Quote from: morticaixavier on April 20, 2012, 11:53:06 amI don't boil in them but I use .5 gallon mason jars for my starters. Once I get organized I intend to run off some extra wort from each light colored mash and preasure can 1 quart per half gallon jar so it's just a matter of pulling the jar out of the cupboard, cracking the seal, pitching the yeast and done. Drop the dome lid losely on top and I won't even need sanitized foil. my preasure canner will handle 2 or 3 half gallons which is really all I should need from any given brew day
You're using a stirplate with the mason jars? I thought their bottoms were concave.
nope, don't use a stir plate. I shake it up everytime I walk past and my wife has standing orders to do the same. I don't know that I beleive that you really get much o2 into the wort with a stir plate, particularly in a flask. I am sure there is some but I feel like a good shake now and again will get the air above the wort more saturated with o2 than the constant gentle spinning of the stir plate. I have 0 science to support this however.**EDIT to be pedantic about my own post**I suspect that 'more saturated' is not a valid phrase in the same way 'more unique' is not valid. I appologize.Also, in reference to the SWMBO thread, Let me change 'Standing Order' to 'Standing Request'

Sorting through nerdy jargon: how to sound like a real scientist. Many people outside the science world use the terms ‘flask’ and ‘beaker’ interchangeably. While both tools are often used in a science lab, they are actually quite different.
Flasks are notable for their unique shape: a rounded vessel and a cylindrical neck. Flasks can be used for holding and measuring solutions, as well as for chemical reactions and phase changes (heating, cooling, etc). Flasks are normally the site of chemical reactions, for the reaction can take place in the large vessel and have low risk of spilling due to the long, narrow neck of the flask. Furthermore, flasks have the ability to be capped or corked, therefore solutions can be held for long periods of time without risk of spilling.

Beakers, on the other hand, are cylindrical containers with a flat bottom and a spout on top. These are also used when performing experiments, to hold various liquids for either mixing or disposal. The main differing characteristic between a flask and a beaker is that beakers have straight sides, rather than slanted sides like a flask. Beakers are mainly for measuring and transporting liquids from one site to the next. The spout on beakers makes pouring their contents easy, which makes them invaluable for performing experiments.
Flasks and beakers do share some characteristics. Both are made from either glass or clear plastic, most are graduated- meaning they have markings on the side indicating the amount of liquid they contain. Both are used during chemical reactions, and both are essential to a successful lab.
We hope this brief crash course in science lingo helps you to sound smarter among your peers. Until next time, happy culturing!
