I want to do reduction firing with alcohol drip. Does L&L provide any coating on elements to improve lifetime in such usage?
- We don't offer any coatings for elements. There is an ITC coating that some people claim to use with success. However, L&L does not recommend it because it reduces the distance between the coils which then overheats the coils and defeats any benefit you may have gained.
- The best thing to do is to completely oxidize the elements in between any reduction firing you do. Fire the kiln to cone 5 or so in a good oxidizing atmosphere. That will do the most to protect the surface the elements. Also see this link: http://www.claytimes.com/articles/improvingkiln.html
- Also - be careful of alcohol drip and any other means of producing a reduction firing in an electric kiln because of its flammability and carbon monoxide which could be generated.
