I do not write to this NG very often but when I have I've always received courteous and good answers but I have lost interest in this group because of a certain few folks that seem to have fun ridiculing others with their flame wars and childish comments. Aw, shucks, you're being too kind. Don't try to flatter us. And just who is "us"? Well, if you have to ask, not you, obviously. -- It's stupid, moronic and too fcuking obvious, as obvious as counting your fingers, so TELL ME SOMETHING I DON'T KNOW or just shut the fcuk up. - "jjs" in extremis on rec.photo.darkroom |

salvaging a developer
Otzi,
When I used the term Mylar, I was referring specifically to the metalized plastic film developed by DuPont. Its silvery surface somewhat resembles aluminum foil, but of course it is much stronger and more flexible. It is the material used for those helium baloons that stay inflated for weeks after the party. The plastic bladders I have seen in wine boxes lately are of a thick, almost clear, slightly milky plastic. I found the web site of one of the makers, but could not come up with any hard info on what the material really is. Bob ----------------------- otzi wrote: "HypoBob" How can one tell between Mylar and 'plastic' bladders?. In past decades we used wine bladders for water whilst bush walking and soon after noticed opportunists offering fancy canvas pocketed ones. However they proved very good and would last for mary treks screwed up and rescunched in the back pack before finally weeping. rarely leaking. Also with air as pillows.... They proved unbustable. As an aside, has any one found PET drink bottles to do the darkroom job? I have used 2lt ones with a car Schroeder valve in the lid to act as a compressor reservoir for airbrushing, They are good for 90psi+ although the base dimples tend to pregnant out. otzi |
