KREUL Classic glass and porcelain pen, medium or fine

Write a name on the outside of a cup, add a dotted border to a vase or outline a small motif. KREUL Glass & Porcelain Pen Classic gives glossy, opaque, water-based colour. You receive one pen in your selected colour and tip style; the decorated object is not included.

Choose colour and tip

The eleven colours from signal yellow to black have a round medium tip of 2-4 mm for clear lines, lettering and dots. Black is also available with a fine 1-2 mm tip for smaller lettering and outlines, so select the tip as well as the colour when choosing black. Classic is opaque: a drawn line does not remain transparent on clear glass. The colour chart and example photos also show other styles; they are not sets included with your pen.

Prepare and start the pen

Use a smooth, heat-resistant glass, porcelain, ceramic or metal object suitable for this oven treatment. Wash it by hand with washing-up liquid first and leave it clean and grease-free. Cleaning in a dishwasher beforehand can leave a water-repellent layer. Before each use, shake the pen vigorously for 1-2 minutes with its cap on. Gently press the tip onto paper a few times until colour appears, then start writing on the paper. Do not pump directly onto your object.

Make your own line sample

On a suitable sample, draw a letter, a row of dots and two curved lines side by side. Compare the available space with the tip width before drawing the full design. Too much ink? Stop pumping and write on paper first. Before oven curing, mistakes can be removed from a smooth surface with water. Record colour, tip and surface, then assess your sample after curing and washing.

Drying and oven curing

Let the drawing dry for 4 hours. Place the object in a cold oven and heat to 160 °C. Start the 90-minute curing time when 160 °C has been reached. Then let the object cool and harden inside the oven. Use only an object that can withstand this heat. This timing is for Classic; other pen ranges can require different curing times.

Care and safety

After correct oven curing, the decoration is waterproof and suitable for dishwashers. Leave drinking rims, interiors and cutting or eating surfaces that contact food or drink unpainted. The ink contains benzisothiazolinone and chloromethylisothiazolinone/methylisothiazolinone and may produce an allergic reaction. The ink is harmful to aquatic life with long-lasting effects; prevent ink residues from entering the environment.
