Deep etching of glass

[Vitaly Naumov]

Hello everybody!
Who knows how to make a deep etching of glass? Looking at the pictures it is done without mica, as the texture is smooth.

Vitaly I am certainly no sign expert but I do a fair amount of etched glass and this can easily be done sand carving.

Looking at the elements on either side of the T looks sand carved to me.

there is etching and there is carving and I would say deep carved as well, this is not an etched piece, and from the "look" of the t, a nice blast. the leaf color on the unpainted part of the o looks different than the unpainted gild on the back (?) is it ?
vitaly, after rereading your post, you mentioned..."smooth" texture (?). I think anything you do to glass with pressure and grit leaves a mark and
if blasted there is a texture, even mica would leave a texture...you can "clear" / soften the texture with a clearing agent such as frog juice
but it won't be "smooth"
perhaps I'm thinking of smooth as clear glass as in slumped .
let's see the front

ps
did I just realize that this isn't you doing this panel vitaly...you're just asking how it's done, is that right ?
