Hello Kurt; I use a free picture handling software called 'Irfanview' it works great for everything and is fairly easy to use for resizing. Regarding your bottles, the most important things to learn about are pontil marks (the blow pipe - tube pontil marks), which have left an open tube of glass from the blowing of the previous blown bottle that was left on the previous blow pipe. From there the marks left by the use of an iron punty or puntee rod, which was coated with sticky dirt, red lead, graphite paste. and/or white lead paste, and then powdered glass, iron powder from mold shop machining, or sand that would stick to the glass product to let that punty rod be the handle for finishing the top of the bottle with applied glass. Looking at the bottoms of you bottles you should learn to recognize those marks. The next thing is to look at the top of the bottle. If the mold seam comes up over the finish on the bottle - it is good for recycling unless it has some unique characteristics. If there are horizontal tool marks from the shaping of the finish they are keepers, if there is extra sloppy glass below the finish that was pushed down and left there - they are keepers. The quality of embossing that was hand cut in the molds that you can realize are crude and unique should be saved, embossing that is in a slug plate oval or round ring enclosure should be evaluated. Lettering that has little dots from a venting drilled hold should be evaluated. There are certain types of bottles that should be set aside - and I can't take the time to list them here. Good luck checking them out. If you want to question me more - send me an email. RED Matthews
