Feature:

A Kiln that processes all stone/glass related recipes in 5s instead of 10s

Additional info:

I like what Clayworks adds but it doesn't support your blocks as of now,
I am willing to custom create all the recipes for Clayworks using KubeJS, if this isn't getting added, but it takes a lot ot time. there are a lot of recipes
It would be cool to use the Kiln instead of the Blast Furnace for some recipes aswell.
