   If you after grinding anf refiring have pinholes in the glossy enamel surface, you can't conceal it. In this case, only filling the holes, refiring, grinding, refiring helps.
  
  If you accept a silk-gloss, there are some possibilities.
  
  1) Fill the holes with the according enamel-color. Make a LITTLE hill over the hole. Sieving on a VERRY THIN shift of a VERRY CLEAR flux over the whole surface. The shift should be only one enamel-powder- grain thick. Fire careful until the enamel-shift looks glossy. Now grind and polish the enamel again. Normally all holes are dissapeared.
  
  2) After grinding and polishing the surface to mat, mix a bit of the according enamel with molten wax. Depress the liquid enamel wax mix very well into the holes and make a little hill over the hole. Let cool down. Now polish the enamel surface with paper towels until the whole surface is even.
  
  3) Mix the enamel with a good, clear two-component adhesive and fill the holes in the same manner as described under 2.
  
  Let the adhesive harden. Abrade the "adhesive hills" with water and about 800-1000 fine abrasive paper. After that polish the surface as usual.

  I would like to add something. If the pores are very small and shallow, sieve on a very thin layer of very clear flux.. Fire the workpiece gently until the surface is barely smooth and shiny. After cooling, grind the excess flux carefully. Start with Carborund or diamond tools of the fineness of approximately 500-600. Grinding only until the cloisonné wires are currently to see. Then change over to finer grinding tools and continue to work as usual. But be careful. Use never flux over opaque red. The red can become black.

  I am working with copper wires. Each time I do a final firing I seem to get 1 pin hole and the enamels pull away from some of the wires. I regrind, fill and fire again and the pinhole appears somewhere else and a different spot pulls away.
  
  Does any one know why its pulling away?

  Mam to samo[blockquote]Louisa Crispin said: Pracuję z drutów miedzianych. Za każdym razem robię ostateczne wypalanie wydaje mi się dostać 1 pin otwór i emalie odciągnąć od niektórych przewodów. I przeszlifować, wypełnić i ogień ponownie i otworkowej pojawia się gdzieś indziej, a inny spot obrywa. Czy ktoś wie dlaczego jej oderwanie? [/blockquote]

   

  Mam taki sam problem.
