Greetings! I'm about to start a personal project—a coffee table—and I'm eager for your input. I plan to craft ceramic legs supporting a glass top, potentially raising concerns about weight. What do you recommend: making the legs hollow so a metal rod can be inserted post-firing for added strength, or is a solid design preferable? The legs should be around 14" in height and approximately 3-6" in diameter. Thanks for your insights!
