No I wasn't, merely suggesting a quick "option" rather than a long drawn out process running over months. Saves time and money. I was just doing what this forum is designed for..... sharing information and tips that are picked up along the way. People then can decide if it suits them or not.
Jonathan - it's a test I have seen people mention on the T-Shirtforums. Haven't done it myself as I'm upto speed on my current mug supplies on where the coating stands. From what I read it seemed to expose the weaker coatings. They had several mugs that had photos shown after the test which showed some had faded badly and others still looked good. I believe the theory was based on that a dishwasher gets to a temp below what the test is at and only stays there for a couple of minutes or less. With the test be a bit hotter and for a prolonged period in concentrated dishwasher solution then it seemed feasible to me that it provides a good benchmark.
If you remember the test from Listawood on RN and Orca then that was submerged in water with detergent of some sort for a given time. I suppose this one works a bit quicker due to the extra heat. Might not be quite as accurate due to not keeping the same temp as a dishwasher but seems a quick fix.
If I see the thread on tsf I'll post a link.
