I have a lot of glass that is not quite white/clear
I have often wondered if this is the way the glass was originally or if it got “dirty” over time. I tried and failed miserably to sort this glass into general colour schemes. Here is a tip for you – wait until your glass is totally dry before trying to sort by colour; you will save a lot of re-sorting.
At any rate, I have some glass that is brown/peach coloured and I have some that is yellowish and some that is greenish. I often though that the “dirty” yellowish green glass was stained by seaweed but that does not seem to be the case.
Also as in the case of the light green or light blue glass, there is always that piece that appears brown on the yellow pile but yellow on the brown pile. Suffice to say that this glass is not very pretty and unless I find a really unusually shaped one, it will probably all wind up in some sort of cement mosaic.
I have found out that purple/lavender glass comes from manganese dioxide used as a whitener that deteriorates with exposure to UV rays. There is probably a similar cause and effect for this glass but I have yet to discover it. If you have any ideas, I”d love to do some more research.
Next time – little brown jugs and other brown glass.
