You can't make it. You used to buy Etch Bath and use a marker to fill it up in, if you can find it still you can thin down the etch using vinegar (too much will lower potency though). Make sure to wear protective gloves and eye protection as etch can cause horrible burns, tearing of the skin, and pretty nasty chemical scars. You used to be able to get Etch Bath from stores like michaels and Joanns and Hobby Lobby etc. but now theyre all gone, assuming from theft and liability reasons. If your looking for a better alternative they have glass etch already in a graffiti marker (mop) on amazon by searching "graffiti etch" no work, or risk in injury and work great.
