Sweetened Condensed Milk Iii As Well As With Plus Together With
Because of this the value of individual bottles can range from only $10 to $500 and even higher. Additionally due of the vast variety of bottles produced it has been impossible for anyone to really do the research to determine values for them all. Due to this factor if you are interested in this sub-niche it is necessary that you be willing to take somewhat of a shotgun approach that involves some risk and this should be considered before making a final decision The only ones you should initially consider will have ALL the following characteristics If even one of these six requirements is not there do not even consider the bottle unless you are very knowledgeable about collectible milk bottles. They must be 1 quart in size They must have a round body They must be at least 8? tall They must have both a town and state name on them They must have a dairy creamery or farm name on them These town state and dairy names must be in colored (Pyro) graphics Here is how I have been buying them for the past several years.I buy any milk bottle that meets the previously mentioned six requirements if I can buy it for $20 or less.
Over the years milk has been packaged in a wide variety of different types of milk bottles. While nearly all of them are collected to some extent there is one specific sub-niche that attracts the most collector interest and that sub-niche is 1 quart Pyro-Glaze milk bottles with diary town and state names on them. Pyro-Glaze (also called "Pyro" or "Painted) refers to the method by which colored graphics were applied to the bottles. Pyro-Glaze bottles are found with various graphics & colors mostly in red green blue orange and black. They were made in several sizes and shapes but our focus here will be on a very narrow sub-niche of these bottles. These bottles were used by thousands of dairies across the country making it nearly impossible to catalog all the varieties that exist.
Casein May be defined as the major protein which is precipitated at pH 4.6 and is exclusive to milk. It is present in spherical bodies as micelles which vary in size with negative surface charge. The caseins of milk may be sub-divided into five main classes αs1 αs2 β gamma and k-caseins. In milk casein is present in combination with calcium in the form of calcium caseinate or more precisely calcium hyhdrogen caseinate. Whey proteins Are those in the whey fraction after the precipitation of casein at pH 4.6. These are the alpha-lactalbumin beta-lactoglobulin immunoglobulins lactoferrin transferrin proteose-peptone fractions etc. Most of these are globular proteins subject to heat denaturation. α-lactalbumin exists in variants A and B forms and is susceptible to denaturation by unfolding of the tertiary structure. β-lactoglobulin is identical to blood globulin and insoluble in water and is responsible for the transfer of antibodies.
