Potters Platinum

Platinum metal may be deposited onto ceramics for decorative purposes. It is applied in a 'paint' which is then fired. This may be suitable for anodes.

Quote: 

Google for "Hanovia Bright Platinum". Englehard's 
product is used quite a bit in labs to avoid the expense and mess of 
electroplating Platinum. 2 grams of the HBP cost $15.50 at a local potters
 shop, and there is enough to do at least three or four of these anodes, 
 at about 5sqcm per anode.

Englehard's 'Hanovia' is shown here and is available on ebay from Merlin's ceramics.
