Hello all, I am concerned about alternating firings of low/mid temperature non food safe glazes (with toxic materials) and high fire food safe glazings: I have just read (maybe it was obvious but I was not aware of it) that the toxic material can stay in the kiln bricks and be transfered to food safe glazes in posterior firings. Luckily I have not fired anything yet after these low glaze firings but I am quite concerned, what is your experience in this? Thank you so much for your inputs, Mireia

Hi Roberta, I believe the thicker the better yes, probably I am using too little glaze, maybe combined with the fact that I did not use cones so I can not confirm temperature it gives me an idea of both the problems Thanks!

Thank you Bill, I was not aware that the soak at the end would rise the cones (I'm quite new to this), so thank you. I was firing at cone 6 so I should still be in the 6 to 10 range like Mayco recommends. I will fire with cones next time to make sure the kiln reaches the correct temperature thanks! I was getting so frustrated because everyone says the glazes are so easy to use and provide consistent results :S best regards from Spain

Hi Chilly, thank you for your help, I did not use cones, I will next time to ensure they are not underfired. thank you

Good morning all, I am having consistent issues with Mayco SW colours; I love them but I can't seem to fire them right. I have been using them on white stoneware (firing temp 1240ºC-1300ºC). I have applied one, two and three coats for testing and fired up to 1250 slowly and with a 30 min period at the end. I have an electric Kiln (rohde ecotop) that seems to work just perfectly. I know I am doing somthing wrong but can't guess what; all my test tiles and pieces turn brown, I am not able to make the colours pop The colors on the tiles are stoned denim and lavender, and the castle is tyger's eye If anyone has any advice it would be very much appreciated, I am totally lost! thank ou all for your time,
