Susan paints the Shamrocks on by hand with glazes I created for her to use. They are fired in at 2260*F, so the Shamrocks will never fade or rub off. The tray is 15 inches in length and 7 in width and would make a great addition to your St Patrick's Day party, unless you are Irish, then you can use it all year round, (and even if you are not). The bowl is about 5 1/2 square and can be used separately from the tray. It will go in the oven and dishwasher, but it is a little too large to fit in the microwave. It is great for entertaining because it is so versatile; a chip and dip, vegetables and ranch dressing, bread and olive oil, it is a great all around serving piece.
