White and Gray Graniteware Colander Circa I00 Years Old

Yes still yet another colander. This one has an unusual color and texture. The base color is brown with white on top. Not sure how graniteware is made but the colors are mixed but they do not quite mix. The texture is lumpy with the white being the lumps.
Size of this colander is about 11 1/2 inches not counting the handles.
Originally I was going to post this as grey and white but I had another look at it with a magnifying glass and it is brown and white. Thought perhaps it was rust but no indeed it was brown.
It has gained an honored place among my best colanders.
