I feel our current sink is on the small side. The larger sink lets us
process things in trays in the sink (even for large format stuff) rather
than on a countertop. Every darkroom I've seen follows this convention.
It makes it no biggie if you spill things and minimizes time and effort
during prep and cleanup. <br>
<br>
I know there was at some point a suggestion to build a work surface with a lip that
drains into the small sink, which would be great but I think getting a longer sink is a lot
easier..<br>
<br>
I also think the extra 3" depth would do more good than harm. <br><br>So to recap... Vinyl sink has 2 yays (me,miloh), 1 nay (Kelly), 1 "not strongly opposed" (Ben), and 1 maybe (Sean?)<br><br><div class="gmail_quote">

<p>So the vinyl sink is probably okay for most things that would be safe to do in the darkroom. It's stable to most common acids and bases in reasonable concentrations and most moderately strong oxidizers like peroxides. It has terrible performance for organic solvents, but I wouldn't recommend using most of them in the darkroom anyway. Those require a fume hood, not just a well ventilated room. The only solvents that would be reasonable to use in that room which vinyl is incompatible with are acetone, ethanol and isopropanol. The first and last are nail polish remover and rubbing alcohol, respectively and I assume that you all know what sorts of things you find ethanol in. These will pretty much dissolve the sink. On the other hand the stainless steel will be stable to these but eventually corrode with acid or bases. Although this can be minimized by pouring these solutions into a stream of running water to dilute them (although I donlt know if we can pour these down the drain at all or need to collect them in chemical waste bottles and dispose of them separately).<br>
I am not strongly opposed to the vinyl sink since we can probably figure out other ways to deal with those few solvents which might destroy it. I think the size might be an issue though, that space is really tight.</p>

<br>27" is only 3" longer than what the currently planned space for the table is...don't know if that really kills it or not.<br><br>My big question - does this particular sink offer us some benefit that the stainless one will not (i.e. is there a really cool reason for us to get the defacto darkroom sink instead of the one thats already sitting in the space)?<br>
