I have this Crown pint sized jar. Red book 686. The only pints listed are aqua, clear, SCA, and apple green. Looks more yellowish to me. Would this be considered sediment amber? I appreciate any input. Thank you.
I think that's clear glass which has been exposed to plenty of UV radiation over the years. The selenium in the glass will slowly turn yellow when exposed to UV rays. It's a slower process than the manganese turning purple but I think that shade of yellow could be reached if it was sitting in the sun for a few decades.
Have to agree with a previous poster that this is likely the selenium reaction in the glass. Similar to manganese and the pinkish purple effect you get. Everyone has their definition of color, but to most jar collectors, this would be straw yellow.
