Yes; it gets old and becomes less effective. It will turn your solder lines a sort of brownish black.
You can put a dash of salt in the patina to make it more abrasive AND heat water in a separate pan or glass pyrex dish putting the patina bottle with cap on NOT tight to warm the patina up before using. It helps, but is minimal.

Why do they put lead in glass?
Lead, in the form of lead oxide, PbO, is added to glass to stabilize the matrix and improve the working characteristics of the glass. As a flux, PbO lowers the melting point considerably, and it also decreases the viscosity of the material. Additionally, lead oxide changes (increases) the refractive index of the glass.

Will flux eat away at the bottem of your fire brick forge?
Yes, flux will corrode the bottom of your fire brick forge.
How do you remove liquid lead 'faux' stained glass from a window?
If it is actual glass and not plexi-glass it's easy. Just take a straight razor and scrape it off. The only exception to this would be if it has an acrylic over coat to protect it. You can also use fingernail polish remover, it the other doesn't work.
Where is the chassis no in maruti swift vxi?
because the flux capacitor allows it to float on air
How can magnets be made by hammering in the earth's magnetic field?
It will happen in any magnetic field if the iron rod is aligned with the external flux lines and you hammer in the direction of the flux lines, and you have LOTS of patience as you may need to hammer a hundred or more times to get a "strong" magnetization. What happens (if you want to know) is the hammering joggles the magnetic domains from their previous random orientations and they gradually settle into orientations more closely aligned with the external flux lines. The same thing will happen but more effectively if the iron rod is heated to its curie point temperature and then cooled while aligned with the external flux lines. The heat allows all the magnetic domains to realign.
How do you make a stained glass picture frame?
well you need to make a pattern like draw a blue print for it then you go to a stained glass store and buy your materials and cut the glass according to your pattern or you can look up some online and print then you put copper foil on it put them together put some flux on it and solder them together BEWARE if you are only going to do stained glass artwork once or twice just buy an already made one because the machines and tools you need to buy are not cheap and you should take some classes most stores offer classes it also makes a mess dont work in a room with little children always wear shoes so you dont get glass in your foot and it will take up a whole room and a big table

Does glass have lead in it?
Some glass has lead in it, specifically crystal glass. The lead acts as a flux in glass, allowing the grains of silica sand to be melted at a lower temperature. Glasses are generally denoted by their flux, so you get soda glass, flint glass, borosilicate glass, lead crystal etc. Lead also lends crystal the attribute of a high refractive index, making it a very clear glass and also soft. It can be easily cut with designs and polished. George Ravenscroft developed the first viable lead glass.
What are the mineral categories?
They are construction, energy, fertilizer, chemical, mechanical, ceramic, glass, wood, refractory, flux, and pigment.

What is flux used for when soldering?
Flux is used to keep metals from oxidizing. Solder will not bond well with copper-oxides which are formed when copper is exposed to high temperatures (ie a soldering iron) the flux prevents the oxidation. If you were to solder without flux the solder joint would be weak and possibly completely nonconductive.
What is definition of borax?
A white mineral in some alkaline salt deposits, used in making glass and ceramics, as a metallurgical flux, and as an antiseptic.
Difference between flux linkage and flux leakage?
i) leakage flux is those flux which goes through the air and linkage flux is those flux whose go through the cell. ii)leakage flux is the loss at flux but linkage flu is warning flux. iii)leakage flux is cause of eddy current loss and linkage flux is case of copper loss.
What is leakage factor?
The Ratio of the total flux ( flux in iron path) to the useful flux (flux in air gap)
Why is a motor is a reverse function of generator?
from Faraday's laws its clear that when ever there is change in flux, an emf is produced. in a dc motor there are permanent magnets that produce a magnetic flux. If the shaft of the motor is rotated, which in tern rotates the coil that is placed in the magnetic field. Thus, changing the flux that cuts the coil. since there is change in flux an emf is induced.thus, a dc motor can be used as a generator.
Difference between leakage flux and mutual flux?
when a current flow through the coil then flux produced around the coil . if the flux linked same produced coil only then the flux is said to be leakage flux. flux produced by one coil ,but linked with another coil then the flu is said to be mutual flux.
