per an email from Araldite customer service:


  None of our Araldite® products carry food safety certifications (although there are several that would likely be safe for food contact). 
  
  Best regards

On a request for a follow-up on specific formulations that might be safe in contact with hot water, they replied:


  You could probably use Araldite® 2014, for example, but we don't have any certifications for it.
