making hash advice

Alright so i have a half ounce of crystal
and i found this video here
http://www.youtube.com/watch?v=3qZYBw9ols8
i followed the video exactly but i noticed he made a smaller amount then what i made
and so after i was done i cut off the paper and the wrapper but it didnt hold like it did in the video is this because i didnt bake it for long enough?
i only baked it for 10
im thinking i should bake it for a good 25-30 mins
so ye lemme know what you guys think

yea just soak it in water and bake it or you can do it with your iron on low
