I decided to make a series of 'Old Oil Cans' recently. I just finished glazing and firing them last week and pretty happy with the results. I put finishing them on hold to make more pieces for 'Articles Fine Arts Gallery' Exhibition to be held in March. I used a Cone 6 glaze called 'Floating Red' but instead of dipping the glaze, I sprayed a light coat which turned out better than expected and they look just like rusty oil cans. The finish is matt, dry and rough to touch. This glaze is usually a variegated iron red, yellow to black, semi gloss glaze. Yellow where thinner and black were thicker. I have two variations of this recipe in my book. I used the second one. As you can see from the recipe, it has few ingredients and like any other glaze, application is the key and by spraying this and perhaps a cooler top temp, I achieved a good result.
