Frequently Asked Questions

Why do I need to use “Mason” canning jars?

Presto®: Pressure Canning: Frequently Asked Questions
Glass home canning jars, sometimes referred to as Mason jars, are designed for durability and reuse. They are the only jars recommended for safe home canning. Constructed of heat-tempered glass, they are able to withstand the superheated steam of the pressure canner, time after time. These special jars feature a deep neck and wide sealing surface that is essential for obtaining a tight seal. They are available in standard sizes to ensure proper processing times as specified in recipes.

Is it necessary to sterilize jars before canning?

National Center for Home Food Preservation | Canning FAQs
Jars do not need to be sterilized before canning if they will be filled with food and processed in a boiling water bath canner for 10 minutes or more or if they will be processed in a pressure canner. Jars that will be processed in a boiling water bath canner for less than 10 minutes, once filled, need to be sterilized first by boiling them in hot water for 10 minutes before they're filled.

What can I process in half-gallon canning jars?

National Center for Home Food Preservation | Canning FAQs
least one canning jar manufacturer is selling half-gallon canning jars. That manufacturer has a printed note on the top that says half-gallon jars are only used for some highly acidic foods in a boiling water canner, with instructions to call a toll-free number for the instructions. When we last called, the only choices are grape juice and apple juice, as we also recommend.

What Is That “Cracking” Noise?

Chiropractic Center of Southern Utah - FAQ
Your joints contain fluid that helps keep them healthy and lubricated (like oil in a car). This “synovial fluid” contains gas (like carbonation in soft drinks). When an adjustment is made you may hear a noise. This is know as an “audible release” and is simply the release of gas in the joint much like when you open a can of soda.

Subject: (4.2) How much are my Ball, Atlas, Kerr or Mason jars worth?

Frequently Asked Questions -- Fruit Jars
Well, the Ball, Kerr or Atlas jars tend to be fairly common. However, some jars can be worth more depending on the actual embossing. (Especially dealing with Ball jars.) Jars with unusually bright colors are worth more. These were generally made at the end of a run and contain sediments and chemicals that color the glass. Amber colored jars tend to be worth more than clear or aqua jars, but this is not a hard and fast rule either.

What does the name “Maze” stand for, or mean?

Maze FAQ [from the Atrial Fibrillation Page]

Should I use directions for canning butter at home that I see on the Internet?

National Center for Home Food Preservation | Canning FAQs
Indeed, there are some directions for 'canning' butter in circulation on the Internet. Most of what we have seen are not really canning, as they do not have Boiling Water or Pressure Canning processes applied to the filled jar. Jars are preheated, the butter is melted down and poured into the jars, and the lids are put on the jars.

What is a “warped” diamond?

DCI - Frequently Asked Questions
A warped diamond is a diamond where the sum of the crown height percentage, maximum girdle thickness percentage and pavilion depth percentage doesn’t equal the total depth percentage. (i.e. the sum of ones parts should equal the whole) A warped diamond rarely gets over 40% light return versus non-warped diamonds that can return a maximum of 91% light return. Read the article “Warping” to learn more. I’ll leave “fair” up to you but let me give you some averages.

Is “inlining” someone else’s image on you homepage an infringement?

Frequently Asked Questions
The general consensus in the copyright community at this time is that it is. There is a more detailed discussion of inlining below in the section on Retrieving and Using Works from the Interenet. If your faculty member’s desires fit within the framework of an electronic reserve, it should be a fair use. But, reserves shouldn’t be all the materials available for the course, so that might be a limitation. It also shouldn’t be available indefinitely, another limitation.

I was told I need a police “case number.” How do I get one?

City of Paso Robles: Police Department FAQs
Police case numbers are only issued when an official investigation and report is made. In order to get a case number, therefore, you need to file a report.

What is an “ideal” cut diamond?

DCI - Frequently Asked Questions
The term is supposed to signify a diamond cut to the perfect proportions for a round diamond. But since it is not a regulated term by the FTC, anybody can call their diamond ideal. For accurate proportions, for maximum light return read my article, “GIA Classifications.” NOTE: All the angles and measurements given in the article can be proven mathematically to determine refractivity, brilliance, dispersion, and critical angles.

My Bag End Infrasub-18 makes a “pop” noise when I shut it off. Is this normal?

Frequently Asked Questions
Yes. The noise is due to discharging capacitors in the amplifier. It will not harm the unit in any way. To avoid the noise, the Bag End Infrasub-18 may be left on at all times. This, also, will not harm the unit and power consumption, when not in use, is negligible. The Bag End Infrasub-18 has a built-in thermal shutdown circuit which engages when the amplifier panel reaches a specific temperature.

What does “brain death” mean?

Carolina Donor Services | FAQ
Brain death is the irreversible and complete cessation of all brain and brain stem function. It means there is no blood flow through the brain or brain stem and the patient has stopped responding to outside stimuli. It is considered death and allows a death certificate to be signed. Brain death is not the same as being in a coma, since coma patients still have brain function and respond to stimuli.

Q.: You used to make references to a “Press Virus.” What is going on in this area?

Star Graphic Supplies - Frequently Asked Questions (Page 1)
A.: It’s still going strong, and presses are becoming contaminated with stray chemicals leached from paper at an alarming rate. Laser printers and copiers are also having problems with toner drum and cartridge contamination, so I don’t think the excuse, “it’s the fountain solution or bad plates,” applies in those cases. The denial is still going strong, as well.
