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.
It is an important factor if you do not want to have a huge aquarium in the living room. The temperature required for this species is between 75 and 85 degrees. Unlike some other types of snakes the milk snakes do not need a temperature drop at night so there is no risk you forget to turn down the heater for the night and as a result hurt the animal. The issue of feeding is not a problem. The ones living in the wild usually eat small rodents but also birds eggs reptiles amphibians and invertebrates. They also may eat other snakes like I mentioned before. In captivity the most common prey are mice. For young snakes - pinky ones for adults - adequate to their size once a week. Cue the common adage is your refrigerator running? only this time don t fall for the joke.
