Does the wind furniture of the Ming Dynasty contain formaldehyde,

The original solid wood does not contain formaldehyde. But the kind of artificially made solid wood board is glued together, so there will be formaldehyde released, of course, it is less than the formaldehyde of particleboard.

Yes, there is nothing that is completely excluded, otherwise the whole process will not be done, but it will be relatively small.

Formaldehyde is an indispensable main component of woodworking boards, paints and other materials, woodworking boards without formaldehyde will crack, paint will peel, so as long as your furniture uses these materials, formaldehyde must be exceeded.

Solid wood home to be painted, will also contain formaldehyde, compared with other wooden furniture, relatively less much, volatilization time is much shorter!

It is difficult to say, mainly depending on whether the wood in the steel and wood furniture is made of solid wood or multi-layer board or MDF, etc., if it is solid wood and no glue connection to achieve formaldehyde-free, on the contrary, if other multi-layer boards may contain formaldehyde.
