Sweetened Condensed Milk Ii
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.
Udder infection promotes an increased level of chloride in the milk and depresses the secretion of lactose. Proteins Milk protein is a rich source of essential amino acids. Whey proteins are proteins that are passed along with the whey portion after the coagulation of milk. They contain 51% essential amino acids when compared to 45% in casein. The sulphur containing amino acids which are considered essential and important are found in higher concentration in whey protein than in casein. Usually the quality of egg proteins are regarded as very high. But the net protein utilization biological value and the protein efficiency ratio of milk protein come neck in neck with the quality of egg protein. Lactalbumin a whey protein whose biological value net protein utilization and protein efficiency ratio is considered superior when compared to the major milk protein casein. Normally double the quantum of vegetable protein is required to meet the daily requirement of essential amino acids when compared to that obtained from the milk proteins.
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.
