Why are Toilets, Sinks and Urinals Made of Porcelain?
Guest Blog by John Tarr
Have you wondered that yourself? Not only are our personal toilets and sinks in our bathrooms in our homes made of porcelain but so are most public restrooms.
We have been sitting on the same type of toilet thrones for centuries. Is there not something different that could do the same job in our modern times?
These bathroom fixtures need to be sturdy, waterproof, and in the case of a toilet and urinal, designed to be a flushing engine.
They are very efficient waste removers and there is a lot of intricate engineering behind your behind.
Vitreous china toilets (what we call porcelain) are made from clay and water. It’s a fairly inexpensive manufacturing process, which includes being poured into a mold, finished, glazed, and then sent through a kiln.
We use plastic on the seat cover on the toilet, but plastic is not durable enough to have it in the main role. Porcelain will not break under the weight of a hard landing.
Stainless steel toilets, like you see in jail, are very strong but are sensitive to temperature.
You do not want to sit on one when it is cold. Porcelain, not so much. Plus, they did not want to use something like porcelain that could be shattered and then the pieces used as a weapon in a penitentiary.
Rachel Swaby on her blog said: “Porcelain is a champ of shrugging off water. It may sound simple, but a porous material will allow liquid and bacteria in, so being impervious to both is important in a structure that’s main job is to deal with waste. The key to keeping water out, is in the porcelain glaze. After the toilet is coated, it’s fired in a kiln. Unlike, say, grout in a shower, which takes on both water and bacteria, the glaze stops bacteria at the toilet’s surface.”
A defective toilet is a bad thing no matter where you are when you need one.
In public restrooms it can be particularly annoying and unsightly so that is why Team JaniWrap invented and sells temporary out-of-order covers that can be used until the fixture can be fixed.
They are beautiful, do not take away from the overall appearance of the restroom, and are easy to apply.
People ask Team JaniWrap all the time: “Can you tell me why your temporary covers adhere so well to porcelain restroom fixtures?”
I always tell them: “It’s a proprietary blend of adhesives designed for instant tack, long adhesion, and clean release.”
