I have a lot of customers who love the matte look of etched beads. Sometimes, the customer doesn't ask to have them atched, but realizes when the beads arrive, that they'd like to try the etched look. So I give the customer the option of sending them back to me for free etching, or trying it themselves. Here are some instructions for beaders and beadmakers on how to etch your own beads.
First, you need to purchase a small jar of etch solution. I recommend Etch All Dip n Etch, or Etch Bath. These are usually sold at any craft store. The people at the store will usually know what you mean when you ask for glass etching solution.
Once you have the solution, you need to wear some disposable gloves, and be in a well ventilated area (kind of like when using cleaning supplies). The etch solution is acid, so it's a good idea to have some baking soda around to neutralize the solution if it gets on anything.
Use a plastic cup or bowl, place the beads in and then pour the solution over them until they are covered. Alternatively, you can string the beads on something non-metal and just pop them in the jar. Leave the beads in the solution for 5 or 10 minutes (read the bottle label - some solutions are different). Then, using a plastic spoon, scoop the beads out and rinse them completely. You might want to put a few spoons of baking soda in the rinse water with them to neutralize.
You can then pour the etch solution back in the jar to use again (it can be used over and over for about a year). A plastic funnel helps.
Don't use glass or metal utensils. Don't get the etch solution on anything porous, including skin or cloth. Wash immediately if you do get the solution on anything.
The beads may have a white dust on them after etching. To remove this, you can use a toothbrush and soap and water. I hope this helps!
