Glaze Recipe Test Tiles

I love the colors on these tiles and they aren't even fired yet.  

When ever I see a cone 6 glaze recipe that interests me, I pin it with intentions of one day testing it.   Months go by and the collection grows.  Finally I get around to testing and while sorting through these glaze recipes I ask myself.. How do I know if these are food safe?  This question is the main reason I'm committed to learning more about glaze chemistry.  I hope to one day be able to read a glaze recipe and based on the ingredients have a good idea if the recipe is food safe or not.   

I'm learning that glaze testing is much more than finding a pretty color and beautiful surface. Making glaze for functional ware comes with a huge responsibility.  Many things to be considered. 

I need to be sure that my pots are 100% safe for food use. I'm learning all I can about leach testing, freezing and boiling testing and dishwasher testing. 
Have a great glaze day!
