Kintsugi FAQ Do the different choices of lacquer make a difference in the time taken for it to dry?
Question
Do the different choices of lacquer make a difference in the time taken for it to dry? Does it take hours or days for the lacquer to set?
and
B How long does it normally take to fix one piece from start to finish?
Shinurushi (synthetic), and cashew lacquer will dry in a normal room environment and dry within a day or two. Natural lacquer needs a warm and humid environment and takes between 2-4 days to dry, sometimes longer depending on the quality of the lacquer, the temperature and humidity. Generally speaking the higher the quality of the lacquer the longer it can take to dry.
B It depends on the complexity of the break but it can take between 2 weeks to 2 months to do a repair. A very complex break can take a year or so depending on your skill level.

Traditional, lacquer based kintsugi, steps 1, 2, and 3, fitting a piece back together
This video shows the first 3 steps to put a piece back together. I am using a rice based paste and not flour as I usually do. I also bind the piece at the top and bottom to get as good compression as possible.
Steps 1, 2, 3, refer to this page https://www.kintugi.com/?page_id=80

Kintsugi FAQ Is this a hopeless project? How to clean old material, shelf life of lacquer.
A few years back I was working on a project and became discouraged when I mis-mixed a batch of lacquer, flour and water with disastrous results. I was attempting to fill in joints after cementing the parts and the mixture was spread all over the bottom and the sides.
I have a couple of questions:
a) is this hopeless and should I start over?
b) If still viable what is the best way to clean?
c) I seem to remember you saying that lacquer has a limited shelf life. Is the material I have had since 2016 still viable for anything or do I need to replenish?
A, No, it isn’t hopeless, it will just take time to clean up. Starting over would mean scraping off the mugiurushi which never works well.
B. Hardwood charcoal that has had the tip soaked in water will usually take most materials off of a ceramic surface with some consideration given to the firing temperature of the body. The higher the firing temperature the more likelihood of success, the lower fired bodies tend to be softer than the charcoal. Store bought briquettes won’t work.
C. The shelf life of lacquer is usually about 12 months, I have only gotten 16 months at the longest. There are enzymes in the lacquer that die and render it useless.
