Thanks for the info I appreciate it, I bet I'll find more of them in the future. That is how I usually judge price on bottles is how many I dig and since I am new at digging them I have not much to go on if I can not find many sold on the net or with google book search.
I was not aware of the term pyroglaze, thank you for the correction. I did not mean to type cream bottle, what he has are some pyroglaze cottage cheese bottles.
