After the gaps had been filled I removed any surplus enamel from areas on the silver, and also managed to remove large chunks from 3 of my nails and some skin without noticing! Not sure if I was concentrating hard or it was as it was under cold running water that I did not notice. Lastly one more firing to make the filed glass shiny once more.
The biggest lesson I learnt was to protect my fingers when cleaning up! I also think the areas of enamel to silver need to be larger to give a better effect, and perhaps better washing of the enamels would give a clearer effect.
Having a go was the best lesson.
