I wanted to tint a bowl so I poured about 20ml of alcohol in the bowl and put 1 drop of transtint in it and mixed it up and then brushed it on the inside. First thing that happened was a big crack opened up on the endgrain. Then I noticed the tint was already on the outside of the bowl on the endgrain sides. Amazing how it traveled thru the wood so fast!! I finished the outside surfaces and let it dry for about 30 min and the crack went back together. Maybe next time I should mix the transtint in a separate container. I do like using the alcohol, though but I need to practice more. Any other obvious mistakes you think I should know about before trying again?
