A few quick questions for the glaze experts out there. Background: I'm very excited to be creating my first base glazes - a simple cone 6 clear for a white (talc free) clay body. I also have a dark red clay body with obviously a high iron content. And then after that I will be going for a cream color glaze and then a temmoku. I have no real interest at the moment in bright glossy colors. I have 2 different options for silica - sand (white) and flint (270M) - Which is the best starting point or should I just get some of both? I want to give myself the most possibilities for testing and using in secondary glaze recipes. For the base white recipe I want to use it calls for Tin Oxide Tin Oxide vs Zircopax - Tin Oxide is REALLY expensive and I am reading a lot that Zircopax although it can be substituted at around 2:1 for Tin Oxide, it tends to kill the colors that oxides produce a bit. Not too big a problem for me I wouldn't think at the moment and none of the Temmoku I want to test calls for it. Does Zircopax work in a wide range of recipes and does it have any caveats to watch out for? Thanks much! Very excited to get going and will post results as I go.
Guest posted a topic in Ceramic Events of InterestKilns: Why and How Sharon Art Center Campus of New Hampshire Institute of Art Professor John Baymore This one day seminar-type workshop will provide participants with a fundamental understanding of ceramic kilns and firing operations that they can bring back to their own studio operations. The presented material will cover underlying concepts that drive kiln function and operation, and how that information relates to designing, constructing, and firing them. This module will also assist participants in evaluating commercial units for potential purchase. Presentations will touch on gas, wood, and electric fired kilns, giving a diverse audience some practical tools. Useful handouts and a copy of one kiln plan will be provided to all participants.
