Problem with coloured mugs?

Hi. I read somewhere that there was a problem with some coloured mugs. I use this one with no problem. https://www.printequipment.de/en/ker...gf1o4l6be8qcc0
Now the same customer wants this mug https://www.printequipment.de/en/ker...gf1o4l6be8qcc0
I read somewhere that there is a problem with this mug as the colours come off.
Anyone with experience of this happening?
Thanks

Hi Earl

The Rim and Handle mugs in the link will be fine absolutely fine. The coloured elements are applied to the mug body using high fire glazes - exactly the same ones used to produce the Two Tone mugs you've already had a good experience with. The Duraglaze coating and coating process is also identical - so all should be well!

Thanks for that info.
I tried to log onto your website to see your prices. I am registered but forgot my password. There doesnt seem to be a way to ask for my password. Can you help?
