While making a mirror requires a precise silvering process, you can make glass look like a mirror with spray paint you can find at craft stores. Spray paint can create a glossy, reflective surface that gives the effect of a mirror. Use this technique for easy, inexpensive craft projects at home.
Things You'll Need
Krylon Looking Glass Mirror-Like paint or silver spray paint
Lightly sand the glass opposite of the side you want to reflect. Clean the sanded surface with tack cloth.
Hold the spray can about 6 inches from the sanded surface and spray the surface evenly with paint.
Let dry thoroughly before moving or handling. The glass opposite of the side you painted will reflect like a mirror.
Test spray paint on a piece of glass before using it on final project to make sure you get the desired effect.
