Hi, I am a newbie to much of ceramics, and use commercial glazes to make pieces for my mosaic sculptures. Recently I was gifted a large amount of Duncan envision 06 glazes, mayco series 2000 cone 06 and Duncan gloss 06 glazes with lead in them. Naturally, the colors I need for the 2 pieces I am working on are not there and I was wondering if they can be mixed? I know Envisions can be mixed with each other but can the lead glazes be added to the lead free? Or the Mayco to the Duncan? I know I need to just experiment but having a small kiln and limited time I wondered if anyone had any advice or experience with this I would greatly appreciate it. Also...if the lead and leadfree cannot be mixed can they be layered on top of each other...if one is translucent?
Thank you anyone for the help!
