23 Sep Ceramic plates and mugs decorated with Pop Art design
Did you know that your “food” ceramics could be toxic?
How many times have you bought a mug, a plate, a set of ceramic cups or other objects that can be used for food, at the local party stalls, at the markets when you’re on vacation or on the internet?
Have you ever looked at the bottom of the object to see if there are any symbols and which ones?
Yes, because ceramics, like glass and other food materials, especially when it has decorations, must be certified using symbols that guarantee its use for foods, such as these:
This is a mandatory procedure for those who produce ceramics for decorated foods either by hand or through digital or industrial techniques, yet in most cases ceramic souvenirs or gadgets are not up to standard!
This means that after the decoration, the ceramic object “for food” has not been subjected to an adequate cooking cycle which, through the last of the processes, namely vitrification, makes it compliant and safe for our health.
The cooking cycle in fact lasts many hours and vitrification is essential to prevent the solid or liquid food from coming into contact with the glazes used for decoration, which among other things must also be free of lead in compliance with the regulations current.
Temperatures generally go well beyond 1000 degrees due to the structure itself that the ceramic product must have and for vitrification.
But not everyone can do this because they need professional ovens that have an important cost and that above all use the artisan craftsmen or potters who produce the object itself.
While those who merely decorate and market gadgets or souvenirs use smaller ovens that cost much less because they reach decidedly lower temperatures and for this reason they do not allow the decoration to pass below the vitrification, leaving it on the surface and in contact with food.
Knowledge of these physical and chemical dynamics is essential for those who are in the process of working or marketing ceramics: it means having in mind what the final result is to be achieved, whether a furniture item or a food product.
The majolica plates of PIT-POP in fact, although decorative and out of reach, are suitable for food use and made with raw materials, enamels and lead-free colors in compliance with EC directives.
They are produced, glazed and decorated in the traditional way and combine the skill of the artisan with the modern digital technologies.
In particular, the application of the design is done through a digital decal. They are 100% Made in Italy.
All this also explains the costs between a stall product and a product of excellence.
And you? Are you using a mug at home, a food dish without these symbols?
So we don’t tell you to throw them away, especially if they have a value for you, maybe you can use the mug as a pen holder and the dish as a pocket emptier, but certainly not for drinking tea or eating spaghetti!
