Thanks every one, The wet spot, The coconut oil that I added should have taken care of that , from what I have read. I like the thought that it may be a temperature problem, if the glass has a thicker bottom then the temp on the bottom would be colder, that makes sense, this was poured on its own but when they are poured huddled in a grouping would this eliminate the problem, or the other option is to pour at a slightly higher temp to begin with, so that it does not cool down to quickly. As you can see I like to ponder the solution before trying out several things, otherwise I end up with glasses all over the place with my testing, some times 20-30 of them, I have sort of learnt in the past to analyze the problem then try something close to the answer.
