Hi, am making charcoal briquette using 3% starch as binder , 6% sodium silicate and 4% clay, I got a good briquette with no cracks, but the problem is, the ashes stuck on my charcoal briquette, and I need to shake it hard to remove ashes even I reduce clay to 1% and same problem. Anyone can advise me how to solve the ash problem
