Blonco does not ring a bell, I know the German manufacturer Blanco. This is their US website.

Yes that is the one. My spelling was off. Thank you

We're on our third Blanco Silgranit sink. The first two were white, and the current one (which we inherited in a remodel) is the deep, dark espresso color.

We love the Blanco products and wouldn't hesitate to recommend. Note that one does need to make an effort to maintain the white surface, especially around dark liquids (coffee, Coke, wine), which is true of many white surfaces. Nothing a little extra care and a bit of elbow grease can't maintain with Barkeepers Friend.

(I finally trained my husband to pour out his cold coffee into the drain rather than splash it all over the sink, that really helps keep the white clean)

thanks I think I will go this a darker one then.
