This page contains our original set of Frequently Asked Questions. When we made this mirror, clearly we did not follow the advice in the first question below. Please contact us if you do not find the answer to your question on this page or our other "About" pages.

Q. The deposit on the edge of the mirror is thin and ragged. What happened?
A. Either you did not clean edges of the glass well enough or you did not use enough chemicals. If one edge of the mirror seems thin while it is forming, you can tilt the tray just enough to get a small build-up of liquid on the edge. Hold it there for a bit to allow the edges to get equal time.
Q. Why did I see "islands" of silver floating around as the mirror was depositing?
A. Either you did not clean edges of the glass well enough or you did not use enough chemicals. If one edge of the mirror seems thin while it is forming, you can tilt the tray just enough to get a small build-up of liquid on the edge. Hold it there for a bit to allow the edges to get equal time.
Q. My silver mirror has stripes. What did I do wrong?
A. Either the tin was too strong or you did not rinse it enough. The stripes will not fade and you are going to have to clean off the glass and start over. Rinsing the tin layer well with distilled water allows the metal to form small, dense crystals that adhere evenly to the glass.
Q. My Angel Gilding has developed a wood-grained matte area. Please help.
A. You probably used plastic cups or dirty glass jars to mix the gold. Plastic cups have a release agent from the manufacturing process that contaminates the gold. You can save a lot of gold by using brand new paper cups for silver and gold. Galena chemicals will dissolve paper; use plastic or glass. Mix Copper chemicals in glass containers. The release agent in disposable plastic cups can cause the copper to blister.
Q. My mirrors have a “ripple in the sand” pattern. Why is that?
A. You didn't tilt the mirroring tray while the deposit was forming. Periodically tilt the tray gently in all directions to make sure that the deposit forms evenly.
Q. Your site has pictures of glue-chipped and acid-etched mirrors. Can I mirror over a sandblasted design?
A. You can, but a sand-blasted surface is very rough. Silver and gold on a sandblasted surface look muddy. On the other hand, galena on a sandblasted surface looks very nice – almost like wrought iron. Copper on sandblasted glass is a deep red.
Q. I glue-chipped and mirrored my glass. Now I have little holes in the mirroring. What happened?
A. You probably didn't clean it well enough after you chipped it. Small particles of sandblasting medium and/or chipping glue are stuck in the crevices and repelling the mirror. To clean the surface perfectly, mix a small amount of DrainSolve or Red Devil drain cleaner with water. Scrub the glass thoroughly with a plastic brush and rinse it thoroughly. These drain cleaners are made with lye which will dissolve the glue – and the oils in your skin if you're not careful. Wear heavy duty rubber gloves. As we said before, our mirroring chemicals are just as safe or safer than the chemicals you buy at the store to clean your house – and they are much more fun to use.
Q. Is the mirroring process affected by heat or humidity?
A. All chemicals react faster when they are warm. Mirroring works best if your shop is at least 70° F. (20° C). You can set your bottles in a pan of hot water if your shop is cold. Do NOT put them in the microwave. Mirroring is a wet process anyway so it is not affected by humidity.
