Question about sap wood

Photo posted on a.b.p.w
I picked up these book matched slabs from a new sawmill for a conference
table I've been commissioned to build and was asked an unusual question
about his kilning process. He asked me if I was not concerned that the wood
was not steamed which is something I've never heard of. He said some bigger
outfits steam the wood and then the heartwood color bleeds to the sap wood
producing one solid color throughout the entire board. so my question is
this; How do you tell if a board has been steamed and what affect if any
could it have on the outcome of a project?

Thanks,
EJ

Without looking at the pics I assume they are walnut or cherry. Almost
all large drying outfits steam the walnut and cherry. Steaming does
just what the man said, except it doesn't completely eliminate the
difference between the sap and the heart. It leaves the sapwood a dirty
yellow color. Mills do this so they can sell the sapwood at the same
price as the heart and not defect it out as they do with other
hardwoods. Some people like the contrasting wood colors, I do not. I
do not like steamed walnut because it bleeds the other colors out of the
heartwood also, leaving a muddy, monotone color to the heartwood. I dry
my own walnut for my rockers and cut out the sapwood. Steaming has no
effect on the outcome except for the appearance.

Normally I cut it out as well but the customer particularly liked the
figuring. It definitely made joinery more difficult. Kinda like a piece of
balsa wood sandwiched in there. So in the future I'm looking for
muddy/mottled color? I also think this is an indication the this new sawyer
is a stand up guy.

Thanks,
EJ
