Q&A for How to Make a Mirror

All you need to make a mirror is a piece of glass and mirror-effect spray paint!

It does actually turn it into a mirror, so you should see your reflection. Check the cap, for example --you should be able to see a bit of a reflection in the cap alone.

Yes, by using spray paint. But make sure your spray paint is metallic and glossy.

Mirror paint is a special type of spray paint that looks like a mirror when you apply it to glass. It won't look like much until you actually flip the glass over so that the paint is on the back. It is more reflective than regular silver-colored spray paint.

Yes, many items are made this way. Some plastics, like clear poly carbonate, look like glass mirrors, and some are even double coated so both sides serve as mirrors.

No, the wood will absorb the liquid and maybe leave a "dented" or rough mirror.

You don't. Normal mirrors (not DIY) are made by sputtering a thin layer of (usually) molten aluminum on glass in a vacuum chamber and then coating it with waterproof paint.

The other option is putting molten aluminum onto glass inside a vacuum chamber, so mirror spray is the most effective option to do at home (and works almost as well).

Use a concave glass panel and follow the steps above. Purchase a concave glass panel from an architectural supply store, or if it's going to be small, a glass blower can shape it to concave dimensions.

You can buy it in an arts and crafts store, or you can buy it online. Other brands may also make looking glass paint. Search for terms like "mirror effect" or "mirror paint."

You would first need to apply mirror paint until you have a partially reflective surface (semi-silvered mirror) against a black backdrop.

Remove the silver backing using a scraper and a solvent, such as "Mirror Remover." Next, follow the steps in the article to apply a new silver backing using mirror paint.

When that has happened, it usually means the actual product allowing glass to become a mirror is damaged. It needs to be repaired by a professional, as it should be carefully scraped off the mirror's back, then have the specialist reapply a new coat of product. Doing this yourself will be hard, dangerous and you will most likely damage your mirror.

It would be more transparent to use glass than plastic. If it was a very clear plastic, it would work better.
