Raku ?? I LOVE Raku !!! The only thing I've found so far is this link and something on Pinterest :
http://harrachglass.blogspot.com/201...-tutorial.html
you've probably already seen it.....then there was something about encasing the beads to further bring up the colors. it looks so pretty and interesting to work with that glass.....I guess (they keep telling me) practice practice practice is the thing lol......loads of patience too, I think I'll need it, there's so much to learn.
~peace & love
