Hello Everyone, Wrong section to post this but i'll introduce myself a little in short i've been smoking pipes for 6 months i am pretty new to it but i've smoked cigars for 16 years. I recently started to smoke corn cobs after buying a dozen Briar Pipes. Last week i watched CaneRodpiper video about pipe mortar to Mod one of my cob. I mixed everything right with precision but everytime the mix is drying it all crumble back to powder is the plaster bad or something. I tried everything more water less water..... Sorry for my English im French from Canada. Thank You All
