I heat 500 ml at a time. 3:30 in the mcrwv, then stirr, add color, zap for 1:20, wait about 2:00 for the bubbles to settle, zap another 1:00 and ready. I do think it takes longer to prepare that the LC did, but I think it stays liquid longer. I ordered the Hand Pour Medium. The bucket says "Hand Pour Soft", but it is a medium strength plastic. I suppose they just added hardener to a soft plastic and mailed it. The cost was $40 plus shipping for 5 gallons. $25 to Hidalgo Texas.
