Question:
Hello, My wife and I are new to collecting pottery but have both grown up around antiques. We recently purchased a 5 gallon red wing union stoneware crock(handle patent date 1915). Price was $20 but is immaterial to my question because we are not selling this piece. The crock was in a local unheated flea market building and was extremely dirty. Being the type that likes to clean, I decided to buy. After a lot of scrubbing off grease with concentrated laundry detergent and using vinegar for rust stains from the handles, I found hairline cracks. They appear as two 2"x 3" oblongs on the front side at the bottom below the red wing union logo(sorry I don’t as yet have a digital camera). Also a crack goes halfway across the bottom. Strangely the crock does not leak after a week of being filled with water. This might sound odd but I really wanted to use this crock to make sauerkraut(I assume Red wing could supply a new lid if I needed one). I believe in using American antiques as much as possible and would prefer to not make this a display piece. I’m sorry to say that these days a quality American made product is usually an antique. Why Americans do not buy their own products is an issue I probably shouldn’t belabor.
Recommended repair on your FAQ’s is CA(cyanoacrylate aka super glue). Many years ago I believe sodium silicate(water glass) could be used to repair glass and pottery.
Would any of the above methods be food safe? And if I have to use this for display only is there a way to reduce the noticeability of the cracks? Thank You, I hope this question(s) was not too long. Wayne
