I ran across some of my college notes a few days ago and found this recipe for an Iron Oxide Wash:
1 teaspoon Iron Oxide
1 teaspoon Rutile (I've been mispronouncing this. It's pronounced roo-teel)
1 teaspoon Nepheline Syenite
2 pints water
*for black add 1 teaspoon cobalt carbonate
Is this for high fire reduction or would it work for mid range in an electric kiln?
ReplyDeleteI've seen this recipe used in both high fire reduction and mid fire oxidation. However, a good rule of thumb is to always test fire stains and glazes before using them on a piece that you have invested a substantial amount of time in. Raw materials may vary slightly from different distributors.
ReplyDeleteHi,
ReplyDeleteWill it make any difference if you put clear/transparent glaze over it?
I made a wash with just water and applied on bisque piece. I dipped the whole piece in clear and fired it to cone 6. To my disappointment the iron oxide just disappeared after firing...so I was wondering was it because of clear glaze on top or something wrong with the application...I will added NS to it and then try again..
I am guessing that the iron oxide mixed with the clear glaze. You may try using the iron oxide before the bisque firing and then use the clear glaze for the final firing. Also, you are probably already aware but it's always best to try new glazing techniques on test pieces before using them on prized pieces. Thanks for your questions. It's always great to hear from others. Let me know how your future firings go.
