Japanese Traditional Lacquer

Japanese Lacquer is Much Much Harder Than Epoxy 

Epoxy is Mixture of In-Organic Compound

Japanese Lacquer is Mixture of Cashew Shell Sap Oil 

With 

Organic Polyester 

and 

Organic Color Dye

Japanese Lacquer is 100% Organic Compound

Therefore It is Safe for Making Food-ware

While

Epoxy Sap

is Chemical In-Organic Not Organic

Mostly From Waste

Therefore It Only Use For Floor and Furniture and Household Goods

Also Epoxy is Much Much Softer Than Japanese Lacquer

Japanese Lacquer Chemical is Really Tight Bond

I Guess It Also Had Corrode Metal Alloy

Combine with Cashew Sap and Organic High Quality Polyester

Japanese Lacquer is Hard To Find In The Market

Not For Sale

Because The Organic Polyester From Plant is Very Rare

Therefore, It Will Not Available in Market for You To Buy

Cashew Shell Sap Is Hard To Buy
Pine Sap is Easy To Find
Japanese Have Secret Tree Sap Other Than Ordinary Pine Sap Much Harder
Also Edit Version of Tree Sap Which is Organic Polymer 
It is Like Auto Paint of Toyota But Organic Instead of Chemical
Also Much Thicker Layers
Cashew Shell Oil Is The Main Key
