on. a hunt for terracotta glaze

hi, i am in a deep need of advice on glazes for terracotta. I love working with it and the only struggle for me now is to find the perfect matte & clear transparent satiny/glossy glazes for it. I use 2 types of clay - one of them fires to 1220 and I cannot seem to find anything that would not darken the clay so much.

I am open to mix it myself if you know a good reliable recipe since I mix all my glazes or buy manufactured one and not worry about

Any suggestion would be vvvvv appreciated

Cheers! <33
