Cheap as I am I prefer used dry coffee grounds, fill the void, saturate the grounds with thin CA glue and let it dry naturally. Using the accelerator will cause the CA to produce the white fuzz, which I do not want. I am trying to make this look like wood or bark inclusion. If the void is all the way through the bowl I use the blue masking tape to keep the grounds and CA glue from comming out the other side. Hope this helps. Thanks for your kind comments.
