Calling all Ceramicists: Can Anyone ID this Mystery Frit...?

This ceramic material was given to me by a fellow art teacher who did not recall its original source. Now I need your help!
I use a lot of frit in my clay and glazes. To all non-ceramic folk, a frit is a ground up glass that is used to help achieve 'melt' in a clay or glaze. When materials often need a high temperature to melt, a frit is usually added to lower the final temperature, thus making the clay mature or vitrify sooner in the kiln.
When firing a ^10 glaze to ^6, a frit can also be used to lower a glaze temperature to achieve proper melt, or so the theory goes. I haven't done this, as it can be a bit tricky, but it can be done.
But I need help. I am trying to identify this material. I have been told that it is a leadless frit, but that is about all I know. Perhaps someone who reads kanji can help translate this for me so that I can begin testing. All I know is that it is a frit of some source and I need a place to start testing it.
If any of you out there can tell me more about this product or where I can learn more about it, please drop me a line.
