Anthracite is just a color name (black) used by Blanco. A granite composite sink manufacturer. I did some research & the Elkay granite sinks have a higher % of granite than the Blanco sinks. Blanco has somewhat been the leader in granite sinks, so I was surprised to see that. All the claims say they are scratch, chip & heat resistant & that they are a non porous surface so they are stain resistant also. I think it would be a good choice.

Thanks for your comment francoise. I've looked at sinks 'til I'm blue in the face. My biggest concern with an undermount sink is the joining of the sink being truly waterproof and cleaning the gaps. I don't see how an undermount sink can be truly sanitary and I worry that gunk would build up. This is strictly an opinion and in no way critical of others who choose the undermount look and installation.

To me pegasus has a different feel than the blanco, but coming from enamel on cast iron either of these will take some getting used to. I had a very difficult time finding a blanco sink and I still haven't seen one in anything other than black, but people do rave about them so I want to research them further before deciding. Scooping is when you whittle away at the cabinet sides to make the sink fit.

Ok. Glad that I find this post. I, too, am considering this One-bowl Elkay sink (Model# HD523566) because I want the largest sink I can get for my 30" base cabinet. This one is 27"; the best I can find in the market. I picked up from Home Depot. It looks beautiful, gorgeous, large and heavy. Installing is not an issue for me as my plumber will do it. I'm concerned with the rust and the upkeep that a few reviewers mentioned. I have a sink from the builder that I've been using for 18 years. I would not believe that this is a better grade than this Elkay model. I checked Kohler's website for care instructions on their SS sink and noticed that their statement is just what Elkay mentioned. So, what's the difference? I think these are standard care for SS. I just got off the phone with an Elkay rep. She said that should not happen; however, by asking her more questions, I was able to dig further. This model is an 18 gauge (the thickness) and 301 (combination of Nickel and Chromium). That level of nickel & chromium is what makes the product more resistant to rust and corrosion. A 304 is better. So she gave me a comparable model LSR2722PD - same size with a 304. The price more than doubles. My next step is to check if there really is a big difference bet. the 301 & 304 in terms of corrosion. Is that what makes the difference or are these reviewers are now noticing problems that they probably have even with their old sinks? Overrstock.com just sent me a Kraus that they have on sale for $179 which includes all the accessories. The dimension might be smaller. I would not want to go smaller because I have a fairly large size kitchen but 30 in cabinet which limits me. Will see.
