How to take care of your kiln bricks?
Here are some ways to take care of your kiln bricks: Position your kiln on a level steady surface. If the kiln is at an awkward angle, this can put stress on the kiln bricks. This means they are more likely to crack with time. Also if the surface is wobbly, it can also put a strain on the bricks.
What to remove from a kiln?
Clean. Make sure the area is really clean - remove all flammable or combustible materials such as curtains, plastics, rags, paper, packing materials, etc. from the area surrounding the kiln.
How to clean a brick kiln?
Vacuum. Turn off the power switch! Then, vacuum all brick areas on the inside of your kiln! Make sure there is no loose fiber paper, blanket or other refractory material that is unneeded in the kiln. Extra burnout of unnecessary fiber smells crummy and may contribute to devitrification. This includes the inside of the lid, around your elements on the side, and the bottom. Your vacuum should have a HEPA filter, to protect you from inhaling dust. Ideally you would use a shop VAC with a separately purchased HEPA filter. Make sure you are using a soft brush attachment. You are vacuuming because you must remove all kiln brick dust, sand, and residue that could settle into your glass during the firing.
How to tell if a kiln element is worn?
Element wear is based on the number of firings you do, and the environment or climate where the kiln resides. Just like tires on a car, mileage equals wear. In a kiln, the hours firing are equivalent to miles. The more hours you fire, the wear you’ll see on your elements. The thicker the gage of the element coil wire the more resilient the element will be. Keep in mind that each manufacturer has taken great care to size the element coils for the amount of amperage that they will carry to get the job done well. If you find it necessary to change out your elements, make sure you speak to the manufacturer to determine the appropriate element size for your kiln. Please refer to your operator’s manual for the discussion and photo's of "Element Replacement".
What is the protective coating on a kiln lid?

How to hold a cement job?
For a cement job to hold, you need to clear out any dust and rubble that will prevent the joint from being tight. If the break goes back together tight, then do not remove the broken piece because it may just make it worse, and you may not be able to get it in and out easily because of the element holder anyway. If it fits tight as is, just try to work some fairly fluid cement into the crack and then push it together.
Can you inject thin cement?
Neil’s got a nice idea in that injecting some very thinned cement might actually be less risk. Maybe inject or spray a little water into the crack first and inject your thinned cement. A small syringe could work great. Everything should wipe nice and clean with a damp sponge at the ready to wipe off excess / drips.
Can you mix kiln cement?
I am a big fan of buying kiln cement is powder form, rather than liquid. You can mix up the small amount that you need, and the rest can be stored indefinitely. I have bought small jars of liquid kiln cement before. It works great right after you buy it, but when you reach for it again a year later, the liquid has turned into a solid rock.
