Glass can be recycled forever until it gets contaminated.
There is no limit on the number of times cardboard can be recycled. Cardboard will lose it's integrity as it is continuously recycled though.
Seeded Glass has pinhead sized bubbles. The glass softens the light coming from the bulb inside and replicates the naturally seeded glass made in colonial times.
The mechanical advantage of a machine is the number of times it can perform the same task without breaking down.
It depends on what glass is used to make the insulated window. Most often 1/16ths" to 1/4" glass is used, sometimes asymmetrically. The spacer and air space weight is negligible. The difference between tempered, colored, low e and clear glass is also negligible. If 1/16" glass (called single strength - 1/8th inch is double strength) is used then the window will weigh .85375 per square foot (height times width) times two (each side). Or to make it easier just use the total size together, i.e., 1/16th glass plus 1/16th glass on each side is 1/8" thick overall or 1/4" plus 1/4" is 1/2" overall. Glass weights: 1" = 13.5 lb/sq', 1/2" = 6.75 lb/sq', 3/8" = 5.063 lb/sq', 1/4" = 3.375 lb/sq', 1/8" = 1.6875 lb/sq', 1/16" = .85375 lb/sq'. A one foot square insulated window made with 1/4" glass each side will weigh about 6.75pounds.

Glass can be recycled forever until it gets contaminated.
Simply because glass is tougher than plastic - and can be endlessly recycled. Many plastics deteriorate if they're recycled too many times.
Glass can be recycled almost indefinitely, so long as the glass is not contaminated in some way. If you're specifically asking if you turn one glass item in and how many times will it be recycled and reused in that year, the answer will probably depend on where you live, but I'd say 4 to 6 times. This is based on the statistics that show it takes about 8-12 weeks to recycle glass and put it back on the shelves, and 52 weeks in a year.
Since glass is a fairly stable crystal in the short-term, it can be recycled (melted and reformed) many times before the original silica is lost to slow wear.
thousands times
A cartridge can be recycled depends on the form in which it is used but generally it can be recycled in 2 to 3 times dependent on the type and brand we possess.

paper can be saved by making the paper into Recycled .paper can be recycled upto 6-7 times.

Every time paper is recycled, fibers damage due to mechanical and chemical operation. How many times can paper be recycled? Ans. Unbleached (brown) paper such as corrugated boxboard which does not require any de-inking can be recycled 10-20 times. Bleached grade papers such as newspaper, office waste etc. which will require de-inking can be recycled 5-10 times.
