Whether its your afternoon cup of tea or accompanying cream cake: Everything looks so much more stylish on tableware you have designed yourself! And you can jazz up plain plates, cups, glasses & Co. in hardly any time at all with KREUL Glass & Porcelain Pens. Here, we answer those questions we are most frequently asked about our glass and porcelain pens. Fancy lettering or cute motifs painted on tableware will give you lots of pleasure for a long time.


My porcelain pen won't paint – what do I do?

That can happen if pigments have accumulated at the tip of the KREUL Glass & Porcelain Pens or the tip has been exposed to the air for too long. The paint dries as soon as it comes into contact with oxygen. If you go over already painted surfaces, the pigments can sometimes accumulate at the tip. So we recommend that every now and then you scribble the tip free of dried-up paint on some paper. You can also remove a clogged tip and clean it under a jet of water. Then let the tip dry and reinsert it into the pen. The KREUL range also includes KREUL replacement tips for our pens.

If you are using a new KREUL Glass & Porcelain Pen, then you first have to get the paint to reach the tip. As the paint is highly pigmented, we have fitted the porcelain pens with a valve system. So before you use the pen for the first time: shake it, pump the paint to the tip and scribble on some paper first. To do that, shake the pen with its cap on for at least 1-2 minutes. This ensures that the pigment and binder is evenly mixed. Then gently press the tip several times onto some paper until the tip becomes saturated with the paint colour. Before you start decorating your cup, etc., write with the KREUL Glass & Porcelain Pen on some paper to get an even flow of paint.

What's the best way to store KREUL Glass & Porcelain Pens?

Sure, it's handy just to keep the pens in a pen holder on your desk. But we recommend that you store your KREUL Glass & Porcelain Pens horizontally. Then the pigments settle over a larger area so you can shake them up more easily. After painting, make sure you close the pens properly. When you replace the cap, you should hear a distinct click. Is your workspace near a window? Then you’re better off storing the pens somewhere else as the rays of the sun could cause the viscosity of the paint to change.

Combining porcelain paints and porcelain pens – does that work?

Of course! Lettering or drawing next to a block of colour can look very chic. But you shouldn't mix paints from the glass jars and the pens with each other as the paint each contains is formulated on a different basis.

You fix your tableware art in the same way: Leave your paintwork to dry for around four hours. Then fire on the colours in a non-preheated domestic oven for 90 minutes at 160°C. Allow the paints to cool down and harden in the oven. All done! Exceptions are the KREUL Glass & Porcelain Pen Glitter and KREUL Glass & Porcelain Pen Clear. Only fire paint in these pens for 30 minutes at 160°C as longer exposure to heat could attack the pigments. If you combine the KREUL Glass & Porcelain Pen Glitter with other pens, then only fire your decorated items for 30 minutes. 

Are KREUL Glass & Porcelain Pens food-safe?

Our porcelain pens have not been tested for food safety as no standardized tests have so far been available. We recommend that you don’t paint on eating and drinking areas of your tableware items. So paint the plate rim rather than on the middle of the plate. Paint the outside of a cup or glass, but not the inside. Our paints are not toxic. But hot foods and beverages could cause the paint to soften again so it can come off the surfaces more easily. That wouldn’t be dangerous, but it would be a pity to lose your stylish paintwork.

What does dishwasher-safe mean?

Decorations painted with the KREUL Glass & Porcelain Pens are dishwasher-safe. So tableware that has been painted and fixed according to the instructions can be washed in a dishwasher. But not at very hot temperatures! We recommend a glassware program or another program up to 55°C. At hotter temperatures, the hardened paint can expand and come off.

For the porcelain paint to be described as dishwasher-proof, it would have to withstand daily washing in a dishwasher at very high temperatures, like, for example, in industrial dishwashers. Unfortunately, that's not the case for KREUL Glass & Porcelain Pens.
