You need gap-filling adhesive/touch-up
Any imperfections, such as chipping, are considered a reflection of the hardness of Ceramic coatings and not having to rely on chemicals for adhesion. As the product remains perfectly safe for use if it chips, it does not require a replacement.
If you have a project that requires gap bonding or filling, surface repairs or laminating, the best glue for porcelain or ceramic repairs will be an epoxy. An epoxy consists of two parts: resin and hardener. When mixed together, they produce a durable, high strength bond.
We would not recommend using Gorilla Super Glue Gel for a ceramic baking dish repair.
Hot melt glue sticks are easy to use and cost-effective. Not all of them are strong enough to take on the job of bonding ceramics. Make sure to find a glue stick for ceramic applications in particular.
Chipped Dinnerware
“Even if the chip or crack in your plate, bowl, bakeware, cup, or mug looks minuscule, you must toss it. Not only are the sharp edges dangerous, but cracks in your dishes can harbor undesirable bacteria," she says.

Is it safe to drink from chipped mugs? No. Drinking from a chipped mug can be risky as the chip may harbour bacteria and expose you to harmful chemicals or lead, especially if the mug is old or the glaze is compromised. A chipped mug can also break more easily, posing a safety hazard.
Dunt: a heavy blow, a thunk, a knock. In ceramics dunting refers to cracks in pottery that occur in the kiln. Dunt is a heavy word, solid and round and a little onomatopoetic, forbidding.
Some ceramic items shouldn't go into the microwave because they have metal embellishments or trim. Some ceramics have lead glaze, which means they're not food safe once cracked or chipped, but I can't say whether microwaving them would make them more dangerous or less food safe.
Cracks or chips can indicate a problem. Damage to the dish and/or the glaze can increase the risk of moisture and bacteria seeping into the tiny cracks, which becomes unsanitary. No one wants a side of bacteria with their meals. Plus, tiny sharp pieces may continue to chip off into your food.
You can use either super glue or a 2-part epoxy. If you choose to use epoxy, make sure you mix both parts together according to the instruction on the packaging. Apply the glue to the edges of the crack and then hold the broken pieces together for a few seconds so the form a bond.

DIY pottery repair can be fun and challenging. But if you're going to try to repair your own ceramics or pottery, please do not use super glue (cyanoacrylate, Krazy Glue, Gorilla Glue, etc.). It just does not work.
The bigger question and concern was on food safety. She said they do not do perform any sort of testing for toxicity, and do not recommend that people use for fixing plates, dishes or anything else that would come in contact with food.
Fix a chipped mug by gluing the chipped part back in place. If you don't have the chipped piece, or it has shattered, use a gap-filling adhesive to fill the area. Slightly overfill the chip and allow the glue to dry. Once dry, use fine sandpaper to smooth the repair, then touch up the colour with a matching glaze.
While enamelware is extremely durable, the surface can chip if an item is dropped or gets hit with great force. If a chip occurs, simply clean the chipped area and rub the exposed metal with cooking oil to help prevent rusting. Please note that the metal is not toxic, so your enamelware is still completely functional.
And if there's even the slightest doubt about the composition, it's better to leave the crazed dishes for display rather than use. So, though crazing itself isn't harmful, it's always wise to be alert to what could potentially seep out of those minute cracks.
