Fused Gecko Pattern with Mica

geckomica1

Now that you have made your fused bottle glass gecko with the free pattern for October, what else can we do with him?  One thing to consider is adding mica to him for some color and sparkle!  It’s easy, grab your gecko and we’ll get started.Mica needs some ‘tooth’ or texture to the glass to really fuse well, so, our first step is to etch our gecko.  We are going to use an acid etching paste:

As predicted, after I washed off the extra mica, my copper dots didn’t stick, ah well, such is the life of a glass artist!
