Custom Raku Glazes

Hi there folks,

I'm new to the group and fairly new to pottery as well - started not that
long ago and got hooked INSTANTLY.

My question is this:

I've done some raku with commercially available glazes at the studio where
I'm learning and started looking online at different colors/tones that might
be available. I found A LOT of recipes for 'mix it yourself' glazes. How
difficult is it to find the materials and make these glazes yourself?

Thanks,
Tina
