Natural compounds in some foods, particularly acids, corrode metal and make a dark deposit on the underside of jar lids. This deposit on lids of sealed, properly processed canned foods is harmless.

The black or brown deposit sometimes found on the underside of a lid is caused by natural compounds in some foods which are released from the food by the heat of processing. This deposit is harmless and does not indicate spoilage.

Natural compounds in some foods, particularly acids, corrode metal and make a dark deposit on the underside of jar lids. This deposit is harmless providing the jar has a good seal and the contents have been properly processed.

Yes, metal lids are recyclable. Similar to the container they accompany, they should be rinsed and free of food residue. Additionally, they should be removed from the container and placed in your recycling container separately.

Both materials are recyclable and should be placed in the same recycling cart, unattached. At the recycling facility, a magnetic "belt" is used to separate the ferrous metals, like jar lids, bottle caps and steel cans, from the other materials. If the metal lids are left of the jar, they are not separated. In the glass handling process at the recycling facility, the lid becomes a contaminant and is not recycled but is discarded as waste.

MetaL is shorthand for Meta-programming Language. Meta-programming is a method to develop computer programs. It works by generating source code in a target language from a program specification in a higher level language. MetaL programs source code is based on XML. MetaL compiler engine can be used to generate the same program from MetaL source code to potentially any target language. Currently supported target languages are PHP, Java and Perl.

UGCs are 100% recyclable into the new glass containers. This "closed-loop" process can be accomplished again and again without the glass container losing strength or integrity. Foreign materials can damage recycling equipment and cause recycled glass to be unstable in glass furnaces. In this regard glass is no different than other recyclables i.e. introduction of anything other that the base material reduces the quality of that material.

Flattening the lids isn't a requirement, but doing so will make it easier to get them into an envelope (and will be less hassle for the U.S. Postal Service).

No. The greenhouse covering will not yellow, mold or mildew. The material will not scratch so you will not have the "cloudy" appearance as with other types of greenhouse paneling.

We would not expect the Phazyme® tablets or the intact softgels to stain clothing or fabric. However, the inner contents of the softgel may stain clothing or fabric. stated on the Phazyme® label, store at 59.0 - 86.0 F (15.0 - 30.0 C). The Quick Dissolve Tablets should not be stored outside of these temperatures. Although it is not recommended, the Ultra Strength Softgels can be stored in the refrigerator, or kept hot or frozen, as long as the softgel has not leaked or ruptured.

No. The aluminum tracks are made of heavy gauge, extruded aluminum, with a handsome powder-coated finish. The hardware is made of rugged fiberglass-reinforced resin, which has been UV stabilized to prevent yellowing or breakdown. The vinyl system is UV-treated to maintain true color indefinitely and is virtually maintenance-free.

Tooth discoloration sometimes happens from minerals antibiotic (tetracycline) or an excess of fluoride taken internally during tooth development.

The pool will with stand the test of time, the pools are UV treated and require less maintenance than a concrete pool. The pool should be maintained as per the warranty specifications set by the manufacturer.

Lids should not be used a second time since the sealing compound becomes indented by the first use, preventing another airtight seal. Screw bands may be reused unless they are badly rusted or the top edge is pried up which would prevent a proper seal.

The lids to plastic bottles are made of different grades of plastic than the bottle itself. These grades of plastic are not recyclable in Washington, and mixing lids in with plastic bottles will diminish the value of bottle-grade plastic collected in that fashion.

You can also contact your local Komen Affiliate and ask about Lid Collection Bin locations they may have or know of. Most affiliates are actively participating in the Save Lids to Save Lives program. You can also find Susan G. Komen Race for the Cure® events taking place in or around your area during the Save Lids to Save Lives pink lid collection period. You'll find Yoplait Pink Lid Collection Bins at all Race for the Cure events. Check on the pink lid itself for key collection dates.

Generally, removing bottle caps and lids is a good recycling habit, because their recyclability depends on the equipment your local recycler uses and what the lid is made of. Often it’s as much a safety issue as a recycling issue; the pressure that builds up in a sealed plastic bottle can blow a whole bale of plastic and potentially injure workers.

The familiar term Mason Jar came after its inventor, Mr. John L. Mason, who, at age 26, was a tinsmith in New York City. He perfected a machine that could cut threads into lids, which ushered in the ability of manufacturing a jar with a reusable, screw-on, lid. These jars freed farm families from having to rely on pickle barrels, root cellars, and smoke houses to get through the winter. For urban families, Mason Jars allowed excess fruits and vegetables to be preserved for use later.

Yes. Our question – what color lid do we inventory for a cup that can be almost any color? Our answer – an upscale, clear, thermo-formed lid designed to compliment the cup without clashing with the print. Some cups shown in this website are “concept” cups only and were created from DIGISPEC’s mouse pad art files to illustrate the graphic capabilities of Visstun® cups.

Met-Tile panels are made of Zincalume™ coated steel that provides excellent corrosion resistance for most applications. In oceanfront climates (i.e. within 1800 ft. of a salt water body) or other unusually corrosive environments, an aluminum substrate is recommended in place of steel. Visit the Met-Tile aluminum page for further instructions.

Your skin will not be stained. As long as you gently rub in the ointment, it will turn nearly clear. Repeated users with fair skin may see some minute grey TST particles on the applied areas. These can be removed with soap and water. As indicated above, Tetrasil is not a formof ingestible colloidal silver and therefore possible concerns of Argyria (and the bluing of skin tissue) do not apply. Please also see preceding FAQ about sun exposure.

The same things that attack wood attack bamboo as well. Generally the winter is not a problem, but you will need to protect your fence from water and sunlight as with any other wooden fence. Click the link for more details.

Discoloration is caused by improper jetting, fuel mapping, cam timing, sitting in traffic, leaving the choke on, etc. Discoloration is not caused by the pipes nor is it defective product.

No. The color is guaranteed for the life of the tile, which is 75 years. They are ceramic-fired (like dishes are), which makes them colorfast.

Light blonde and platinum hair may be temporarily discolored as our technicians feather the spray lightly into the hairline to give a natural tan effect. Discoloration of the hair will typically disappear after the hair is washed the first time after the sunless process. A hair cap is recommended to minimize any temporary discoloration.

Clear braces are of the highest quality porcelain material and do not discolor with eating or drinking. The braces are just as effective as metal braces, but they are more difficult to detect. The clear braces are more fragile than the metal braces and may not be recommended for younger children, or patients with certain types of malocclusions.
