my experience with Etchall
Since I posted this problem with etching glass. i found out the following. No matter how clean the glass or how long it was emersed in the solution. it would not etch clear nor would it etch transparent glass effectively (blotchy). I then went and got Armour liquid brand and had no problems. It etched clear, transparent and opals in just 5 minutes. I left it in longer and didn’t change the effect of 5 minutes. In fact it echted clear a liittle to well. Have to work on that. Thanks for your post.
