Celia it probably costs more for lowfire glaze ingredients but I can get a 10kg glaze bucket for £8-12 using raw materials when it is £40 and up for premixed. I think cone 10 is cheaper on ingredients but it sound strange that you can't make it for less.
Think I must have opted for a complex recipe to do my comparison exercise. Will look for another recipe and go through the exercise again!
