I have a large cherry burl that I am making into bowls. The wood is not spalted, but there are thousands of hairline cracks in it. Normally for cracks like this I would wick some ca into it to strengthen and fill it. In this case, there are so many I can’t ignore to potential for food contamination. While I’m intending for these bowls to be decorative, there is always the possibility someone could put salad into one. Is there a food safe alternative to ca? If not, should I mark as not food safe? Or am I just overthinking this?
